The document discusses minerals, including their definition, formation, distribution, types, and extraction methods. It provides details on key points:
- Minerals are naturally occurring substances with definite chemical compositions that form through geological processes without human interference.
- Metallic minerals contain metals and include ferrous minerals like iron ore and non-ferrous minerals like copper. Non-metallic minerals do not contain metals like limestone.
- Major extraction methods are mining, drilling, and quarrying. Mining removes minerals from underground using open-cast or shaft mining. Drilling extracts oil and gas while quarrying digs out near-surface minerals.
- Asia, Europe, North and South America, Africa,

8th std Social Science Chapter- 3. Mineral and power resources
Minerals are naturally occurring substances that have a definite chemical composition.
Minerals are formed in different types of geological environments, under varying conditions.
Minerals can be identified on the basis of their physical properties such as colour, density, hardness and chemical property such as solubility.
Minerals are distributed in rocks and sea bed also.
Tropical regions are very rich in terms of mineral resources.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. -MINERALS
-A naturally occurring substance that has a definite
chemical composition is a mineral.
-Some minerals are found in areas which are not
easily accessible such as the Arctic ocean bed and
Antarctica.
-Minerals are formed in different types of geological
environments, under varying conditions.
-They are created by natural processes without any
human interference.

-Minerals are formed in different types of geological
environments, under varying conditions.
-They are created by natural processes without any
human interference.
3. -They can be identified on the basis of their
physical properties such as colour, density,
hardness and chemical property such as
solubility.
-Minerals are not evenly distributed over
space.
-They are concentrated in a particular area
or rock formations.
5. -Metallic minerals contain metal in raw
form.
-Metals are hard substances that conduct
heat and electricity and have a
characteristic lustre or shine.
-Examples of metallic minerals are Iron
ore, bauxite, manganese ore etc.
-METALLIC MINERALS
7. -FERROUS MINERALS
-Ferrous minerals like iron ore, manganese
and chromite contain iron.
-NON-FERROUS MINERALS
-A non-ferrous mineral does not contain
iron but may contain some other metal
such as gold, silver, copper or lead.
8. -NON-METALLIC MINERALS
-Non-metallic minerals do not contain
metals.
-Examples of Non-Metallic Minerals are
Limestone, mica and gypsum etc.
-The mineral fuels like coal and petroleum
are also non-metallic minerals.
10. -MINING
-The process of taking out minerals from rocks buried under the
earth’s surface is called Mining.
-TYPES OF MINING
-Open cast Mining
-Shaft Mining
-Minerals that lie at shallow depths are taken out by removing
the surface layer; this is known as open-cast mining.
-Deep bores, called shafts, have to be made to reach mineral
deposits that lie at great depths. This is called shaft mining.
11. -DRILLING
-Petroleum and natural gas occur far below
the earth’s surface. Deep wells are bored to
take them out, this is called drilling.
-QUARRYING
-Minerals that lie near the surface are
simply dug out, by the process known
as quarrying.
12. -DISTRIBUTION OF MINERALS
-Minerals occur in different types of rocks.
-Some are found in igneous rocks, some in metamorphic
rocks while others occur in sedimentary rocks.
-Metallic minerals found in igneous and metamorphic
rocks formations that form large plateaus.
-Iron-ore in north Sweden, copper and nickel deposits in
Ontario, Canada, iron, nickel, chromites and platinum in
South Africa are examples of minerals found in igneous
and metamorphic rocks.
13. -Sedimentary rock formations of plains and
young fold mountains contain non-metallic
minerals like limestone.
-Examples are Limestone deposits of Caucasus
region of France, manganese deposits of
Georgia and Ukraine and phosphate beds of
Algeria.
-Mineral fuels such as coal and petroleum are
also found in the sedimentary strata.
15. -Distribution in Asia
-China and India have large iron ore deposits.
-The continent produces more than half of the
world’s tin.
-China, Malaysia and Indonesia are among the
world’s leading tin producers.
-China also leads in production of lead, antimony
and tungsten
-Asia also has deposits of manganese, bauxite,
nickel, zinc and copper.
16. -Distribution in Europe
-Europe is the leading producer of iron-ore in the
world.
-The countries with large deposits of iron ore are
Russia, Ukraine, Sweden and France.
-Minerals deposits of copper, lead, zinc, manganese
and nickel are found in eastern Europe and
European Russia.
17. -NORTH AMERICA
-The mineral deposits in North America are located
in three zones: the Canadian region north of the
Great Lakes, the Appalachian region and the
mountain ranges of the west.
-Iron ore, nickel, gold, uranium and copper are mined
in the Canadian Shield Region, coal in the
Appalachians region.
-Western Cordilleras have vast deposits of copper,
lead, zinc, gold and silver.
18. -SOUTH AMERICA
-Brazil is the largest producer of high grade iron-ore in
the world.
-Chile and Peru are leading producers of copper. Brazil
and Bolivia are among the world’s largest producers of
tin.
-South America also has large deposits of gold, silver,
zinc, chromium, manganese, bauxite, mica, platinum,
asbestos and diamond.
- Mineral oil is found in Venezuela, Argentina, Chile,
Peru and Columbia.
19. -AFRICA
-Africa is rich in mineral resources.
-It is the world’s largest producer of diamonds, gold
and platinum.
-South Africa, Zimbabwe and Zaire produce a large
portion of the world’s gold.
-The other minerals found in Africa are copper, iron
ore, chromium, uranium, cobalt and bauxite.
-Oil is found in Nigeria, Libya and Angola.
20. -AUSTRALIA
-Australia is the largest producer of bauxite in the
world.
-It is a leading producer of gold, diamond, iron ore,
tin and nickel.
-It is also rich in copper, lead, zinc and manganese.
-Kalgoorlie and Coolgardie areas of western
Australia have the largest deposits of gold.
21. -ANTARCTICA
-The geology of Antarctica is sufficiently well known
to predict the existence of a variety of mineral
deposits, some probably large.
-Significant size of deposits of coal in the
Transantarctic Mountains and iron near the Prince
Charles Mountains of East Antarctica is forecasted.
-Iron ore, gold, silver and oil are also present in
commercial quantities.
22.
23. -Conservation of Minerals
-Minerals are a non-renewable resource.
-It takes thousands of years for the formation
and concentration of minerals.
-The rate of formation is much smaller than the
rate at which the humans consume these
minerals.
-It is necessary to reduce wastage in the process
of mining.
-Recycling of metals is another way in which the
