Question

Brief information on mineral and power resources ​

Answer 1

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.

Types of Minerals:

• On the basis of composition, minerals are classified into metallic and non-metallic types.
• Metallic, minerals contain metals in raw form.
• Metals are hard substances that conduct heat and electricity and have lustre or shine. For example, iron ore and bauxite.
• Metallic minerals are of two types: (a) Ferrous and (b) Non-ferrous.
• Ferrous minerals contain iron ore, manganese, and chromites. Most of the Iron and steel industries and heavy industries depends on this mineral.
• Non-ferrous minerals do not contain iron but may contain some other metals like gold, silver, copper or lead.
• Non-metallic minerals do not contain metals. For example, limestone, mica, gypsum, coal, and petroleum.
• Mining, drilling, and quarrying are the three extraction methods of minerals.
• Mining is the process of taking out minerals from rocks buried under the earth’s surface.
• The process of mining includes two methods: (a) Open cast mining, (b) Shaft mining

( and many more)

Distribution of Minerals:

• Minerals are found in igneous rock, metamorphic rocks and sedimentary rocks.
• Iron ore, nickel, copper minerals are found in igneous and metamorphic rocks.
• Limestone is found in sedimentary rocks.
• Plateau region of India such as Deccan and chota Nagpur plateau provides the rich level of mineral distribution.

Uses of Minerals:

• Some minerals which are usually hard are used as gems for making jewellery.
• Copper is used in almost everything from coins to pipes.
• Silicon is used in almost everything from coins to pipes.
• Aluminum is used in automobile, airplanes, bottling industry, building and in kitchen cookware.
• Silicon is used in the computer industry which is obtained from quartz.
• Mica is used to make electrical appliances and glassmaking industries.
• Iron and steel is used in every indurstry.

Answer 2

Answer:

Minerals are naturally occuring substances that have a definite chemical composition. ... Minerals can be identified on the basis of their physical properties such as colour, density, hardness and chemical property such as solubility.

Power resources:-conventional resources-like firewood, fossil fuel, coal, petroleum, natural gas, hydel power. non-conventional resources-solar energy, wind energy, nuclear energy, geothermal energy, tydal energy, biogas.
