LAB 6 - LANDSLIDES AND MASS WASTING

• Investigate landslide properties

• Relate landslides and wildfires

• Measure angle of repose and compare the angle for different materials

LANDSLIDES

• Different situations create different types of landslides, which are given unique names by geologists.

• Hillside creep, rock fall, slump, etc.
