The solid crust, often known as the uppermost layer of the earth, is known as the lithosphere. It is primarily made up of rocks and minerals, with a thin coating of soil on top. Mountains, plateaus, plains, valleys, and other landforms make up the irregular surface.

The biosphere is the narrow zone of contact where all the three zones namely, lithosphere, hydrosphere and atmosphere interact and form a living zone that supports life. It includes both the biotic and abiotic environments. It extends from the bottom of the ocean to the top of the highest mountain.
