Answer:
Option (B)
Explanation:
A rockfall is defined as a type of mass movement process, where the small and large fragments of rocks are weathered and fall down from the top of the cliff under the influence of gravity. It is a process that takes place in a dry condition. This means that it does not depend on the moisture content that could be present in the rock. The rock particles fall down by bouncing and rolling. The base of this rockfall area forms a collection of smaller to larger size rock fragments. This process mainly takes place in the region where the temperature of the area is very high and experiences comparatively less amount of rainfall.
Thus, this type of mass movement is the fastest of all and is not dependent on the amount of moisture content.
Thus, the correct answer is option (B).
The option that gives the type of mass movement that is the fastest and depends upon moist or saturated conditions the least is;
Option B; Rockfalls
To answer this question, let us analyze each of the options.
Option A; Solifluction; This occurs when is the soil becomes saturated and then the wet soil starts to flow down a slope. This alongside creep are the slowest types of mass movement.
Option B; Rockfall; These occur when rock fragments that could be tiny or huge fall down from cliffs that are steep. Thus, this is the fastest type of mass movement as it is not dependent on moist or saturated conditions.
Option C; Rockslides; These are also known as landslides and they occur when numerous amounts of loose rocks get to join with soils and suddenly fall down from a slope.
Option D; Soil Creep; This means a slow movement of soil material down a slope under the Influence of gravity.
Option E; Talus Creep; This is a very slow movement of individual rock fragments individually down a slope.
Looking at the analysis of the options above, we can say that the fastest form of mass movement is Rockfalls.
