Fill in the blanks:
(1) In India, _________ and __________ states having the highest iron ore deposit.
Ans: Jharkhand, Orissa and Karnataka.
(2) Bauxite is produced from _________ metal.
Ans: Aluminium.
(3) Mica is also called _________________ in Kannada.
Ans: kage bangara.
Answer the following questions:
(1) What are the important mineral resources available in India?
Ans: Minerals are the most important natural resources. Minerals are available along with rocks on the surface of the earth. Among them, iron ore, manganese ore, bauxite ore, mica and gold are very important.
- Iron ore: Iron ore is the most important Ferrous and Metallic minerals. Of the total value of minerals production in the country, iron ore constitutes about 20%. India ranks 6th in the world as far as iron ore deposits are concerned.
- Manganese Ore: Manganese is the most important of the Ferro-allied ores mined in India. Manganese is used in the manufacture of steel. It is also used in the manufacture of chemical and electrical equipment and colored glass.
- Bauxite ore: Bauxite is the important ore of aluminium. It is mixed with sand and iron oxide. Being brownish yellow and grey in colour, bauxite is sticky like clay in nature. Bauxite has about 60-70% of aluminium oxide and by melting this, aluminium metal is obtained. Since aluminium is used in various types. It is called the Wonder Metal of the 20th century. Bauxite is mainly used in the production of aluminium metal. India has huge bauxite deposits and also self-sufficient in aluminium production. India ranks 5th in the world in bauxite deposits.
- Mica: Mica is a very large important non-Ferrous mineral. India is in a leading position in having deposits of mica and in the manufacture of mica plates. Mica is transparent, heat resistant, shiny silicate mineral. Mica has some qualities; the important among them are insulation and elasticity. It is used in the manufacture of telephones, telegraph, wireless service, glass, colour varnish, artificial rubber, dynamos and chemical industries. Mica is also called „kage bangara‟ in Kannada.
- Gold Ore: Gold is a valuable metal, and has been popular for ages. Gold is used as a standard in fixing the value in the international money market. India has insignificant gold deposits.
(2) Which are the major states producing manganese in India?
Ans: Orissa, Karnataka, Madhya Pradesh and Maharashtra are the important manganese producing states. In addition, Bihar, Chattisgarh, Rajasthan, Punjab and Goa also produce manganese ore.
(3) Mention the types of iron ore produced in India.
Ans: Based on the metal and impurities content, iron ore is classified into four types:
a) Magnetite
b) Hematite
c) Limonite
d) Siderite
(4) Which are the important energy resources of India? Describe them.
Ans: Power resources are essential for the economic development of the country. Conventional power resources are those which can get exhausted. Example: coal, petroleum, atomic power etc. Non-conventional power sources are those which are not exhaustible. Most important of them are solar power, wind power and hydro-electric power.
- Coal: In India, the most important power resource is coal. India ranks third in the world in the production of coal. It is said that millions of years ago, the earth was covered with thick dense forests, and these forests gradually buried in the layers of the earth and converted into coal due to heat and pressure. Coal is not only an energy source, but also used in the manufacture of insect repellants, explosives, artificial fibre, artificial rubber, plastic, chemical fertilizer etc. Coal being an important mineral product with multiple uses, it is called “Black Diamond”.In India, coal deposits are widely distributed in the Damodar river valley. Jharkhand and Chattisgarh are the states producing the largest amount of coal.
- Petroleum: It is believed by scientists that petroleum is the product of fossils of ancient living beings. Petroleum pumped out of the earth is a mixture of various materials and is called Crude Oil. This is purified in refineries to produce gasoline, petrol, diesel, kerosene etc. 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 very precious both during peace and war. Hence it is called „Liquid Gold‟.
- Atomic minerals: India plenty of atomic minerals. Atomic power is generated using these atomic minerals. Atomic power decides the status and might of a nation. Atomic power was used only for a country‟s defence in the earlier days. But today, it is being widely used for power generation. The important atomic minerals found in India are Uranium, Thorium, Beryllium, Lithium etc.
- Non conventional energy resources: Renewable energy sources are solar energy, wind energy, tidal energy, Geothermal energy, bio-gas etc. are called non-conventional energy sources.
(5) What are non-conventional energy resources? Explain their importance.
Ans: Renewable energy sources such as solar energy, wind energy, tidal energy, Geothermal energy, bio-gas etc. are called non-conventional energy sources. Importance:
- These energy resources are renewable.
- These resources cause less pollution.
- Non conventional energy resources are eco friendly.
- They are easily available in nature.
(6) Give suggestions of your own to eradicate the power scarcity.
Ans: Due to the major use of all types of energy resources there is a decline of energy resources and now it has become a huge problem. The following measures should be taken to eradicate power scarcity.
- Use of non-conventional resources,
- Giving importance to hydro-electric power generation,
- Use of alternate local energy resources
- Encouraging the use of non-conventional energy resources,
- Educating the people regarding the reduced use of energy resources,
- ● Producing energy from solid waste.
