INDIAN GEOGRAPHY

Detailed explanation-1: -It takes thousands of years for the formation and concentration of minerals. The rate of formation is much smaller than the rate at which humans consume these minerals.

Detailed explanation-2: -New mineral deposits are being continuously created by the Earth but may take millions of years to form. Mineral deposits differ from renewable resources, such as agricultural and timber products, which may be replenished within a few months to several years.

Detailed explanation-3: -Physical and chemical conditions include factors such as temperature, pressure, presence of water, pH, and amount of oxygen available. Time is one of the most important factors because it takes time for atoms to become ordered. If time is limited, the mineral grains will remain very small.

Detailed explanation-4: -Minerals are formed over a period of millions of years in the earth’s crust. They are derived from rocks, which form the earth’s crust. They are of different kinds, for example, salt, coal, petroleum, quartz, bauxite, iron, copper, gold and diamond. They are broadly grouped as metallic and non-metallic.
