Two processes of slow mass wastingQuestion 1AnswerA.Mudflow and earthflowB.Slumping and creepC.Solifluction and soil creep

The two processes of slow mass wasting are:

1. Slumping: This is a type of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. The movement is characterized by sliding along a concave-upward or planar surface.

2. Soil Creep: This is the slowest form of mass wasting. The downslope movement of soil or rock fragments on a slope is so slow that it is difficult to observe. The movement is caused by the expansion and contraction of soil due to freezing and thawing, or wetting and drying.

2. Creep: This is the slow, downward progression of rock and soil down a low grade slope; it can also refer to slow deformation of such materials resulting from prolonged pressure and stress. Creep may appear to an observer to be continuous, but it really is the sum of numerous minute, discrete movements of slope material caused by the force of gravity.
