What are the various mobile and mighty exogenic geomorphic agents and what is the prime job they perform ?

It is correct to say that our earth is a playfield for two opposing groups of geomorphic processes.

i. We know that the earth’s crust is dynamic and it moves vertically and horizontally. The internal forces of the earth operating within the earth which build up the crust have also been responsible for the variation in the outer surface of the crust.

ii. The external forces are involved to degrade the landforms built up by the internal forces. The action of the exogenic forces results in wearing down of relief of elevation and filling up of basins on the earth’s surface.

iii. The endogenic forces continuously elevate or build up parts of the earth’s surface and hence the exogenic processes fail to even out the relief variations of the surface of the earth.

iv. Thus variation remains as long as the opposing actions of exogenic and endogenic forces continue. So in this way our earth is a playfield for two opposing groups of processes.
