(ii) What is a mineral?
Answer:
A mineral is a naturally occurring inorganic substance with a definite chemical composition and crystalline structure, found in the Earth’s crust, used for various purposes in industries and daily life.
(iii) How are minerals formed in igneous and metamorphic rocks?
Answer:
Minerals are formed in igneous rocks through the cooling and solidification of molten magma or lava, which results in the crystallization of mineral components. In metamorphic rocks, minerals form due to the recrystallization of existing minerals under high pressure and temperature conditions, leading to the formation of new mineral compositions.
(iv) Why do we need to conserve mineral resources ?
Answer:
Conserving mineral resources is important to sustainably meet present and future needs. It ensures continued availability for industrial, economic, and societal development while minimizing environmental degradation and depletion of finite reserves.
3. Answer the following questions in about 120 words.
(i) Describe the distribution of coal in India
Answer:
India has a large distribution of coal, mainly in the eastern and central regions of the country. The states of Jharkhand, Chhattisgarh, Odisha, West Bengal, Madhya Pradesh, and Telangana have the largest coalfields. The majority of India’s coalfields are in the northeast of the peninsular plateau, which includes parts of Jharkhand, Chhattisgarh, Odisha, and eastern Madhya Pradesh, and the western part of West Bengal. The southern part of Andhra Pradesh and eastern Maharashtra also have large coal deposits.
India’s coal is mainly found in sedimentary rock formations, with the Gondwana coalfields being the most important. Gondwana coal is about 200 million years old, while tertiary deposits are about 55 million years old. The main resources of Gondwana coal are in the Damodar Valley (West Bengal, Jharkhand), Jharia, Raniganj, and Bokaro. Tertiary coals are in the northeast states of Meghalaya, Assam, Arunachal Pradesh, and Nagaland.
(ii) Why do you think that solar energy has a bright future in India?
Answer:
Solar energy has a bright future in India because of its many potential benefits, including:
- Tropical country: India’s tropical climate makes it a great place for solar energy.
- Rural areas: Solar energy is becoming more popular in rural and remote areas.
- Power plants: Large power plants are being built in different parts of India.
- Environment: Solar energy can help the environment and reduce the need for firewood and dung cakes in rural areas.
- Renewable: Solar energy is a renewable source of energy, unlike other conventional sources that are non-renewable.
- Sunlight: Many parts of India receive sunlight for 300 days a year, which allows for the generation of 20 MW of solar energy per square kilometer.
- Easy to establish: Solar plants are easy to set up in both urban and rural areas.
- Popularity: Solar energy is becoming more popular because it can be used for cooking, heating water, and lighting.
- Clean: Solar energy is a clean and environmentally friendly source of energy that doesn’t produce greenhouse gas emissions.
