(a) Minerals containing iron are called ferrous minerals, e.g., iron ore and manganese. Minerals which do not contain iron are called non-ferrous minerals, e.g., bauxite, lead and gold. (b) Conventional sources of energy are generally exhaustible and polluting, e.g., firewood, coal and petroleum. NoRead more

Mineral resources need to be conserved because they are limited. It takes billions of years for them to be replenished in nature. Continued extraction of ores leads to increasing costs of extraction and a decrease in quality as well as quantity. For more answers visit to website: https://www.tiwariaRead more

The distribution of coal in India is more abundant on the eastern side of the country. In India, coal occurs in rock series of two main geological ages—Gondwana and tertiary. While Gondwana coal is about 200 million years old, tertiary deposits are approximately 55 million years old. The major resouRead more
The distribution of coal in India is more abundant on the eastern side of the country. In India, coal occurs in rock series of two main geological ages—Gondwana and tertiary. While Gondwana coal is about 200 million years old, tertiary deposits are approximately 55 million years old.
The major resources of Gondwana (metallurgical) coal are located in the Damodar valley (West Bengal, Jharkhand), Jharia, Raniganj and Bokaro.
The Godavari, Mahandi, Son and Wardha valleys also contain coal deposits. Tertiary coals occur in the north-eastern states of Meghalaya, Assam, Arunachal Pradesh and Nagaland.
Being a tropical country, India has an abundance of sunlight. Hence, there are huge possibilities of tapping solar energy. Solar energy is a non-conventional source of energy, but it is gaining popularity in rural and remote areas whose households’ dependence on firewood and dung cakes is reduced asRead more

Solar energy is a non-conventional source of energy, but it is gaining popularity in rural and remote areas whose households’ dependence on firewood and dung cakes is reduced as a result. This in turn helps in conserving environment and ensuring an adequate supply of manure in agriculture.
