Chapter: 9th Social Science : Geography : Lithosphere – I Endogenetic Processes

Spheres of the Earth

Spheres of the Earth

Earth’s surface is a vast area of 510 million sq.km, where four spheres of the Earth interact. The abiotic spheres are the lithosphere, atmosphere and hydrosphere. The biotic sphere is the biosphere. Together, these spheres constitute the planet, Earth.

This topic 'lithosphere' has been bifurcated for the sake of convenience. It is divided into Endogenetic processes (Internal processes) and Exogenetic processes (External processes). This lesson deals with the Endogentic processes in detail, the next lesson will deal with the Exogenetic processes.
