Answer:
In the previous articles, we were discussing various types of endogenic and exogenic processes. We have also seen that erosion and deposition are some of the exogenic processes. In this post, we are dealing with the geomorphic agents – running water and groundwater, which causes erosion and deposition. They form various erosional (destructional) and depositional (constructional) landforms.
Even though we are considering the erosional and depositional activities and their landform creation, it should be kept in mind that they are always aided by weathering and mass movements. There are some other independent controls like (i) stability of sea level; (ii) tectonic stability of landmass; (iii) climate etc. which influence the evolution of these landforms.
