Types and Causes of Mass Wasting/Mass Movement of Rocks

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.

Reading Causes of Soil Erosion Geology

Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.

Sediment and mining NIWA

Open cut mining is the most economical means of mining; it removes the minerals closest to the surface which are easiest to extract, but also exposes the largest area of the underlying soil to erosion. The dumping of 'overburden' can form unvegetated hills that are a source of leachate and sediment, which may end up in waterways.
