Part of the material of a cliff breaks off and slides down a slope because the material at the base was weakened by wind or water. What type of mass wasting would you classify this as? Fall Creep Flow Slump

## Step 1<br />The problem describes a scenario where a part of a cliff breaks off and slides down a slope due to the weakening of the material at the base by wind or water. This is a description of a type of mass wasting, which is a geological process that involves the movement of soil, rock, and other surface materials downslope under the force of gravity.<br /><br />## Step 2<br />The options provided are different types of mass wasting: Fall, Creep, Flow, and Slump. Each of these represents a different type of movement and process.<br /><br />## Step 3<br />The description of the scenario in the problem aligns with the definition of a "Slump". A slump is a type of mass wasting where the material moves along a curved surface, forming a concave-upward shape. This is consistent with the description of the material breaking off from the cliff and sliding down the slope.
