Question

Which of the following is the slowest of all types of mass movement?

A) landslide
B) slump
C) rockfall
D) solifluction
E) earthflow

Answer 1

Solifluction is the slowest type of mass movement among the given options, characterized by the slow movement of water-saturated soil due to freezing and thawing.

Step-by-step explanation:

The slowest type of mass movement among the given options is solifluction. Solifluction is a slow movement of soil or regolith due to the freezing and thawing of water-saturated soil. It typically occurs in cold environments, such as high-latitude regions and alpine areas, where the ground remains frozen for a significant part of the year. Solifluction can lead to the downhill movement of soil, resulting in the formation of terracettes or solifluction lobes.
