2) What is regolith and how does it relate to mass wasting
3) Describe the influence of water in mass wasting and how it can change the physical properties of material.
4) What is meant by the term natural angle of repose and what controls this angle for various material in nature.
5) Be able to solve for shear force and normal force involving an inclined surface

10) Know that acceleration due to gravity is 9.8m/s2
11)Understand how the following contributes to the formation of unstable slopes and why:
a. overloading a slope d. removal of slope’s toe
b. water e. shale
c. dip of bedrock f. removal of vegetation
12) Understand the mechanism of soil creep and cite a variety of observable phenomena that indicate slow downhill movement.
13) Differentiate between each of the following forms of mass movement and recognize where each is likely to occur:
a. solifluction e. slump
b. mudflow f. rock/debris slide
c. earthflow g. lahars
d. creep
14) Know the four factors used to classify or determine the type of mass wasting that has occurred
