What is the name of moving fields of angular blocks which are formed by gravity and the freezing-thawing cycle? A. Scree B. Talus C. Bedrock slumps D. Bedrock slides E. Rock glaciers

Option (E)

Explanation:

The Rock glaciers are a type of landform that is formed due to the downward motion of angular blocks under the influence of gravity and the continuous cycle of freeze and thaw method. It mostly occurs in the steep slopes where the soil particles and the rock materials are prone to landslide. Here, the materials are mixed and covered with ice. This also occurs in the region where the permafrost layer undergoes creeping.

This downward motion of ice erodes the soil particles and carries with them further, from the site of talus cone or moraines and extends outward.

Thus, the correct answer is option (E).
