The document is a summary note for a section on minerals from a science textbook. It begins by recapping that fossil fuels come from once-living things. It then states that minerals come from non-living things and have unique characteristics and qualities. The summary proceeds to list the key characteristics that define a mineral: they are naturally occurring, inorganic, solid substances with definite chemical compositions and crystalline structures. It provides examples for each characteristic. The summary concludes by explaining that crystals in minerals form through either ionic or covalent bonding in orderly repeating patterns.
Oil shale is a sedimentary rock that contains kerogen, which can be heated to produce oil and gas. Mongolia has significant oil shale resources that could provide economic and energy security benefits. Developing oil shale involves technical, economic, environmental and political challenges. In-situ heating methods avoid surface impacts and produce high quality oil. Pilot projects in Mongolia have shown promising results for the quality and quantity of oil produced from local oil shales using in-situ methods. A pre-feasibility study estimated a commercial facility could produce 6,700 tons of oil products per day, creating thousands of jobs and increasing government revenues.

Piece 2:
Many scientists have studied whether vaccines cause autism and they have found no link. Large studies with hundreds of thousands of children have all found that vaccines do not increase the risk of autism. While autism diagnosis has increased over the decades, this is likely because we have learned to recognize it better and the definition has expanded. Herd immunity is also important to protect those who cannot get vaccinated like newborns or people with

Fossil fuels such as coal, oil, and natural gas currently provide over 85% of the energy consumed in the United States and nearly two-thirds of its electricity. Coal is formed from vegetation that died millions of years ago and was compressed over time. Oil is formed from the remains of ancient plants and animals and is refined to make gasoline, diesel, and other products. Natural gas is formed from ancient algae and is used to create electricity, steel, and other materials. Major oil spills like the Exxon Valdez and Deepwater Horizon catastrophes caused environmental and economic damage.
Fossil fuels such as coal, oil, and natural gas currently provide over 85% of the energy consumed in the United States and are expected to continue powering the economy for decades. Coal forms from decayed plant matter that is compressed over millions of years, oil forms from the remains of ancient organisms, and natural gas forms from small aquatic organisms. These fossil fuels are refined and used to power transportation, generate electricity, produce raw materials, and heat homes. However, extraction and transportation accidents can also cause ecological disasters like the Exxon Valdez and Deepwater Horizon oil spills.

This document is the winter 2013 issue of The Planet Magazine, which is the quarterly student publication of Western Washington University's Huxley College of the Environment. It features several articles about environmental policy issues, including stories on the Alberta tar sands and the proposed Keystone XL pipeline, coal exports from Washington state, invasive mussels in Lake Whatcom, and the challenges facing the Washington State Liquor Control Board in regulating the newly legalized marijuana industry under Initiative 502. The magazine is produced and written by students at Huxley College and aims to promote environmental advocacy through responsible journalism.
The oil sands are Canada's third largest proven reserve of crude oil, located in Alberta and Saskatchewan. They contain over 1.8 trillion barrels of bitumen, which is extracted through mining or drilling processes. While oil sands production was only 1.6 million barrels per day in 2011, it is expected to grow significantly in the coming decades to meet global energy demand. The oil sands industry aims to develop the resource responsibly while minimizing environmental impacts through stringent regulation and new technologies.
The document provides information about Alberta's oilsands, including:
- The oilsands deposits are estimated to contain over 1.7 trillion barrels of bitumen. Currently, 175 billion barrels are proven reserves.
- Production is expected to increase from the current 1 million barrels per day to 3 million barrels per day by 2015.
- There are two main methods for extracting bitumen - open pit mining and in-situ recovery using techniques like steam injection or cyclic steam stimulation.
Fossil fuels such as coal, oil, and natural gas were formed from the remains of ancient organisms millions of years ago. Coal forms from dead vegetation that fell into swamps, got buried, and underwent heat and pressure over time. Oil forms similarly from buried plant and animal remains. Natural gas forms from microscopic organisms and is composed primarily of methane. These fossil fuels are important energy sources that are used to generate electricity, fuel vehicles and machinery, and produce other products through refining. Major oil spills like the Exxon Valdez and Deepwater Horizon catastrophes caused environmental damage when crude oil leaked into waterways.
Petroleum, or crude oil, is a fossil fuel formed from the remains of ancient sea plants and animals. It is trapped underground within porous rock formations. Natural gas is also a fossil fuel formed in the same process from the remains of sea life. It is composed primarily of methane and is trapped similarly underground. Both oil and natural gas are nonrenewable resources that are important sources of energy, but their extraction and use can also impact the environment if not properly regulated.

1) Petroleum has been used by humans for millennia originally for fires and warfare. It was exploited in the Middle East between the 8th and 12th centuries from natural oil seeps.
2) The demand for petroleum grew slowly in the 1800s but increased in the late 1800s as whale oil was replaced by kerosene lamps. Coal remained the dominant fuel source until 1940 when petroleum surpassed it.
3) Crude oil and natural gas are mixtures of hydrocarbons that occur naturally underground. Crude oil is the chief source of transportation fuels after refining, while natural gas is used for power generation and manufacturing after processing.
The document discusses investing in oil shale deposits in the United States. It notes that U.S. reliance on foreign oil has decreased to its lowest level in over 20 years due to production from oil shale deposits, with imports down to 40% from 60% a few years ago. The largest known oil shale deposits in the world are in the U.S., with total known reserves of nearly 5 trillion barrels. Investing in finding, extracting, and delivering oil from these large domestic shale deposits is promoted as a way to profit from America's largest petroleum resource. Specific formations like the Bakken in North Dakota and Montana and areas in Texas and Louisiana are highlighted as particularly promising for continued oil and gas production.

The Arctic is estimated to contain 90 billion barrels of untapped oil and three times as much natural gas according to the USGS. However, drilling plans are controversial due to environmental concerns. Norway has approved increased Arctic exploration but limits drilling in some areas until 2010 to protect wildlife and important fishing environments. A new report indicates the Arctic may hold a fifth of the world's undiscovered yet recoverable oil and gas reserves.

Hydraulic fracturing involves drilling wells thousands of feet underground and injecting a mixture of water, sand, and chemicals under high pressure to fracture shale rock formations, allowing trapped oil and natural gas to flow into the well. The fracturing process is repeated several times per well. While concerns exist about potential groundwater contamination from chemicals and large water usage, studies have found zero confirmed cases of contamination and the water and chemical usage is relatively small compared to other industrial uses such as power plants and agriculture. When productive, only a few fractured wells can provide enough natural gas to meet the needs of a large city for many years.
Fossil fuels such as coal, oil, and natural gas are formed from the remains of ancient plants and animals over millions of years. Coal forms from plant remains undergoing heat and pressure over time, with different stages of formation. Oil forms from animal and plant remains in marine environments. Natural gas forms mainly from methane. These fossil fuels are non-renewable and produce carbon dioxide emissions, but are widely used as energy sources for electricity, manufacturing, transportation, and heating. Major oil spills like the Exxon Valdez and Deepwater Horizon have caused devastating environmental damage.

Ernest Rutherford studied the structure of atoms in the early 1900s. He initially believed that atoms were like "loosely packed snowballs" with positive charge and mass evenly distributed. However, when he fired alpha particles at gold foil, some particles bounced back, contrary to this model. This led Rutherford to conclude atoms have small, dense, positively charged nuclei. Later, Niels Bohr built on this work by proposing electrons orbit nuclei in set energy levels, addressing a problem with Rutherford's model. Scientific knowledge is built through collaboration and ideas being tested, scrutinized, and built upon over time.

Designing a school garden process handouts and notesGhaundar
This passage discusses the importance of weeding in the garden. While weeding can seem like a never-ending chore as weeds quickly regrow, it is important for several reasons. Some books and manuals claim that certain weeds, such as green manure and living mulches, can provide benefits. Green manure refers to plants planted specifically to enrich the soil with nutrients and then removed before planting food crops. Living mulches are plants grown among food crops that are intended to suppress other weeds. However, in practice living mulches often do not stay where planted and can outcompete food crops for water and nutrients. Therefore, regular weeding is still important to control weeds and allow food crops to thrive.
Solving the resource problem process handouts and notesGhaundar
The document describes the process of generating ideas to solve a problem. It begins by explaining that generating ideas is an important stage where potential solutions are brainstormed, and this stage is often revised as more is learned about the problem. A sample problem is provided about an asteroid threatening Earth. For this problem, initial ideas are generated like bringing water, a computer, and chickens on a rocket. The document provides templates to help organize ideas into sections like basic country information and resources. Students are directed to add, present, and revise their ideas with feedback to develop an initial plan.
This document outlines 4 potential journal topics: 1) thoughts on group work, 2) a reaction to a green school in Bali, 3) ideas for making a school garden, 4) how to get along with group members of varying abilities. The topics range from personal reflections to proposing ideas and questions around collaboration and school projects.

The Sticky Problems With Tar Sands
Actress Darryl Hannah and NASA scientist James Hansen are just two of
the more than 800 environmental protesters that have been arrested in front
of the White House this week.
The crowd has been demonstrating against the proposed Keystone Pipeline
XL project, which involves building a 1,700-mile (2,735-kilometer) heavy-oil
pipeline from the tar sands of Alberta, Canada, to oil refinement facilities
along the Gulf Coast of the United States.
The decision to allow TransCanada Corp. to go through with the $7 billion
Keystone XL pipeline rests with the U.S. government, and protesters are
hoping to sway Obama to veto the permit.
Aside from the environmental disruption caused by constructing the underground pipeline, the
environmentalists’ opposition to Keystone hinges on the hydrocarbon chemistry of tar sands and how
they’re converted into crude oil.
To understand what tar sands are and why they have a slippery reputation with environmentalists,
here’s a cheat sheet on these unconventional oil fields:
WHAT: Tar sands, also known as oil sands, are a mixture of roughly 90 percent sand, clay and water
and 10 percent bitumen, a thick hydrocarbon liquid. After extracting that 10 percent of bitumen from the
tar-sand mixture, the bitumen can be purified and refined into crude oil.
WHERE: In North America, tar sands are concentrated in the Athabasca Oil Sands in Alberta, Canada.
Because of Canada’s vast oil deposits, it's the top supplier of crude oil to the United States. Saudi
Arabia is the second-largest supplier.
Tar sands are also found in Venezuela and the Middle East.
The proposed Keystone XL pipeline would run from the Alberta tar sands down the middle of the United
States through Montana, North Dakota, South Dakota, Nebraska and Oklahoma, all the way to Texas,
where it will be refined and converted into gasoline. That's longer than the Trans Alaska Pipeline, which
stretches 800 miles. Currently, there are around 55,000 miles of oil pipeline crisscrossing the United
States.
HOW: Squeezing oil out of tar sand is an extremely wasteful process: it takes between 2 and 4 tons of
tar sand and two to four barrels of water to produce a single barrel of oil. Rather than drilling for oil,
enormous shovels carve out open pits in the tar sands, scooping out the greasy interior to be hauled to a
processing facility.
There, the tar sand is combined with water to form a slurry, which forces the sand to sink to the bottom
of the mixture while the bitumen floats to the top. Once the bitumen is extracted, the run-off is piped into
large, stagnant tailing ponds of sand, water, and bitumen impurities.
To make it to the pump, refined bitumen heads to an oil refinery where it’s converted into gasoline. And
since bitumen is a highly viscous “heavy” oil that doesn’t flow as easily as lighter crude, it requires more
processing to facilitate its flow through the oil pipelines.
Overall, mining tar sands, extracting bitumen and converting it to gasoline releases three times more
carbon dioxide than typical oil production. In addition to massive amounts of tar sand needed to extract
4. oil and the carbon emissions generated, the tar sand mining operation takes places in Alberta's boreal
forest, a relatively untouched ecosystem prized for its biodiversity. But the habitat destruction has
threatened the livelihood of various native species, and the Alberta
Water Research Institute is currently
spending $15 million to prevent runoff toxins collected in tailing pools from entering nearby water
supplies.
WHY: As the price of crude oil has risen and relations with the oil-rich Middle East have deteriorated, tar
sands close to American borders have become a more attractive option in the past decade.
Those in favor of the Keystone XL pipeline argue that importing tar sands oil from Canada, a political ally,
will move the country toward more energy independence. However, those opposing the pipeline counter
that reducing reliance on fossil fuels like tar sands oil is the only long-term path toward energy
independence.
HOW MUCH: Tar sands around the world also collectively represent 3 trillion barrels of oil. But a
majority of that tar sand bitumen lies too deep in the earth for recovery with today’s mining technology.
Nevertheless, Canadian tar sands produce more than 1 million barrels of crude synthetic oil every day.
If completed, the Keystone XL pipeline would allow up to 830,000 barrels of crude oil to flow daily to the
Gulf Coast. In June 2011, the U.S. imported just over 2 million barrels of crude oil from Canada every
day, followed by 1.1 million barrels from Saudi Arabia and Mexico each.
The U.S. government should reach a decision on the Keystone XL by the end of the year. The U.S.
State Department has already issued a report on the pipeline’s potential environmental effects and
found “no significant impact on most resources along the proposed pipeline corridor.”
Yet, the report did raise concern about the potential of pipeline leaks in "environmentally sensitive
areas," such as the Ogallala Aquifer, a primary freshwater source for the Plains regions.
NASA scientist James Hansen, who was arrested at the Keystone XL protests in front of the White
House, commented that if the government approves the project, it's "game over" for curbing climate
change.
Meanwhile, in Alberta, enormous dump trucks keep hauling payloads of tar sands to be sifted, sloshed
and siphoned, eventually, into our gas tanks.

6. _______________________________________
______________________________-
Coal is the first resource to study for our science unit. What is it exactly? Well… broadly speaking, oil is
a kind of ____________ that contains a large amount of ___________and does not dissolve (mix with)
in water. (ex. cooking oil, oils in plants)
In the case of _______________, oil is often used to describe crude petroleum, a thick, black modified
form of a special oil found in the upper layers of the earth. (ex. the substance we use to run cars). This
kind of oil is also classified as a fossil fuel because of the way it has been formed. And it is a valuable
energy resource in today’s world.
Let’s learn more…
___________________________?
A fossil fuel is a kind of fuel that is from the ______________ of dead plants and other organisms that
were buried and changed over a very long time (millions of years!). A fuel is kind of material that is
burned to produce power or heat for various uses. (ex. energy for cars, heat for homes).
___________________________
A. _______________– is a rock that contains at least 50 % plant remains. Coal is formed in swamps.
Plants die there and get covered and protected from the air by other plants, water and sediment. As well,
bacteria grow in the dead plants and cause them to break down in a special way that leaves mostly
carbon. Over a very long time, this altered substance gets pushed further down into the warm depths of
the earth. This added pressure and heat also causes changes and eventually a new product is formed:
coal. (see figure 2, pg. 22 in your textbook)
Coal is commonly removed from the ground by _____________ There are various ways. In the case of
_______________ the entire soil and rock above the coal is removed so that the coals is exposed. This
is a good method for coal that is close to the surface. If the coal is too deep, drift mines or slope mines
are made. In this case, an opening is made into the side of a mountain to access the coal.
B. ____________(more) – oil is formed in a very similar way to coal. However, it does not form in
swamps from dead plants. It forms at the bottom of oceans from the buried remains of very tiny marine
(ocean) organisms called plankton. As well, it often gets trapped under rocks. Oil is less dense that
water and tends to move up until hard enough rocks stop and trap it. The rock found right underneath
trapped oil is called reservoir rock.
Oil is commonly removed by drilling. Humans __________a hole from the surface all the way to the
location of the oil. A ____________is inserted and the oil is pumped up and out.
C. ___________________ – natural gas is formed just like oil except that it forms as a gas and not a
liquid.
Natural gas is also removed by drilling and pumping with a pipe like oil.
D. __________________- these fuels are __________natural originally. They are just modified forms of
other naturally occurring fossil fuels like coal or oil. Humans change thinks like coal or oil using special
treatment reactions. For example, _________________is synthetic fuel. It is refined from oil.
7. ___________________________-
It is important to remember that fossil fuels will not last forever. In fact, humans are removing huge
reserves of coal, oil and natural gas every day. A reserve is any fossil fuel amount that can be removed
easily enough to make money in the process. Human predict that coal will run out in 200 years. Natural
gas will only last for 60 more years.
This will be a big problem for the people of the future. What can we do?
1. __________________________ Instead of using coal or oil, we might be able to use methane
hydrates. They are another kind of fossil fuel found on the ocean floor from ice. It may also be better to
use other kinds of resources. Nuclear energy is another important source of electrical energy that is
obtained by a process called fission. It involves the decay of radioactive substances like uranium.
Energy sources that work by fusion may be another solution. Solar energy occurs by fusion reactions in
the sun. It may be possible to use hydrogen located on Earth to produce energy by fusion.
2. ____________________ – another way to conserve fossil fuels is to change _____________ habits
or even way of life. If humans do simple things like turning off the lights, it can make a big difference in
the total amount we use every day

(Chapter 3, Section 1 Summary Note)
Before you learned about fossil fuels. Fossil fuels are one kind of natural resource and they come from
organic things. (living things that died a long time ago)
Now, you will learn about ________________ Minerals are also natural resources but the come from
____________________things. (things that cannot live). As well, they have many other interesting
features and qualities.
What is a Mineral?
A mineral is a _________________ occurring ______________ ________________.It also has an
__________________________ and a ____________________________
Characteristics of Minerals
1. All minerals are formed by _________________ If a human makes something, it can’t be a
mineral.
Ex. salt is formed by seawater so it is mineral. Steel is NOT a mineral because it is made by
humans. (but iron is which steel comes from)
2. All minerals are ____________________ If something is or was living, it can’t be a mineral. It can
have organic elements in it as long there are inorganic elements as well.
Ex. Aluminum is a mineral because aluminum is an inorganic element.
Coal is NOT a mineral because it comes from dead plants.
3. All minerals are either made of a _____________________ or a ____________________ and
thus have a definite chemical composition.
Ex. Salt is a mineral because it is completely made of NaCl compounds and nothing else.
4. All minerals are crystalline solids. Gasses and liquids are NOT minerals.
NOTE- all solids are not necessarily minerals. The first 3 features above must apply!
The Structure of Minerals
All minerals are _________________.. A crystal is a solid with the same kind of atoms or
compounds. These atoms and compounds are also arranged in an orderly, repeating pattern. Ex.
See Figure 2 and 3 on pg. 63,64 in your textbook
Crystals can be formed in 2 ways-
1. _____________________- when hot magma eventually cools later, some of the atoms in it
loose heat energy and move close together in an orderly and repetitive way. As a result, very
large crystals get formed. The type of mineral crystal created depends on what atoms are in
the magma at the time. Ex. Labradorite
2. _______________________- sometimes minerals dissolve in water naturally. Then later the
water evaporates. The remaining ions of the mineral then move close together in an orderly
and repetitive way. As a result, another kind of crystals are made. Ex. salt (sodium chloride)

15. Uses of Minerals
(Chapter 3, Section 3 Summary Note)
Many kinds of minerals are used by people. The following categories outline some of the main kinds of
minerals used and some of their uses
A. Gems-
A gem is a cut mineral that looks very precious. Usually, a gem is a slightly more beautiful
sample among some other more average looking samples for some kind of mineral. A number of
specific properties can often be noted to identify a gem. First, gems are often are clearer, brighter
and/or more colourful than other samples of the same mineral. They can also be polished to a
higher quality than the other samples. For example, amethyst is a gem form of quartz. It just
contains small amounts of iron but other (more common) samples of quartz do not. So it looks
nicer and thus is considered to be a gem. (see Table 2 for gem examples compared to more
common samples)
Gems are often prized which means they have been used and are used in some important
cultural artifacts. For example, many gems are used in jewelry. Then, the gems are called jewels.
The Imperial State Crown of England contains thousands of gems. Diamonds, a kind of gem are
also used in many kinds of jewelry such as wedding rings.
In addition, certain gems can be used as cutting tools especially diamonds. Other gems are
used to produce lasers such as rubies. Some timepieces use quartz crystals to control the
frequency.
B. Ores-
Many other minerals are used in large quantities to make thousands of things in the world. Such
minerals are called ores. They are also obtained from the earth by mining and sold for profit. A good
example is iron. Iron is a single element. It is mined and then sold to make so many things such as
frying pans and even ships. Other minerals may contain useful elements that have to be separated.
Bauxite is mined for the element, aluminum which can be extracted from it by a special refining
process. Then the aluminum is used to make and sell various products including bicycles, pop cans and
even car parts.
C. Vein Minerals – certain minerals can get deposited in spaces between rocks call veins.
Sometimes, these minerals dissolve in fluids and then are carried to certain weak areas of rocks
or empty spaces left by rocks when they collapse. A good example is the mineral, sphalerite
which contains the element zinc. Zinc is extracted and used to coat products with iron to prevent
them from rusting.
D. Titanium – other minerals contain the element titanium including ilmentite and rutile. These 2
minerals are commonly formed when magma cools and solidifies. After mining them, the titanium
is extracted and used for various important products as it is very durable but light. For instance,
racing bicyles as well as suspension parts in cars and even parts of wheelchairs are all made
using titanium.
16. Mineral Identification
(Chapter 3, Section 2 Summary Note)
How can you recognize if something is a mineral or find a mineral already present in
something else? Remember that most minerals share certain characteristics that help to
identify them from other things as follows:
Mineral Appearance – minerals have a particular appearance. For instance, they look
nicer than other similar resources. They could vary in colour (a lot) of even their location
( a little)
Hardness – is a measure of how easily a mineral can be scratched. Some minerals can
be very soft such as talc. Many substance will make scratches in them. Other minerals
are extremely hard such as many diamonds. Few or no other minerals will scratch them.
The Mohs Scale can be used to compare hardness. You can used it to approximate a
hardness value for an unknown mineral. You scratch it with different known minerals.
When you find one mineral can make a scratch but the another mineral cannot than the
unknown mineral’s hardness must be between the hardness for the 2 known minerals.
Luster – the way a mineral reflects light is called luster. Luster can be metallic or non-
metallic. Metal luster comes from minerals that shine a lot like metals. If the mineral does
not shine much, is luster is nonmetallic.
Specific Gravity- is the ratio of a mineral’s weight compared to the weight of an equal
volume of water. It is very similar to a mineral’s density (mass divided by volume). This
number is good for comparing how heavy minerals are.
Streak- A streak is the portion of a mineral that is rubbed off and remains when the
mineral is scratched against some other material. A mineral will only make a streak if it is
softer than the other material. Some minerals will even make streaks against paper such
as graphite. (found in pencils).
Cleavage and Fracture – both of these terms are used to describe the way a mineral
breaks (if even possible). If a mineral breaks into smaller pieces with smooth, flat
surfaces, we say the mineral has cleavage. But if it breaks into pieces that are uneven,
rough or jagged, we say the mineral has facture. Quartz is a mineral with fracture.
Other Properties – some minerals have special other properties that can be useful to
identify them. For instance, certain minerals have magnetic properties such as magnetite.
Some minerals can separate light rays or fizz when acid is added such as calcite.
17. The Rock Cycle
(Chapter 4 – Section 1 Summary Note)
Believe It! # 1 – A rock is actually just a bunch of other things mixed together. Commonly, a rock
contains many different kinds of minerals but it also can contain other things too like volcanic matter,
organic matter and other special natural materials.
Believe It! #2 – A rock never remains the same over time! It is always changing but often very slowly
over time. How the rock changes from one form into another is known as the rock cycle or you could
even say it is a rock process (like our problem solving process!)
General Features of the Rock Cycle-
1. There are 3 main kinds of forms a rock can be in:
a. Metamorphic rock – this rock has been put under a lot of pressure and heat. It can
eventually become magma with enough heat and pressure
b. Igneous rock – when metamorphic rock (or even magma) gets cooled down (for various
reasons), it become igneous rock.
c. Sedimentary rock – Igneous rock can also be exposed to certain elements (ex. weathering
and erosion) that break it down into smaller pieces. Then these smaller pieces can get
compacted into the ground or other medium and become a more dense form. This form of
rock is called sedimentary rock
2. A rock can change from one form into another form by various processes. For example, a
rock could be heated up by magma or it could heated up in a laboratory. Strong winds could blow
at a rock over time causing it to be compacted but water waves could also keep hitting the rock
until it becomes more compacted too.
3. A rock can change to any other form depending on the situation – there is NO single
direction in the rock cycle. Sedimentary rocks could be “loosened” by wind or water to become
eventually igneous rock. Similarly the same sedimentary rocks could get heated up and put under
pressure to become metamorphic rocks. It all depends on the situation the rocks are exposed to.
The Rock Cycle
18. Other Notes-
1. During the rock cycle, matter is never destroyed or created. The rock’s materials are just
recombining with other things to make new forms of matter. OR. Certain rocks are just getting
broken down into separate components. The fact that matter is neither created or destroyed is
called the principle of conversation of matter
2. The rock cycle was first identified and later established by James Hutton, a Scottish scientist.

A. Igneous Rocks-
Igneous rocks are a form or that rocks take when cooled from magma. In other words, under certain
conditions that require extreme temperatures (over 650 degrees Celsius) rocks exist in the form of hot
liquid called magma. This occurs naturally deep below Earth’s surface. When conditions change, the
magma may cool and when it does it changes into a solid rock called an igneous rock. For example,
magma gets pushed out of the earth from volcanoes and flows as lava. The lava then cools once it is
above the Earth’s surface and forms igneous rocks.
Types of Igneous Rocks
1. Intrusive Rocks – Sometimes, (under the right conditions) magma can cool –under- Earth’s
surface and changed into igneous rocks. Such rocks are also called intrusive rocks because they
are formed –under- Earth’s surface. They are only found at the surface when another process
“moves” there such as by erosion. These rocks cool slowly and have large grains (crystals) of
rock.
2. Extrusive Rocks – when magma cools at Earth’s surface (and is really called lava), the igneous
rocks formed are called extrusive rocks. These rocks cool quickly and have very small grains
(crystals) of rocks.
3. Volcanic Glass – sometimes magma cools extremely quickly. As a result, few or not mineral
crystals get formed. This kind of igneous rock is called volcanic glass. Sometimes, gases can get
trapped inside when the new rock form is created causing holes in the rock after the gas
eventually escapes later.
In addition, magma exists as different types depending on what types of minerals are in it. As a result,
the igneous rocks that it changes into when it cools can also be of various types. Basaltic rocks form
from magma that has a lot of iron and magnesium. They are dark in colour. Granitic rocks are formed
from magma that contains a lot of silica (a compound with silicon and oxygen). They are stiff and often
released violently from volcanoes as they are formed. Andesitic rocks have some combination of
minerals from both basaltic rocks and granitic rocks.
B. Metamorphic Rocks-
For a number of reasons, rocks can experience high levels of heat and pressure. (ex. when buried
deeply under Earth or when magma touches them and its hot fluids react with rocks). When this
happens, their physical makeup gets altered by the heat and they change form. The new form of rock is
called a metamorphic rock.
Also note that there are different kinds of metamorphic rocks depending on the rocks that form them and
the heat and pressure conditions. As well, any kind of rock can change into a metamorphic including
igneous rocks, sedimentary rocks and even other metamorphic rocks.
Types of Metamorphic Rocks-
1. Foliated Rocks – sometimes, a high temperature and/or pressure causes other rocks to arrange
into layers as they change into metamorphic rocks. These rocks are called foliated rocks. Their
20. minerals are also pressed together very tightly so that water cannot pass very easily through
them. Examples include slate and gneiss.
2. Nonfoliated Rocks- some metamorphic rocks are not formed as layers. The mineral grains
(crystals) in rocks just get rearranged into some other form to make metamorphic rocks. These
rocks are called nonfoliated rocks. Sandstone and marble are two examples.
C. Sedimentary Rocks-
At other times on Earth, pieces of rocks can get broken off from the main rocks. These loose materials
are called sediments. Then, various processes (ex. the wind, water, ice, gravity, coming out of solution)
can move some of these rock pieces together to become tightly packed. New rocks get formed as a
result and they are classified as sedimentary rocks. These rocks also often form as layers which is a
result of the way they get packed together: often in stacks.
Types of Sedimentary Rocks-
1. Detrital Sedimentary Rocks – these sedimentary rocks are formed by weathering and erosion.
Rocks are broken down by chemical and mechanical actions (ex. by exposure to water or wind)
through a process called weathering. Then, the resulting rock pieces are moved together (Ex. by
the wind or water pushing or picking them up) through a process called erosion. Then, they
become stuck together to form a new solid rock by a process called compaction. Sometimes,
certain large pieces require help to stay stuck together. Sometimes, water and other minerals it
picks up move through open spaces created when large sediments are pushed together. The
water eventually moves on but some of the mineral in the water remain and act like a cement to
help hold the rock pieces together. Such a process is called cementation.
Different rocks are given specific names based on the size and shape of the sediments that form
the sedimentary rocks. For example, conglomerate is formed form round large sediments and
breccia is formed from large sediments with sharp angles. Sandstone is formed from smaller
sediments of almost any kind of mineral but often quartz and feldspar.
2. Chemical Sedimentary Rocks-
These sedimentary rocks form when certain dissolved minerals come out of solution. Rock salt is
a good example. It if formed from compounds containing halogens such as sodium chloride.
Limestone is another good example. It is formed from calcium carbonate that comes out of
solution and is called calcite.
3. Organic Sedimentary Rocks-
Certain organisms (Ex. clams, corals, snails) have hard shells that contain minerals such as
calcite too. When they died, their shells accumulate on the ocean floor and can get packed
together to form rocks such as the rock called coquina. Chalk and coal are another two good
examples or rocks that are formed dead organisms.
