Most destructive kind of mass movement.

Question:

Most destructive kind of mass movement

a. Slump

b. Mud-flow

c. Landslide

d. Creep

Most destructive kind of mass movement is Landslide

Explanation:

Landslide are the form of mass wasting, which results in downward movement of soils and those rocks which because of the gravitational force. This landslide is made up of five other phases like falls, topples, slides, spreads and flows etc. when these landslides occur inside the submarine leads to tsunamis which results in the damage in coastal areas. Most of the mass movements occurs due to the weathering, or can say erosional debris cover on the slope which are prone to mass movement

i think the miocene epoch spans the time from 23 million to 12 million years ago.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
