Answer to Question 1

Answer: The gravity force parallel to the surface must be greater than the resisting strength. If the resisting strength of the material is small, then objects move only on a low slope,. If the resisting strength is large, then objects only move on a steep slope. Slope angle is also very important in determining motion, as driving forces increase with increasing slope angle, and resisting strength increases with decreasing slope angle.

Answer to Question 2

Posted another one can you check that one too? Thanks.

Answer to Question 3

Answer: They interrupt cohesion that would otherwise be provided by interlocking mineral grains, making it easier for a mass movement to occur.
