What is Mass Wasting/Mass Movement of Rocks? Mass wasting can be defined as a geomorphic process. A geomorphic process is a natural course of weathering, erosion and deposition that causes alteration of the surface materials and landforms of the earth. Mass wasting is also known as slope movement or mass movement. It can be …
