Mass Movements

by Tim Gault

​

At the end of this lesson you will be able to:

Describe and recognized four types of mass movements - slump, creep, rockslides and mudflows and know the force that initiates them.

Multiple Choice

• erosion

• weathering

• mass movement

• soil formation

Multiple Choice

Which one of the following factors contribute greatly to mass wasting?
