3Mass Wasting/Mass Movement The process by which soil and rock move down-slope.
4Erosion;the process by which natural forces move weathered rock & soil from one place to another.Gravity
5The material moved by erosion is called SEDIMENT. This may include pieces of rock or soil.
6Mass movement happens when gravity moves sediment downhill Mass movement happens when gravity moves sediment downhill. Mass movement can be rapid or slow and is caused by gravity.
7Landslides are the most destructive of the four types of mass movement Landslides are the most destructive of the four types of mass movement. Landslides happen when rock & soil slides quickly down steep slopes.
8This is a picture of a landslide. A type of mass wasting.
