Rocks and Minerals​


 


The earth’s lithosphere is made up of land and the hard crust beneath it. The lithosphere is not homogeneous but is made up of many types of rocks. ​

 

Resources in the earth’s crust include minerals, ores, mineral oil and other fuels, rocks, water, elements, etc. ​

 

Minerals and ores Mineral wealth has an important place among natural resources. Minerals are formed by various processes taking place in the environment. ​

 

The rocks on the earth are mainly made of minerals. These minerals can be obtained by mining. Only a few metals like, for example, gold, silver, copper, platinum and bismuth occur in the free state in nature. ​

 

A majority of the metals occur in the form of compounds. Minerals that contain a high proportion of metal are called ores. ​
