GEOG 1113L Lab 6: Mass Movement
Lab 6: Mass Movement
GEOG 1113L – Introduction to Landforms Lab
I. Erosion Due to Gravity
1. What is mass movement and what is the ultimate purpose of it?
Mass movement is a natural process that plays a huge role in the shaping of the earth. In this
process, gravity makes movement push downward. Soil and rocks will move downward until the
slope is stable. This movement helps create landscapes despite its affect on human populations
2. What is the angle of repose?
An angle of response is the steepest angle at which a material will stay stable without collapsing
or sliding downward.
3. Which of the following does not impact the angle of repose?
A. Moisture level
B. Weight
C. Color
D. Shape
E. Size
4. What factors increase the chance of a landslide?
5. __Creep____ is a slow form of mass movement that involves the downhill movement of soil.
Bent __tree_trunks___ may be evidence of this type of mass movement.
II. Types of Mass Movement

type of mass movement each of the 10 pictures below shows. Highlight the appropriate answer.
,1. Which type of mass movement is shown in the picture above?
