Question

Quizplus · Accepted Answer

The hillside shown in the image is exhibiting characteristics of a slump, which is a type of mass wasting event that involves the gradual movement of a block of material along a curved surface. In this case, the material appears to be sliding down the slope in a semi-circular shape. This is supported by the presence of tension cracks at the top of the slope, which are a common feature of slumps. An avalanche involves rapid movement of snow, whereas a debris flow involves a mixture of water and sediment. Solifluction refers to the slow movement of soil due to freeze-thaw cycles and the presence of excess water, and is not a likely explanation for the features seen in the image.
