INDIA – MINERAL AND POWER RESOURCES
EXERCISES
I. Fill in the blanks with suitable words:
1. The wonder metal of the 20th century is Bauxite (aluminium).
2. The largest producer of gold in India is Hatti.
3. Mica is also called ‘kage bangara’ in Kannada.
II. Answer the following questions in brief:
4. What are the important mineral resources available in India?
Answer: The important mineral resources available in India are iron ore, manganese ore, bauxite ore, mica and gold. In addition to these, energy resources like coal, petroleum and atomic minerals are also produced in the country.
5. Which are the types of manganese ore?
Answer: The main types of manganese ore are Pyrolusite, Psilomelane, Magnatite, Branite and Holyandite.
6. What are the uses of Mica?
Answer: Mica is used in the manufacture of telephones, telegraph, wireless service, glass, colour varnish, artificial rubber, dynamos and chemical industries.
7. Which are the important atomic minerals?
Answer: The important atomic minerals found in India are Uranium, Thorium, Berylium, Lithium etc.
8. What is non-conventional energy resources? Explain their importance.
Answer: Renewable energy sources are solar energy, wind energy, tidal energy, Geo thermal energy, bio-gas etc. are called non-conventional energy sources. All over the world, due to the use of conventional energy sources like coal, petroleum, natural gas and other fossil fuels, the phenomenon of green-house effect and consequent increase in temperature of the earth’s atmosphere is being noticed. This is called ‘global warming’. Population increase, urbanization, industrialization etc. have also led to the increased use of fossil fuels. Due to this, environmental pollution is also increasing. Today, it is essential to reduce the use of such fuels and preserve environmental stability. So the use of non-conventional energy resources is essential in our daily life.
9. Give suggestions of your own to eradicate the power scarcity.
Answer: It has become inevitable in our country to take necessary steps to prevent the deficit in the energy resources. 1.Use of non-conventional resources 2.Giving importance to hydro-electric power generation 3.Use of alternate local energy resources 4.Encouraging the use of non-conventional energy resources 5.Educating the people regarding the reduced use of energy resources 6.Producing energy from solid waste.
Following points also can be done to eradicate the power scarcity.
- Switch off lights, fans, and electronics when not in use.
- Use energy-efficient appliances and LED bulbs, which consume less power.
- Avoid phantom loads by using smart power strips for devices that draw power even when off.
- Reduce water heating needs by taking shorter showers and using less hot water.
- Use public transport, carpool, or cycle instead of personal vehicles to reduce fuel consumption, which also saves energy.

2. Name the states which are establishing wind power stations?
Answer: Tamil Nadu, Maharashtra, Karnataka, Rajasthan and Gujarat are establishing wind power stations in India.
3. Describe the different types of atomic minerals found in India.
Answer: The important atomic minerals found in India are Uranium, Thorium, Berylium, Lithium etc.
a. Uranium: It is distributed in Singhbhum and Hazaribagh of Jharkhand, Gaya of Bihar, in the loamy soil of Saharanapur of Uttar Pradesh, in the sandy coasts of Kerala.
b. Thorium: This can be found in Kerala, Bihar, Tamil Nadu and Rajasthan.
c. Berylium: Berylium oxide is used as a catalyst or ‘moderator’ in reactors producing nuclear energy. India has sufficient deposits of berylium.
d. Lithium: This light metal is obtained from lepidolite and fudomine ores. It is found abundantly in Jharkhand and Madhya Pradesh.
4. Petroleum is called ‘Liquid Gold’. Why?
Answer: Petrol is not only an energy source but also an important raw material. A number of industries have flourished using this as a raw material. Petroleum is a very important energy resource in agriculture, industry and transportation. This is a very precious in both during peace and war. Hence it is called ‘Liquid Gold’.
5 . Which are the types of Mica?
Answer: Based on the chemical composition and colour, mica is divided into many types. They are Muscovite (white), Biotite (black), Phlugovite (brown) lepidotite etc. India has plenty of the best variety, i.e., muscovite.
III. Activity:
1. Show the distribution of minerals on an outline map of India and mark them.
