Imminent Water Crisis In India

Imminent Water Crisis in India

Agricultural Despite the recent rapid growth in the services and industrial production, agriculture is
still an integral part of India's economy and society. Between 1947 and 1967 India underwent the
Green Revolution, which concentrated on expanding farm yields by double–cropping existing
farmland and using seeds with improved genetics.[9] The result was a huge increase in agricultural
production, making India one of the world's biggest exporters of grain. The availability of canal
water led farmers to adopt highly profitable, but extremely water intensive crops, such as sugar
cane.[10] In addition, India achieved its goal of obtaining food security. The rural economy sustains
two–thirds of India 's 1.1 billion citizens.[11] Unfortunately, this huge surge in agriculture, required
significant water resources for irrigation and accelerated the onset of present water shortages. India's
agricultural sector currently uses about 90% of total water resources.[12] Irrigated agriculture has
been fundamental to economic development, but unfortunately caused groundwater depletion. Due
to water pollution in rivers, India draws 80% of its irrigation water from groundwater.[13] As water
scarcity becomes a bigger and bigger problem, rural and farming areas will most likely be hit the
hardest. Thus far, food security has been one of the highest priorities for politicians, and the

North American Migratory Bird Species
North American migratory bird species that forage on air–borne insects, known as aerial
insectivores are experiencing widespread regional declines in population, but the cause remains
poorly understood (Paquette et al., 2014). Climate change as well pesticides which both cause
changes in the abundance of insect prey can be a possible cause (). Agricultural and farming
intensification in addition to other land use developments on the birds over–wintering habitat may
also be a contributing factor to aerial insectivore decline (Fraser et al., 2012). For example,), have
shown that numerous environmental pressures have rapidly decreased the population of many insect
species. This has led to a steep decline in aerial foraging bird populations. ... Show more content on

To begin with, in order to understand mechanisms that influence avian population changes
biologists often seek to explore similar characteristics such as biological and ecological similarities
that occur across entire 'guilds'. A guild in this sense, is a grouping of species sharing a common
life–history or an ecological trait such as a shared niche. There are numerous guilds that could be
classified according to factors such as comparable habitat and food varieties, reproduction and
clutch size, as well as migration and nesting strategies used by the species in question. The guild of
'aerial insectivores'– consist of birds that feed exclusively on flying insects. These insects include
flies, mayflies, moths, butterflies, grasshoppers, crickets, beetles and other insects Aerial
insectivores in other words, are classified as a dietary guild because of their similarities in allocating
food resources. The guild of aerial insectivores consist of flycatchers, nighthawks, martins, swifts,
swallows, and whip–poor–wills As this research essay is constrained in its nature it is thus
impractical to spotlight the entire guild of aerial insectivores. In this research essay rather, I will be
focusing on one particular species of aerial insectivore: Chrodeiles minor, otherwise known as
common nighthawk, a species that consists of nine subspecies that inhabit Canada (as well as the
United Sates) during the breeding season from May to

In an arid land, there is less precipitation than the potential evaporation which is not the case in
humid regions. 2. What is meant by an impermeable surface and how does such a surface influence
the results of rainfall in a desert? An impermeable surface cannot be penetrated by any element.
Such a surface will not allow rain to percolate into the desert soil leaving no plants with root
systems able to survive unless specifically adapted to the climate. 3. What is a basin of interior
drainage? The land is uplifted crust blocks that form parallel ranges but surface water doesn't run to
the ocean. Instead, it evaporates over time leaving a salt flat. 4. What is the difference between an
ephemeral stream and an exotic stream in a desert? An ephemeral stream is a stream that only exists
during rainfall. Exotic streams come from an origin outside of the desert. 5. Although there is very
little rainfall in deserts, running water is still the most important process of erosion and deposition in
arid environments. Describe and explain at least two special conditions in deserts that tend to
increase the likelihood of fluvial erosion whenever it does rain. Any rainfall increases fluvial
erosion. When rain does fall, this creates ephemeral streams causing water erosion due to fast forces
of water. Flash floods are possible as well creating even more erosion. 6.

How Annual Planetary Albedo Is Affected By The Forcing...
In this section, we will look at how each factor was affected by the forcing boundary conditions set
in the six experiments we ran. The results section will be organized in sections by factor.
Annual Planetary Albedo
First we will address results about how annual planetary albedo was affected by altering the forcings
in the simulations. Overall, when comparing Control Experiment (Modern Specified SST) to
Primary Experiment 3 (Ice Age 21kya run), we observed a relatively higher planetary albedo during
the Last Glacial Maximum, with an average of 2.37% increase. In areas with known ice sheets, such
as the Laurentide Ice Sheet over the upper section of North America or the Scandinavian Ice Sheet
over Northern Europe, there was a much more drastic change in albedo. In these regions, the albedo
was significantly higher during the LGM, up to 27% higher in certain areas. Albedo was also higher
south of the equator in the oceans surrounding the Antarctic. Some parts of the earth had a near–
neutral change in planetary albedo, mostly in low latitude areas like the tropics. This can be seen in
Figure 1. When put side by side, Figure 1 shows little resemblance to Figure 2, the map comparing
annual planetary albedo of Primary Experiment 1 and the Control Experiment. This comparison
shows little to no consistent change in albedo between the two eras, with a planetary average change
of 0.02%. There are clusters of regions with a very high increase in albedo between the modern

Volcanism of Long Valley, California: The Bishop Tuff Eruption
The west coast of North America has been tectonically and volcanically active for billions of years.
The Sierra Nevada Mountains in eastern California were born of volcanoes, and magma has been
erupting in the Long Valley to the east of the mountains for over three million years (Bailey, et. al.,
1989). However, the climactic eruption of the region occurred relatively recently in the region's
geologic history. About 760,000 years ago, a huge explosion of magma warped the Eastern Sierra
into the landscape that exists today. The eruption depleted a massive magma chamber below the
earth's surface so that the ceiling of the chamber imploded, forming what is now known as ... Show

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in
the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then
silica–rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years
ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they
were erupted from the mantle, while the slightly younger domes and flows were from a deep–crustal
source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass
Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al.,
1989).
This chamber gave birth to the cataclysmic eruption of 760,000 years ago, and is connected to the
magma which erupted from the chain of rhyolite domes that stretch up to the northwest. Eruptions
crept sequentially along this line, beginning with the Bishop Tuff eruption and most recently
displaying activity in the middle of Mono Lake at the island Negit. This most recent volcanism of
the Inyo–Mono crater eruptions occurred as late as 1850 A.D (Bailey, et. al., 1989).
The cataclysmic eruption which caused the collapse of the caldera and the deposition of the Bishop
Tuff was an explosive, fast event. It ejected coarsely porphyritic biotite rhyolitic ash and viscous
lava with an approximate silica content of 76 percent. The total ejecta came to about 600

Global Warming Has Left Upon Our Natural Environment
Introduction
With July 2013 recorded as one of the worst snowfalls in the history of Australia winters, well
concerned fears are fulminating regarding the future of the ski industry, namely the ski resorts that
reside in the Snowy Mountain region including Thredbo, Perisher, Charlotte's Pass and the Selwyn
Snowfields, and several major Victorian ski resorts including Mt Buller, Mt Hotham and Falls
Creek. The Alps are the only region on the Australian mainland in which deep snow falls naturally,
however, with the ongoing impact that global warming has left upon our natural environment, it
feels ominously close that the premonition of a snow–deprived winter may be as soon as 2050.
More erratic looking winters have confirmed the beliefs of many that the ski industry may not be
viable beyond the mid–century mark, given that the ski industry's economic viability is highly
sensitive and contingent on the number of days with good snow cover that are received each year.
According to a government commissioned report, the ski industries initial fears are well–founded
with ski seasons to be predicted to be 10 weeks shorter, and the snow depth considerably declined.
While some may reflect upon the 2013 winter and overlook the enormity of the issue, scientists
predict that the impact of global warming means the long–term outlook for the ski–industry is bleak,
and not positive. Not only does a lack of snowfall presents environmental consequences, but also
poses a series of consequences

The Melting Of An Ice Age
An Ice Age is a period of geologic time in which the Earth's climate sees a dramatic drop in
temperatures. This basically means that it is a lot cooler than it was in different parts of earth's
geologic history. As a matter of fact, earth is believed to be in the middle of a glaciation period
currently because of our polar ice sheets. As we know it today there were about six ice ages that
have occurred throughout the history of the earth. Glaciation periods have helped shape the earth as
we know it today and has helped humanity progress down its evolutionary track. Though it is agreed
upon that several ice ages have occurred during earth history, the cause of these cycles is still a
mystery waiting to be solved. The Huronian Glaciation or "Snowball Earth" is believed to be the
oldest ice age in earth's history. Roughly 2.4 to 2.1 billion years ago. During this particular ice age,
ice cover the earth from pole to pole, the entire planet was frozen, nothing could survive. Our next
two ice ages were during the Cryogenian Period, which is nicknamed the "Deep Freeze" because
this was the deepest cold the earth has ever experienced. The Sturtian Glaciation 750–700 million
years ago, and the Varanger/Marinoan Glaciation which occurred 660 to 635 million years ago.
There is a possibly that the earth was a snowball at these glaciation periods but proof has not been
provided yet. The Andean–Saharan ice age during the end of the Ordovician period and beginning
of the Silurian period

Rapid Climate Change Events During The Period Between 10ka...
The last glacial period has encountered numerous large–magnitude, rapid climate change events;
characterising the period between 10ka and 50ka (Steig, 1999). During this period was the Last
Glacial Maximum (LGM), which occurred approximately 21ka, a glacial period defined by changes
in greenhouse gases, sea level and ice sheets (Otto–Bliesner et al., 2006). In comparison the mid–
Holocene occurred approximately 6000 years ago, during the current interglacial. The Holocene
period is regarded as relatively muted in terms of 'signals' of climate change, with changes primarily
associated with changes in seasonal solar radiance (Otto–Bliesner et al., 2006; Steig, 1999).
Models have been constructed in order to replicate the past climates, with specific reference to 'The
Community Climate System Model: Version 3' (CCSM3), aimed to define continental scale
dynamics, variability and climate change (Collins et al., 2006). With the use of models the
environmental variation between the LGM and mid–Holocene periods can be construed. Roche et al
(2007) refers to the LGM as the classic benchmark for models, enhanced by the use of proxy data
associated with ocean surfaces, vegetation, oceanic–circulation and atmospheric conditions.
Clark et al (2009) presented the extent of the LGM, with growth of ice–sheets to their maximum
extent occurring between 33ka and 26.5ka; primarily in response to climate forcing from decreases
in northern summer insolation, tropical Pacific sea surface

Causes Of The Neolithic Revolution
Initiation of the Neolithic Revolution
When considering the most plausible theory for the catalyst that began the Neolithic Revolution,
one must look directly at the changing climate of the region. Approximately 18,000 BC, the earth
was experiencing a climactic transition, brought about by the end of the Last Glacial Maximum.
During this transition the earth began to experience warming temperatures, which dramatically
changed the landscape, and the very existence of the hunter–gatherer populations. The oscillating
temperatures that occurred during the next few thousand years help guide the trajectory of
development in agriculture and human societies.
While considering the weather, Barry Cunliffe, author of Europe Between the Oceans states, "By
about 12,000 BC dense forest covered much of the western part of the hilly flanks region, giving
way, around its borders, to more open areas where extensive stands of wild wheats and ryes could
flourish" (91). This period of warmer weather is referred to as the Holocene. The thawing ice sheets
also caused water to rise, and subsequently change not only the structure of the land, but the plant
life as well. As the hunter–gatherers adjusted to these changes in their environment, another
climactic event ensued called the Younger Dryas. The Younger Dryas was a dramatic, and brief
return to the cooler, dryer climate experienced as the Last Glacial Maximum was ending. The
general thinking is that this phenomenon occurred due to very cold

Why Did The Diprotodon Become Extinct
Introduction
Megafauna simply means "big animals" and is a term mostly used to describe a particular group of
large land animals which evolved millions of years after the dinosaurs became extinct. These
animals generally have a body mass which is greater than 40 kilograms.
Diptrotodon
The Diprotodon was the largest and the best known of the megafauna.
The Diprotodon co–existed with humans for thousands of years before becoming extinct some
25,000 years ago. It was also the last megafauna to become extinct.
They were widely spread throughout Australia, including the Darling Downs in Queensland,
Wellington Caves in New South Wales. Naracoorte Caves in South Australia and Bacchus Marsh in
Victoria, just to name a few.

Appearance
The Procoptodon was a huge kangaroo which grew up to 2 metres in height and weighed up to 200
kilograms.
The Procoptodon had a short, flat face and forward facing eyes and an upright posture.
The lower jaw was big and a chin was developed. It had small incisors on the upper and lower jaws
for nipping the vegetation.
It had long and mobile forelimbs with the two middle fingers having long, recurved claws enabling
them to be used like a hook to grasp leafy branches.
It had a single toe on its feet which had a hoof–like claw on the end of it. This may have helped give
the Procoptodon a greater measure of speed. It is believed that the number 2, 3 and 5 toe bones were
so reduced that they were lost and the well developed number 4 toe formed into a single toe.
Habitat
Procoptodon were mainly in arid or semi–arid regions on New South Wales and South Australia.
Many areas were harsh environments being treeless, wind–blown sand dunes. Having been found in
The Lake Menindee area in western New South Wales, it was a somewhat cooler and wetter climate
than what it is today. The surrounding areas had forests, woodland, savannah and plains with
windblown sand dunes on the edges of the lake. Procoptodon have been found in caves in the
Nullarbor Plain in a dry open environment with hard leaved

Iodp Site 913 Glaciations
The Onset of the Northern Hemisphere Glaciation

Student at Stockholm University

Introduction
The Northern Hemisphere Glaciation (NHG) is believed to have initiated into large scale, permanent
ice sheets ~2.5 Ma, which is almost 31.5 Ma after the initiation of the Antarctica ice sheets. There
are many possible causes for the onset of this climate event, some of which we will be reviewing in
this essay. In this essay we will look at the cores from IODP and ODP sites 302, Arctic Ocean; 913,
Greenland basin; and 907, north of Iceland, in order to identify the characteristics and possible
causes of the northern hemisphere glaciations. First we will look at the evidence for the onset of this
event and the proxies ... Show more content on Helpwriting.net ...
However, proxies show that the initiation of IRD ~46.25 Ma at site 306, correspond to a >1000 ppm
decrease in CO2 gases in the atmosphere (See Figure 5. Note. From 'Cenozoic ice–rafting history of
the central Arctic Ocean: Terrigenous sands on the Lomonosov Ridge' (St. John 2007)). This
correlation between IRD and pCO2 is critical since it leads us to the hypothesis that a decline of
pCO2 could have driven the climate in the polar regions over a temperature threshold, which
enabled the onset of continental glaciers and ice sheets on the surface of the Arctic Sea (St. John
2008). This is only one of many possible reasons of the NHG onset, where other potential causes
suggested for the initiation of the NHG are: events of mountain building; plateau uplift in southern
Asia and the American West; Volcanic triggering, resulting in aerosols in the atmosphere; and the
closure of Panama Seaway, which would have changed the whole ocean circulation and distribution
of cold vs. warm ocean water (St. John et al.

The Sunderbans, located in West Bengal, have been particularly susceptible to typhoons arising
from the Bay of Bengal. Farmers have relied on embankments to segregate saline sea water from
engulfing their soil but the devastation caused by Typhoon Aila in 2009 destroyed approximately
900 kms of embankment thus salinating many miles of agricultural land. This prompted Kolkata
NGO, Society for Environment and Development (ENDEV) to look into introducing strains of
paddy rice which were resistant to saline water and soil thus providing farmers a lifeline to their
crop yield.
ENDEV activists took a year to identify five indigenous salt resistant seeds :
Hamilton

The NGO then collaborated with five other organisations in the Sunderbans to propagate the new

Commentary On Housekeeping By Marilynne Robinson
Commentary on Housekeeping by Marilynne Robinson Housekeeping by Marilynne Robinson is a
coming of age novel recounted in the first person by one of two sisters as they grow up in a small
town near a glacial lake in Fingerbone, Idaho. The novel is full of polished lyrical prose and

importance of family, abandonment, and the impermanence of things. Early in their lives, two young
sisters, Ruth and Lucille, experience loss and abandonment from the men in the family. Their
grandfather had died in a train derailment into Lake Fingerbone before they were born, and their
father leaves them while they are very young. Then their mother commits suicide, but not before

feelings of invisibility. "I often seemed invisible... made no impact on the world... was privileged to
watch it unawares" (106), Or how some people live their lives, not by the clock, the sun, or the

Glaciers-The Identity Of A Glaicer
The Identity of a Glaicer Glaciers have helped define the topography of earth for many years. A
glacier is a large mass of ice that has been compacted of snow and ice for a long period of time. The
ice age we will be focusing on is the Pleistocene era, which was "a period that began about 2.5
million years ago and ended about 10,000 years ago" (513). This was the most recent ice age where
it helped formed our present–day lands. During this time, ice covered about 19 million square miles
which was about 1/3 of earth's land surface (515). Many parts of all the continents were covered
with ice and that had a great effect on our topography due to the glaciers it created. The two primary
types of glaciers are continental ice sheets and mountain ... Show more content on Helpwriting.net

The moraines is a "general term for glacier–deposited landforms composed of till" (526). The
features usually are irregular and is normally longer than wider. The three types of moraines in
glacial deposition of ice sheets are terminal, recessional and ground. Terminal moraine is the front
part of a glacier where all the power is. Although glaciers may appear to stop moving forward, the
internal part of the glacier continues to give strength to its movement. Recessional moraine is right
behind the terminal moraine where the ice would spread out putting pressure out to the edges in
bulges. The last type is called ground moraine and that is when "large quantities of till are laid down
from underneath the glacier rather than from its edge" (527). A feature we see from the glaciers
deposition is an "elongated hill" (527) called a drumlin. These long, small hills that are usually in
groups, are much smaller than moraines but still made predominantly of

The first monument consisted of a circular bank and ditch enclosure made of Late
Cretaceous Seaford Chalk, measuring about in diameter, with a large entrance to the north east and a
smaller one to the south. It stood in open grassland on a slightly sloping spot. If this were the case, it
would advance the earliest known stone structure at the monument by some
500 years. A small outer bank beyond the ditch could also date to this period.These remains had
originally been buried individually in the Aubrey holes, exhumed during a previous excavation
conducted by William Hawley in 1920, been considered unimportant by him, and subsequently
reinterred together in one hole, Aubrey Hole 7, in 1935. Physical and chemical analysis of the

Also, by clearing forests to support agriculture, we are transferring carbon from living biomass into
the atmosphere (dry wood is about 50 percent carbon).
The result is that humans are adding ever–increasing amounts of extra carbon dioxide into the
atmosphere. Because of this, atmospheric carbon dioxide concentrations are higher today than they
have been over the last half–million years or longer.
– The Carbon Cycle; The Human Role, Earth Observatory, NASA
Another way of looking at this is with a simple analogy: consider salt and human health:
A small amount of salt is essential for human life; Slightly more salt in our diet often makes food
tastier; Too much salt can be harmful to our health.
In a similar way, greenhouse gases are essential for our planet; the planet may be able to deal with
slightly increased levels of such gases, but too much will affect the health of the whole planet.

the latter is rapid. This means that ecosystems have less chance of adapting to the changes that will

Global Warming And Its Effects
Global warming is a subject that elicits different opinions, even in the political sphere. During the
2016 presidential campaign, the Democratic candidates all declare that global warming is a national
crisis and that some policies need to be implemented. On the other hand, the majority of the
Republican candidates claims that global warming is all a hoax and that designing policies to
combat global warming are a waste of money and energy. The different stances happening in the
political sphere are also happening outside of the political sphere. Everyone in the world has
different views on global warming, but very few of us did anything to lessen the impact of global
warming in that the majority of us each drive our own fossil fuel–using vehicles instead of using
public transportation, and the majority of us rarely reuses and recycle. Global warming occurs when
carbon dioxide and other greenhouse gases trap heat in Earth 's atmosphere because some of the sun
's rays cannot escape. It is a worldwide phenomenon that impacts each and every one of us because
it cause irregular climate patterns, increases the sea levels, and decreases human living standards.
We can usually anticipate what the temperature will be the next couple days because there is a
normal pattern to it, the temperature will be stable throughout the months until the season changes
which will cause an increase or decrease temperature depending on which season is next. But
recently we have not been able to

Ohio's Ice Age
Although difficult to imagine, Ohio has at vari– ous times in the recent geologic past (within the last
1.6 million years) had three–quarters of its surface covered by vast sheets of ice perhaps as much as
1 mile thick. This period of geologic history is referred to as the Pleistocene Epoch or, more
commonly, the Ice Age, although there is abundant evidence that Earth has experienced numerous
other "ice ages" throughout its 4.6 billion years of existence.
Ice Age glaciers invading Ohio formed in cen– tral Canada in response to climatic conditions that
allowed massive buildups of ice. Because of their great thickness, these ice masses flowed under
their own weight and ultimately moved south as far as northern Kentucky. Oxygen–isotope analysis

Lake deposits are primarily fine–grained clay– and silt–size sediments. The most extensive area of
lake deposits is in north– ern Ohio bordering Lake Erie. These deposits, and adjacent areas of wave–
planed ground moraine, are the result of sedimentation and erosion by large lakes that occupied the
Erie basin as Wisconsinan–age ice retreated into Canada. Other lake deposits accumulated in stream
valleys whose outlets were temporarily dammed by ice or outwash. Many outwash–dammed lake
deposits are present in southeastern Ohio far beyond the glacial boundary. Peat deposits are
associated with many lake deposits and formed through the accu– mulation of partially decayed
aquatic vegetation in oxygen–depleted, stagnant water.
The term glacial drift commonly is used to re– fer to any material deposited directly (e.g., ground
moraine) or indirectly (e.g., outwash) by a glacier. Because the ice that invaded Ohio came from
Canada, it carried in many rock types not found in Ohio. Pebbles, cobbles, and boulders of these
foreign rock types are called erratics. Rock collect– ing in areas of glacial drift may yield granite,
gneiss, trace quantities of gold, and very rarely, diamonds. Most rocks found in glacial deposits,
however, are types native to

Minnesota's Glaciers
The Wisconsin Glaciation of Minnesota
A glacier is a large body of ice that moves slowly across land and are formed by there being a higher
snow gain rather than a snow melt. Glaciers move by a small amount of ice melting and the glacier
sliding. Glaciers can help and destroy the landscape in front of them but they can also shape the land
into something amazing. Glaciers were once present in Minnesota thousands of years ago and
played a massive role on the landscape we live on today, and as they melted they left behind large
amounts of water and formations. The glaciation is very confusing to those who don't know about
glaciers so here is some background information. The last glacial advance started about 75,000
years ago and the last ... Show more content on Helpwriting.net ...
Outwash and till are similar but different at the same time and this is why they are both deposited by
glaciers, but the way they are deposited is what makes them different. Till is simply the sediment
left by the ice, outwash is deposited by the running water coming off of the melting glacier. Because
water can sort sediment, and ice cannot, that is why the till is unsorted. Sorting just means when the
rocks are sorted by size, bigger pieces together on the bottom, smaller pieces together on top.
Glaciers are constructive and deconstructive they are deconstructive because they tear up land and
the glacier does not stop for anything but it is easy to avoid. Glaciers erode the land and create
landforms such as kames, eskers, and drumlins those terms will be explained a little bit later.
Glaciers create valleys by shearing away the mountainside and moving it away. Some of the
landforms that glaciers produce are drumlins, terminal moraine, outwash plain, and an erratic.
Drumlins are elongated, teardrop–shaped hills of rock, sand, and gravel that formed under moving
glacier ice. A terminal moraine is where the glacier reaches its max and starts receding making a
deposit of till. An outwash plain is a flat area made by meltwater carrying outwash from the leading
edge of the glacier. An erratic is a rock or boulder carried from a place where the Rock is common
to an area where the rock is not

Case Study: Don Valley Brickyard
Sarah Hall, 1000680872 September 23, 2014
Lab 1: Don Valley Brickyard Short Pre–Lab Report
1. The geology of Ontario is divided into three layers of rock. The first layer, Precambrian Canadian
Shield rocks, is composed of mainly igneous and metamorphic rocks from the Precambrian Eon.
This layer is the eldest at approximately 3–0.8x109 years old and is therefore the bottom–most layer
(L). Although this layer is largely found in the Canadian Shield region of Ontario, glacial erratics
from the Precambrian layer can be found at the Don Valley Brickyard (L). In the GTA, younger
sediments and rocks cover the Precambrian rock layer (L). The second layer is Paleozoic rock,
composed of sedimentary rocks . It was deposited 600–400 million years ... Show more content on

The 440 million year old Georgian Bay Formation is largely composed of fossiliferous grey–black
shale (L1R). It also consists grey fine–grained limestone, sandstone and green/grey siltstone
interbedded with green/grey and blue/grey shales (Bond et. al. 1976). The frequency of hard rock
units increases toward the top of the formation. Recurrent tropical storms across the Ordovician seas
caused the formation of shady, thin limestone with wave ripples on top. Numerous fossils can be
found in the siltstones and limestone including molluscs, crinoids and gastropods

Strange Cave Research Paper
Mountains is Bear's cave named for the cave bear fossils discovered in the cave. Ciur–Izbuc Cave
known as the cave of bones houses the oldest foot prints known to be found at 36,500 years old,
evidence shows that seven individuals entered the cave including a child, after a flood. Focul Viu
Glacier is the third largest underground glacier in Romania, and Bortig Pit Cave contains the second
largest glacier in Romania. Another interesting underground feature is the Movile cave located near
the Black sea and Bulgarian border in the southeast. Sealed off from most of the outside world this
poisonous cave is home to many strange creatures, scorpions, spiders, snails, shrimp, and more, all
living in darkness and low levels of oxygen. The Movile cave was discovered by a group
researching the land for a power plant and has had less than one hundred humans in contact with it.

The sphinx resembles the Great Egyptian Sphinx. The Babele are mushroom shaped rock
formations. Both of these are the result of wind and rain erosion, and are now tourist attractions in
Romania. Another area of interest is the Red Ravine located on the Secaselor Plateau near the city of
Sebes. The mountain side has a distinctive sharp pointed appearance to the rocks caused by runoff
erosion. The red color comes from the sandstones, quartz sand, and gravel and the vertical wall
reaches heights of fifty to one hundred twenty five meters and forms deep ravines during the rainy
season. Bigar Cascade falls in Caras–Severin part of historical Banat region, are a unique falls

Elora Gorge Research Paper
This photograph was taken on a field trip to Elora Gorge. Elora Gorge is an important landscape in
Ontario and is also a prime example of significant change to a landscape by physical processes.
Largely, it is the result of erosion by water at the end of the last glacial period. The most recent
glacier over North America, the Laurentide Ice Sheet, resided almost all over Canada. Eventually,
the sheet melted, allowing water possessing a strong stream discharge to be released in numerous
directions. One of these melt–out pathways formed the Elora Gorge. Similar to how other gorges are
created, it was the energy of the river water rushing from the melting glacier that was able to cut
into the surface of the bedrock. Streams carved through

Art Analysis: The Ice Age
Introduction
"The Ice Age". Hearing these three words, you might think about the delightful animated kids
movies that our modern culture has come to love. You might think about how old the ice cubes are
that you put in your freezer a while ago. But by the end of this section, in which you will learn about
glacial forces, your appreciation for "The Ice Age" will surpass boundaries that you never dreamt
were possible. While the average human being's understanding of the ice age may remain limited,
you may find yourself becoming what some may call "an expert" on how glacial forces shaped the
Howe Sound – Whistler region.
As the glaciers (about 2 km thick) travelled from north to south, it created many geological features
such as fjords, hanging ... Show more content on Helpwriting.net ...
Ice came out of the hanging valley and into Howe Sound. We can tell this because the granite has
striations. Glacial striations are scratches or gouges cut into bedrock by glacial abrasion. These
scratches and gouges are a result of a moving glacier. The glacial polish is a characteristic of the
rock surfaces after the glacier has passed over the bedrock. Shannon Falls is a Bridal Veil Falls,
formed by the steep drop from the hanging valley to the main valley floor usually creating cascading
waterfalls.
Erratic rock at Shannon Falls 6
In this photo, you can see some erratic rock on the way up Shannon Falls. The scale is shown by the
inclusion of a tasty Fibre 1 bar, now with only 130 calories. The erratic rock differs from the
surrounding rock, as it was brought from a distance by glacial action.
Erratic Rock at the Chief 7
This photo is of some erratic rock found in the forest along the hike up the chief. When the massive
glacier moved through Howe Sound, it brought with it this erratic rock from a long distance away.
This is why this rock appears different than the other surrounding rock. The rock was brought here
through a process known as 'plucking', which is defined as the erosion and transport of large chunks
of rocks. As a glacier moves over the landscape, water melts below the glacier and seeps into cracks
within the underlying

Ice Ages: An Alien Idea
Ice Ages: An Alien Idea
In 1827 Louis Agassiz was the first to scientifically propose that the Earth had experienced a past
ice age, which he said could explain previous observations that erratic blocks of alpine rocks
scattered over the slopes and summits of the Alps, had been moved there by glaciers. He presented
the theory that ancient glaciers had traveled throughout the entire northern hemisphere and
deposited these rock formations along the way. Though many before him had theorized moving
glaciers, he was the first to label this period of time as the Ice Age.
Consequently, he knew that he would need to defend his ice age theory, so he established a glacier
observatory where people could visit and experience firsthand the effects that

Run In The Light Analysis
In today's society, we feel as though trivial hardships seem like enormous obstacles that prevent us
from prevailing in life. Humans in the twenty–first century believe as though the hindrances we
encounter are far worse than those of our ancestors. In this sense, we become a tad oblivious to our
own history. We have become so accustomed to resources being readily available for us that we
never question how the first Americans, who did not have the kinds of resources we have today,
created a proficient civilization. The Paleoindians, also referred to as the Clovis People were one of
the first inhabitants of the American continents. This historic migration occurred towards the end of
the last Ice Age between 10,000–40,000 years ago. The Paleolithic ... Show more content on

The way Mr. Ware describes his emotions towards the characters, in the beginning, was exactly how
I felt. Runs In the Light is an underestimated individual who we want to see succeed right from the
beginning of this novel. Raven Hunter isn't necessarily evil but as Ware has said he was selfish
compared to his brother. Many of the questions in this review were similar to ones I had while
reading. I agree that this novel has a more modern tone to it as the novel could have incorporated the
time period more. However, I disagree with how Ware said that the pacing of this novel was
excellent. As I read the book, I felt as though the middle portion dragged on and the details could
have been written in a more intriguing manner. This novel had a potential to be really interesting but
in the middle, it dies down losing the reader's attention and focus. Nevertheless, I do agree with
Ware's statement on the characters' names. While I do understand that the authors chose such names
to incorporate a pre–historic impression, the names made the novel incredibly difficult to follow. I
repeatedly got a couple of the supporting character confused. In addition, I agree with Christopher
Ware upon the fact of becoming attached to the characters. Throughout the novel, I was always
rooting for the antagonist and hoping to see a certain group succeed and sympathized with others.

Glacier Ice Research Paper
Glaciers and Desserts Exercise
The difference between an ice sheet and a glacier; an ice sheet or continental glaciers is a chunk of
glacier ice that is the largest and the thickest type of glacier that can be almost unbelievable. They
are massive and can cover large islands and the land surrounding it as it can be greater than 50,000
kilometers wide. If melted, they contain enough water to raise sea level about 66m (216 ft.).
Glaciers are smaller and move on average, a little slower but have remarkable ability to carry a huge
volume of water in a stream. A glacier ice forms, where the depth of the snow increases, as the snow
accumulation exceeds, a deep snowpack forms as it is compressed into ice under great pressure it
then begins to flow down the mountain. When the glacier gets to a point where the melting begins
the rate of accumulation dwindles and stops.

The lack of rain that controls the high pressure as this results in rising the air at the equator and then
eventually sinking back and forming a high pressure system which leads in very little precipitation.
2). Distance from an ocean as the hot rising air cools as it drops rain as approaches a mountain. Less
water can be held and that side of the mountain gets rain. The cooler the air that crosses over
mountains is dry, so deserts form on the other side of the mountain range.
3). Rain shadow effect is when moist air rises against high elevations of land and drops water along
the way. This creates a region on the far side of the mountain range that is relatively deficient in
precipitation to the point of forming a rain–shadow desert.
4). Cold ocean currents is because cold water evaporates at a much slower rate than warm water by
forming fewer clouds with much less precipitation.
5). A combination of these four factors are often combined, created, and recorded to form deserts
that have never had precipitation in these

Stories of Our Earth: Causes for Ice Ages and Their...
Will the ice ages happen again? Ice Ages are dramatically landform changing points in time when
the temperatures around the world, including the atmosphere and the surface of the Earth, are
consistently cold for spans of over thousands of years. Ice ages force a glacial period (when thick,
large sheets of ice cover a massive portion of the Earth's northern hemisphere). Studies show that
ice used to cover approximately 30% of the Earth during our last ice age. A point in time can be
classified as an ice age as long there are permanent ice sheets, ice glaciers of size over 50,000 km2.
That's roughly 9 football fields. So technically, we're in the middle of an ice age because we still
have large ice sheets such as Greenland and Antarctica. ... Show more content on Helpwriting.net ...
Changes in land formations during the ice ages happened in different ways, but most of them relate
to the process of glaciation. During the Ice Age, glaciation, the process of being covered by ice
sheets took place over giant land masses and entire continents which is known as "continental
glaciation". As this large scale glaciation took place, changes in land formations occurred, that of
which are uncommon to be formed today. They include moraines, drumlins, kames, eskers, and
Kettle Lakes. Most of the evidence that was discovered has to do with the Earth's geography, the
physical features of the Earth. The ways these glaciers affected the landscape were separated into
three different categories: erosion, transportation and deposition.
Moraines are rocks and debris carried by glaciers, which are large masses of flowing ice and water
that flow because of their heavyweight, and put into areas, especially near where they are rarely
found. From this point, the debris that the moraines consists of can be classified as till, which is
unsorted, randomly arranged material mixed together. This is similar to when sand is washed by sea
tides, and the sand is shaped in to a hill near the shore. Most of these are created by transportation of
the debris and deposition.
There are many different types of glacial moraines including ground, lateral, medial,

Glaciers Are Formed By Ice Erosion
Glaciers are essentially frozen rivers. They are common in the Northern Hemisphere as well as at
high altitude.
Glaciers don't erode quickly, but over a long period of time they can cause drastic changes.
Did you know that Glacial lakes are formed by ice erosion?
The glacier carves out a ditch in the earth and the glacial water melts and is left behind, and when
the glacier is moving, it collects rocks with it.
A Glacier's weight, combined with its gradual movement means that the glaciers can change the
land and make unique land forms. The three processes by which glaciation effects and changes
landscape is erosion, transportation and deposition. Did you know that when water freezes,it gets
bigger and expands, then it will break the rock. This type of erosion is called the freeze thaw. ...

There are two important processes of glacial erosion. The first process is called plucking, Plucking
occurs when cracked and broken rocks are frozen and stuck into glaciers. As a glacier moves over
the landscape, water melts under the glacier and gets into cracks within the underlying bedrock. The
water freezes and melts, weakening the bonds holding pieces of bedrock in place. These pieces of
rock can now be plucked from their rocky base and carried along with the moving glacier.
Glaciers have carved out a number of important geographic

Nature And Mother Nature : Reconnecting With Mother Earth
The glacial erratics represent the beginning of human population of the America's and the beginning
of traditional culture, and the rocks carry with them the essence of the spirit of all those years. In
honour of the truth and reconciliation act, this essay has an ode to healing by walking the land and,
more specifically, reconnecting with Mother earth. I am not a religious person. I am not a spiritual
person even in my own mind. And I do not even know if I believe if there is or is not a god. But I
have always known that the forest and the mountains and the animals are alive as much as I am, and
as an anxious, extroverted, depressed, abused, somewhat autistic person, I have always found more
comfort in the company of a forest than a crowd. I have always been a person who retreats to the
solitude of the forest to find my peace, my happiness, and some kind of connection with something
greater than myself. Despite my strong lack of religious faith or spiritual belief, my connection to
mother nature and my spiritual red roots grew deeply on what I was able to participate in during the
field trip. As I prayed during smudge I had intense vision in a trance which made me sick to my
stomach as I purged myself of the toxins that had entered my spirit both from people and from
having to live in the city with no nearby forest for the last few years. My trances are explained in
detail in the appendices II and III as I feel they are important to my experiential learning. Aside
