Mass movement/ Weathering process

Question 1

mass movement is ????

Answer 1

Rapid movements. Slides: A movement of material ‘en-masse’ which remains together until impacting the bottom of a slope. Rockfalls: Slopes must be extremely steep. They are a result of a variety of causes, for example, extreme weathering such as freeze-thaw action may loosen material.

Question 2

Answer 2

a fluid or hardened stream or avalanche of mud.

Question 3

what are sub aerial processes

Answer 3

Sub-aerial processes refer to the processes of weathering and mass movement. Weathering is the breaking down of rock in situ. It can be divided into mechanical and chemical weathering. Mechanical weathering refers to physical processes like freeze-thaw action and biological weathering.
