The lithosphere is very important because it is a large reservoir of resources, which are so useful to man. The majority of the material objects which man requires are supplied by lithosphere.
1. The lithosphere serves as a source of minerals. The minerals supply the basic materials required for making a variety of commodities, which man uses daily.
2. The lithosphere is also the major source of fuels such as coal, petroleum and a natural gas. Without these fuels human life, as we know it today, would have been impossible.
3. The lithosphere in combination with the hydrosphere and the atmosphere plays a vital role in the growth of plants and animals. It provides nutrients to the plants. The plants are the source of food for man and all other animals.
