Mass wasting occurs when sediment and rock moves from a higher elevation to a lower elevation.

Explanation: Mass wasting is also called slope movement or mass movement. It involves the large movement of rock, soil and debris downward due to the force of gravity. During the process sand, soil, and rocks move down slope as a solid, continuous or discontinuous due to the force of gravity. It may be caused increased slope steepness, increased water, decreased vegetation and earthquakes

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
