Climate like any other physical phenomena it is dynamic and not static.
In every part of the world one year, one decade or one century is different than the other.
The change does not only have academic important but its effects in all the forms of life.
Plants, animals, human beings change with changes of climate.
In general, all living species thrive under definite and limit conditions and any great deviation from that will leads to destruction and death of the species.
Ecology: Scientific study of interactions between organisms and their environments which includes Biotic Factors: (Living organisms) , Abiotic Factors: (Nonliving physical and chemical conditions of an environment).
What are the levels of the Ecology?
Ecology has Five Levels.
Individual organism: Single organism in an environment
Populations: Group of individual organisms of same species living in the same area
Communities: All of the organisms that inhabit a particular area make up a community, like coral reef and other organisms live around in the reef
Ecosystems: An ecosystem includes both the biotic and abiotic factors of an area
Biosphere:
Sum of all of Earth's ecosystems, it is an envelope of air, land, and water supporting all living things on Earth. It consists of both the atmosphere and ocean.
Ecologists investigate global issues in the biosphere, including climate change and its effect on living things
The effects have been most dramatic at high latitudes, where multiple processes contribute to decreased surface reflectivity
Changes in temperature are causing species to shift their natural ranges; however, those are unable to move in line with changing temperatures are being put at risk.
The reason for the occurrence of such a huge mass of water on the globe, is still a myth and reality. The reason goes back to the Origin of Earth itself. The exact mode of origin is not precisely known. Scientists assume, both Primary and secondary sources would have given rise to all both air and water on the earth. Two possible sources as internal source (or) external source have been proposed so far. Some of them are attributed towards the theories of origin of the earth.
Oceans are a vast body of salt water that covers almost three to fourths of the earth's surface.
Seas are smaller, found on the margins of the ocean and are partially enclosed by land.
Seawater:
High density, high heat capacity, colder, salty and slightly compressible (its volume decreases under pressure), thus its density increases with pressure.
Why is Ocean Circulation Important?
•Similar to winds in the atmosphere, they transfer significant amounts of heat from equatorial areas to the poles and thus play important roles in determining the climates of coastal regions.
•The ocean circulation pattern exchanges water of varying characteristics, such as temperature and salinity
•ocean currents and atmospheric circulation influence one another.
•in addition, they transport nutrients and organisms
Here you can find the Ocean circulation, as it is happening by natural activities, Coriolis effect will occur due to the wind pattern and changes in the ocean floors.

El Niño is a naturally occurring event in the equatorial region which causes temporary changes in the world climate.
Originally, El Niño was the name used for warmer than normal sea surface temperatures in the Pacific Ocean off the coast of South America.
Now, El Niño has come to refer to a whole complex of Pacific Ocean sea-surface temperature changes and global weather events.
The ocean warming off South America is just one of these events.
Oceanography is the science that studies the oceans along with marine organisms and ecosystem dynamics, ocean currents and waves, plate tectonics and the geology of the sea floor, and the chemical substances and physical properties of the world oceans.

IMPACTS OF CLIMATE CHANGE ON AGRICULTURE AND ALLIED.pptxSGowriShankar5
The Earth's climate has varied vastly in the history. Climate change is the change that can be attributed directly or laterally to mortal exertion that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over similar time ages. The climate sensitivity of agriculture is uncertain, as there is regional variation in rainfall, temperature, crops and cropping systems, soils and management practices. Increase in water and air pollution causing migration of birds and animals as well as decrease in drinking water availability. So, Changes occurred in flowering and fruiting time of crops causing scarcity of fodder in area was affected most impact on Climate Change. The crop losses may increase if the predicted climate change increases the climate variability. Climate change will have its impact on the particulars like Vulnerability to Extreme Events, Impacts on Coastal Areas, Impacts on Biodiversity, Impacts on Pest, Impact of Climate Change on Disease and Crop Loss. The intermittent famines hang seriously the livelihood of billions of people who depend on land for utmost of their requirements. Among the greenhouse effects, CO2 is the predominant gas leading to global warming as it traps long surge radiation and emits it back to the earth surface. The global warming is nothing but heating of surface atmosphere due to emission of greenhouse gases, thereby increasing global atmospheric temperature over a long period of time. There is strong evidence of increase in average global air and ocean temperatures, widespread melting of snow and ice, and rising of average global sea levels. The policies and the mission should ensure the Sustainability of the agricultural development. The need of the hour is strengthening the agricultural policies and programme to address the issues related to impact of climate change.

Impacts of Climate Change on BiodiversityTahaaSaeed
It is a short presentation about the Impacts of climate change on the animals and their diversity. it is a brief explanation of some of the points discussed.
A magnetic survey is a geophysical exploration method used to detect and map variations in the Earth's magnetic field caused by the magnetic properties of subsurface materials. This technique is widely applied in mineral exploration, petroleum exploration, and archaeological studies. Here's a general overview with case study and problems to be solved.
The continental crust covers nearly a third of the Earth’s surface, extends vertically from the Earth’s surface to the Moho discontinuity.
It is less dense than oceanic crust.
Compositionally is dominating by silicate elements
Models for the differentiation of the continental crust shows when and how it was formed
Reconciling the sedimentary and igneous records indicates that it may take up to one billion years for a new crust to dominate the sedimentary record.
The continental crust of the Earth differs from the crust of other planets in the Solar System
Its formation modified the composition of the mantle and the atmosphere
It supports life
And it remains a sink for CO2
Evaluating the composition of new continental crust can provide important clues as to how and when it may have been generated. Which is required understanding the differentiation processes of igneous (granites) and sedimentary rocks
Microfossils are very small remains of organisms 0.001 mm (1 micron) to 1 mm, that require magnification for study.
They are abundant, can be recovered from small samples.
Provide the main evidence for organic evolution through the time
They classified into two groups:
Organic-walled; Acritarchs, Dinoflagellate, Spores and Pollen grains … etc.
Foraminifera Each chamber interconnected by an opening (foramen) or several openings (foramina).
Known from Early Cambrian through to recent times, and has reached its acme during the Cenozoic.
Have a wide environmental range from terrestrial to deep sea and from polar to the tropical region.
Depending on the species, the shell may be made of organic compounds, sand grains and other particles cemented together, or from crystalline calcite.
Inorganic walled; Diatoms, Silicoflagellates, Ostracods, Conodonts, and Foraminifera
Structural geology is the study of the three-dimensional of the rock units with respect to their deformational histories, Structure is spatial and geometrical configuration of rock components.
Structures are classified into two types:
Primary structures.
Secondary structures
Primary structures
Structures that form during deposition or crystallization of the rock, are the result of two processes:
Settling of solid particles from fluid medium in which they have been suspended, in most of the sedimentary rocks.
Crystallization of mineral grains from a liquid in which they have been dissolved as in igneous rocks.
Evaporation is a process by which water changed from the liquid or solid state into the gaseous state through the absorption of heat
It is always related to the loss of water from a free surface over a fixed time interval. Either direct observation or calculation based on the factors involved in the transfer of thermal energy.
One of the fundamental component of hydrological cycle
Essential requirements in the process are
The source of energy to vaporize the liquid water (solar or wind)
The presence of gradient of concentration between the evaporating surface and the surrounding air.
Gold is a transitional metal. In its purest form have reddish yellow color, soft, malleable, and ductile metal.
Atomic number : 79
Atomic mass : 196.9 u
Density : 19.32 g/cm3
Melting point : 1,064 °C
Boiling point : 2,700 °C
Founded in different form associated with different rock type in different tectonic setting.
Discovered from earlier time and used for multi purposes.
Formation of gold
The saying among prospectors that "gold is where you find it" suggests its occurrence is unpredictable, but there is some certain geological environments for the formation.
Because gold is very stable over a range of conditions, it is very widespread in the earth’s crust.
Gold dissolved in warm to hot salty water, the fluids are generated in huge volumes deep in the Earth’s crust as water-bearing minerals dehydrate during metamorphism.
Any gold present in the rocks being heated and squeezed is sweated out and goes into solution as complex ions.
In this form, dissolved gold, along with other elements such as silicon, iron and sulphur, migrates wherever fractures in the rocks allow the fluids to pass.
The direction is generally upwards, to cooler regions at lower pressures nearer the Earth’s surface.
Gold eventually becomes insoluble and begins to crystallize, most often enveloped by quartz.
The association of gold and quartz vein forms one of the most common types of "primary gold deposits".
India
In India, gold mineralization of economic importance is mainly restricted to Archean greenstone terranes of the Dharwar Craton (DC).
The eastern block of the DC has a high favorability for hosting major gold deposits such as Kolar, Hutti, and Ramagiri, whereas the western block hosts only a few smaller deposits such as Gadag, Ajjahanahalli, and Kempinkote.
Gold also discoverrd by GSI in the Singbhum Craton, Aravalli Craton, Bastar Craton and Southern Granulite Terrain (SGT).
India is the second-largest consumer of gold after China.
India currently holds about 558 tones of gold, representing 6.6% of its reserves, (World Gold Council, October 2016).
Kolar Gold Field, Hutti Gold Field and Ramgiri Gold Field are the most important gold fields.
Gold Demand and Use
The largest source of demand is the jewelry industry Gold’s workability, unique beauty, and universal appeal make this rare precious metal the favorite of jewelers all over the world.
Besides jewelry, gold has many applications in a variety of industries including aerospace, medicine, dentistry, and electronics for the manufacture of computers, telephones, televisions...
The third source of gold demand is governments and central banks that buy gold to increase their official reserves.
Private investors there are private investors. Depending upon market circumstances, the investment component of demand can vary substantially from year to year.
The Earth is an unusual planet by having bimodal topography that reflects the two distinct types of crust.
Crust is outer part of the Earth and compositionally is consist tow types, continental and oceanic crust.
The oceanic crust is thin (~ 7 km ), and composed from denser rocks such as basalt , younger.
Whereas the continental crust is thick (~ 40 Km), and composed of highly diverse lithologies, and contains the oldest rocks.
Introduction
Stratigraphy is the study of strata (sedimentary layers) in the Earth's crust, it is the relationship between rocks and time.
Stratigrapher are concerned with the observation, description and interpretation of direct and tangible evidence in rocks to determine the history of the Earth.
The combination of sedimentology and stratigraphy allows us to build up pictures of the Earth’s surface at different times in different places and relate them to each other through the relative ages of rocks
A more modern way of stating the same principle is that the laws of nature (laws of chemistry and physics) that have operated in the same way since the beginning of time.
And thus if we understand the physical and chemical principles by which nature operates, we can assume that nature operated the same way in the past.
Basic principles of stratigraphy
Principle of Uniformitarianism
Principle of Lateral Horizontality
Principle of Superposition
Principle of Cross-cutting Relations
Principle of Inclusions
Principle of Chilled Margins
Correlation
The southern Indian granulite terrane is known for granulite - facies rocks which is formed during the ‘Pan-African orogeny.
The region is composed of Neoproterozoic to Cambrian crustal blocks, dissected by large-scale shear zones (Palghat-Cauvery and Achankovil).
The Palghat-Cauvery Shear Zone System (PCSZ), separates the terrane into two parts, Archean Dharwar Craton in the north and the Neoproterozoic Madurai Block in the south.
The southern margin of this block is defined by the Achankovil Shear Zone.
Geology of the study area
The Achankovil Shear Zone (ACSZ) is major lineament of 8-10 km width and >100 km length.
The rocks in the zone display a prominent NW-SE trending foliation with steep dips to southwest.
Estimation of pressure and temperature (P-T) of this lithology was first carried out by Santosh (1987) based on conventional geothermometers and mineral equilibrium, that gave 700-800◦ C at 5.5-7.0 kbar.
Later study done by Nandakumar and Harley (2000) which is slightly higher 925 ± 20◦ C at 6.5-7.0 kbar .
3.1. Grt- Opx- Crd Gneiss
The Grt-Opx-Crd gneiss is a coarse-grained, granulite-facies rock with a probable pelitic protolith.
The mineralogy of a representative sample (KR19-5G1) is plagioclase (30-40%), ortho-pyroxene (20-30%), garnet (10-20%), K-feldspar (10-20%), quartz (5-10%), and cordierite (2-5%) with accessory of biotite, spinel, and sillimanite (Fig. 2a).
Garnet is very coarse-grained (3-6 mm) ,subidioblastic, and contains numerous fine-grained inclusions of sillimanite (0.05-0.2 mm), biotite (0.05-0.4 mm), spinel (0.05-0.1 mm), and quartz (0.05-0.1 mm).
The most significant feature of this rock is the direct contact relation of fine grained spinel and quartz (Spl + Qtz), which occur only as inclusions in garnet.
Spl + Qtz association has been regarded as one of the indicators for decompression at UHT conditions. This is the first finding of such an assemblage from the ACSZ.
Introduction
Petrophysic of the rocks
It is the study of the physical and chemical properties of the rocks related to the pores and fluid distribution
Porosity, is ratio between volume of void to the total voids of the rock.
Permeability, is ability of a porous material to allow fluids to pass through it.
Electric, most of the sedimentary rocks don’t have conductivity.
Radiation, clay rocks have 40K, radiate alpha ray.
Hardness, it depends on the cementing material and thickness of the sediments.
WELL LOGGING
The systematic recording of rock properties and it’s fluid contents in wells being drilled or produced to obtain various petrophysical parameters and characteristics of down hole sequences (G.E Archie 1950).
The measurement versus depth or time, or both, of one or more physical properties in a well.
These methods are particularly good when surface outcrops are not available, but a direct sample of the rock is needed to be sure of the lithology.
A wide range of physical parameters can be measured.
In some cases, the measurements are not direct, it require interpretation by analogy or by correlating values between two or more logs run in the same hole.
Provide information on lithology, boundaries of formations and stratigraphic correlation.
Determine Porosity, Permeability, water, oil and gas saturation.
Reservoir modeling and Structural studies… etc.
Types of Well Logging
Logs can be classified into several types under different category
Permeability and lithology Logs
Gamma Ray log
Self Potential [SP] log
Caliber log
Porosity Logs
Density log
Sonic log
Neutron log
Electrical Logs
Resistivity Log

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. INTRODUCTION
• Climate like any other physical phenomena it is dynamic
and not static.
• In every part of the world one year, one decade or one
century is different than the other.
• The change is not only has academic important but it effect
in all the forms of life.
• Plants, animals, human beings are change with changes of
climate.
3. • In general all living species thrive under definite and limit
conditions and any great deviation from that will leads to
destruction and death of the species.
• Ecology: Scientific study of interactions between
organisms and their environments which is include Biotic
Factors: (Living organisms) , Abiotic Factors: (Nonliving
physical and chemical conditions of an environment).
• What is the levels of the Ecology?
4. Ecology have Five Levels.
1. Individual organism: Single organism in an environment
2. Populations: Group of individual organisms of same species living
in the same area
3. Communities: All of the organisms that inhabit a particular area
make up a community, like coral reef and other organisms live
around in the reef
4. Ecosystems: An ecosystem includes both the biotic and abiotic
factors of an area
5. 5. Biosphere:
• Sum of all of Earth's ecosystems, it is envelope of air, land, and
water supporting all living things on Earth. It consists of both
the atmosphere and ocean.
• Ecologists investigate global issues in the biosphere,
including climate change and its effect on living things
• The effects have been most dramatic at high latitudes, where
multiple processes contribute to decreased surface reflectivity
• Changes in temperature are causing species to shift their natural
ranges; however those are unable to move in line with changing
temperatures are being put at risk.
6. Important cycles of the biosphere:
• Carbon cycle
• Nitrogen cycle
• Oxygen cycle
• Phosphorus cycle
• Sulfur cycle
• Water cycle
• Rock cycle.
7. The Carbon Cycle
• Carbon is part of all living things, also a part of the ocean, air,
and even rocks.
• Because the Earth is a dynamic, carbon does not stay still. It is
on the move.
• In the atmosphere, carbon is attached to some oxygen forming
CO2
.
• Plants use CO2 and sunlight for photosynthesis, when they died
and buried may turn into fossil fuels like coal and oil.
• Humans burn fuels, carbon enters the atmosphere as CO2.
• Carbon dioxide is a greenhouse gas, that keep the Earth worm,
But humans have increased the amount of CO2 by about 30%
more than what was in the 150 years ago.
8.
9. When the climate change what will happen
for:
• Forest productivity and agriculture.
• Food security
• Migrated birds
• Micro organism and soil.
10. Climatic change and forest productivity
• Forests sustain over 50% of the Earth’s species, regulate climate
through carbon storage, and protect watersheds.
• When the forests changing, due to climate change, Some
species will fare better, others worse.
• Warmer temperatures result in Longer growing seasons and
Shorter winters
• Altered precipitation Increased variability more extreme events
• Changes in forest composition & reduce productivity.
• Forest pests, diseases, Wildlife and Habitat… And more
11.
12. • Climate change adaptation is critical for agriculture and food security
• For any particular crop, the effect of increased temperature will
depend on the crop's optimal temperature for growth and reproduction
• In some areas, warming may benefit the types of crops that are
typically planted there but if the higher temperature exceeds a crop's
optimum temperature, yields will decline.
• Higher CO2 levels can affect crop yields However, other factors, such
as changing temperatures, ozone, water and nutrient content, may
counteract these potential increases in yield.
• More extreme temperature and precipitation can prevent crops from
growing, EX: corn
13. Extreme weather events have caused significant yield reductions in
some years. Source: USGCRP (2009)
14. International Impacts
• Climate change is very likely to affect food security at the global,
regional, and local level.
• It can disrupt food availability, reduce access to food, and affect
in food quality and prices.
• For example, projected increases in temperatures, changes in
precipitation patterns, changes in extreme weather events, and
reductions in water availability may all result in reduced
agricultural productivity.
• Stressors such as population growth may magnify the effects of
climate change on food security.
15. Migrated birds
• Some can be as long as 20,000 miles per year and Higher
than Mt. Everest by store a special high-energy (fat) before
the trip.
• They may shift altitude to find the best wind.
• Why they migrate? is for food and a safe place to breed.
• Migration is affected by food supply wind and oceans
currents.
17. Threats To Migratory Birds
• Climate change is causing shifts in geographic ranges of birds
and their habitat locations.
• Bad weather influence fall migration for birds in the higher
latitudes, these birds arrive later, breed later, molt later and
leave later.
• Plants and other organisms that make up common habitat types
respond to the change and that lead to changes in the structure
and function of ecological communities.
• Affecting the availability of food needed to raise their young.
• Habitat destruction affects staging posts handicap their ability to
re-fuel.
18. Main threats to migratory bird species
Sources: Shoo et al., 2005
19. Plants and animals
Plants and animals can reproduce, grow and survive only within specific
ranges of climatic and environmental conditions. If conditions change
beyond the tolerances of species, then they may respond by:
1. shifting the timing of life-cycle events (e.g., blooming, migrating).
2. shifting range boundaries (e.g., moving poleward) or the density of
individuals within their ranges.
3. changing morphology (e.g., body or egg size), reproduction or
genetics.
4. extirpation or extinction.
20. The micro organism and soil
• Climate change will contribute on soil microbial communities
and associated ecological processes.
• Micro-organisms adapt more quickly than plants and macro-
organisms which means they are ideal bioindicators of the
impact of sources of environmental stress on the functioning of
ecosystems.
• The soil contains a huge number of micro-organisms that are
responsible for many of its vital functions and consequently, its
health.
21. Change in Phenology
• Phenology – the timing of seasonal activities of animals and plants –
is perhaps the simplest process in which to track changes in the
ecology of species in response to climate change.
• Observed phenological events include leaf unfolding, flowering, fruit
ripening, leaf colouring, leaf fall of plants, bird migration, chorusing
of amphibians, and appearance/emergence of butterflies.
• Although phenological network studies differ with regard to regions,
species, events observed and applied methods.
• Changes in spring and summer activities vary by species and by time
of season. Early-season plant species exhibit the strongest reactions
22. Direct and indirect effects of climate change on soil microbial and soil
microbial-plant interactions
23. Changes in species distributions and abundances
Many studies of species abundances and distributions corroborate
predicted systematic shifts related to changes in climatic regimes, often
via species-specific physiological thresholds of temperature and
precipitation tolerance. Habitat loss and fragmentation may also
influence these shifts. Empirical evidence shows that the natural reaction
of species to climate change is hampered by habitat fragmentation and/or
loss.
However, temperature is likely to be the main driver if different species
in many different areas, or species throughout broad regions, shift in a
co-ordinated and systematic manner. In particular, some butterflies
appear to track decadal warming quickly
Whereas the sensitivity of tree-line forests to climate warming varies
with topography and the tree-line history
24. So what will be the mitigation?
• Societies have a long record of managing the impacts of
weather and climate related events.
• Reduce or prevent emission of greenhouse gases.
• Using new technologies and renewable energies.
• Changing management practices or consumer behavior.
• Protecting natural carbon sinks like forests and oceans, or
creating new sinks through green agriculture are also
elements of mitigation.
25. CONCLUSION
• Climate is dynamic phenomena
• Industrials Human activities increased the concentration of
the CO2 and other green house gases which is change the
climate more than the normal rate.
• Result in negative responses of the biosphere, less productivity
of agriculture, Threats of soil , animals and other living forms
of life.
• To reduce the risk we have to reduce or prevent emission of
greenhouse gases.
Biosphere can be pictured as an "envelope" of air, land, and water supporting all living things on Earth. It consists of both the atmosphere of several kilometers higher, oceans to a depth of several kilometers.
Ecologists investigate global issues in the biosphere, including climate change and its effect on living things
Closed system-- all of the chemicals in the living and nonliving things of the biosphere come from within the system.
An exception to this rule is meteorites, which add material to the Earth
Movement and storage of nitrogen (N) through the atmosphere, hydrosphere, biosphere and geosphere of the Earth system.
Plants use carbon dioxide and sunlight for photosynthesis so carbon becomes part of the plant and when they they died and are buried may turn into fossil fuels made of carbon like coal and oil.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But humans have burned so much fuel that there is about 30% more carbon dioxide in the air today than there was about 150 years ago, and Earth is becoming a warmer place. In fact, ice cores show us that there is now more carbon dioxide in the atmosphere than there has been in the last 420,000 years

Agriculture and fisheries are highly dependent on the climate. Increases in temperature and CO2 can increase some crop yields in some places.
For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.
Birds generally wait for good weather to migrate
The role of micro-organisms in relation to the functioning of the soil ecosystem is fundamental.
Soil:
Product of abiotic forces (water, wind, etc) and actions of organisms on the rocks and minerals of the Earth's crust
Structure and chemical makeup of soil and rock affect types of plants able to grow, affecting the other organisms that can exist there
The soil contains a myriad of micro-organisms that are responsible for many of its vital functions and, consequently, its health.
Direct and indirect effects of climate change on soil microbial and soil microbial-plant interactions: What lies ahead?
Protecting natural carbon sinks like forests and oceans, or creating new sinks through silviculture or green agriculture are also elements of mitigation.
