Read the below questions carefully and answer the given questions:Our country is also considered very rich in terms of mineral wealth. It is estimated that the country accounts for one fourth of the total iron ore reserves in the world. There are also huge deposits of manganese, a major mineral used in the iron and steel industry. There are also abundant reserves of coal, limestone, bauxite and mica in the country. But non-ferrous minerals such as zinc, lead, copper and gold are in very limited quantities. The sulfur reserves in the country are almost nil, while sulfur is the mainstay of modern chemical industry. We also have plenty of water power resources and nuclear minerals. Their use as a power tool is increasing rapidly due to their power efficiency and very little tampering with the environment. For this reason, solar energy is also being used as a power tool. Solar energy is the priceless power store of God. Its use will increase rapidly as a source of power in the future.(a) What is the contribution of minerals to the national economy?(b) Why is solar energy called the source of future energy? |

Answer» (a) Minerals have great importance in the national economy. The following facts will make it clear.
(b) Coal and mineral oil are exhaustive resources. There will come a day when the people of the world will not get enough energy from them. Their stores must have been exhausted. Unlike then, sun energy is a never-ending means. This gives a tremendous amount of energy. When the reserves of coal and mineral oil are exhausted, then power will be obtained and we will be able to do it easily with our domestic work and plants.
