Changes take place in the configuration of the earth’s surface due to the physical pressure and chemical processes by endogenetic and exogenetic forces.
Two types of forces work in the formation of the earth’s surface:
1. Endogenetic Forces
2. Exogenetic Forces
Endogenetic forces originate from deep down the surface and work at a very slow speed. By this, mountains are formed and unevenness is created on the earth’s surface. Undesirable incidents also occur by some endogenetic forces like volcanic eruption, earthquake, etc. Exogenetic forces originate above the surface and work right opposite to the endogenetic forces, thereby trying to reduce the relief.
In this process, somewhere they do the work of erosion and somewhere accumulation. In this way, the unevenness of the earth’s surface reduces by exogenetic forces. Thus, these forces are also called ‘Level Establishing Force’. The opposite work of both the forces remains as long as the opposing action of endogenetic and exogenetic forces continue. In this way, it is said that the Earth is the playground of geomorphic processes of two opposing groups.
