Colluvial Soils are moved by ____
A
wind
B
water
C
gravity
D
glaciers
Explanation: 

Detailed explanation-1: -Soil transported by the gravitational force is called Colluvium soil. Under the gravitational force, the parent material moves down the slope. Water and wind act as secondary transportation agents responsible for the movement in some cases. Requires little abrasion to round the particles.

Detailed explanation-2: -Soils can be transported and deposited by the action of gravity. The movement, in this case, might be a very small distance. For example, the movement from a steep slope under the action of gravitational force. Talus is a type of colluvial soils that are deposited by gravitational force.

Detailed explanation-3: -Colluvium is heterogeneous, unsorted material of all particle sizes (from boulders to clay) with relatively little abrasion to round the particles. Consequently, colluvium consists of very sharp, angular rock fragments accumulated at the base of steep slopes.

Detailed explanation-4: -Colluvium (also colluvial material or colluvial soil) is a general name for loose, unconsolidated sediments that have been deposited at the base of hillslopes by either rainwash, sheetwash, slow continuous downslope creep, or a variable combination of these processes.

Detailed explanation-5: -Colluvium soil is the type of soil that is transported by gravitational force. The soil that is transported with the help of gravity is known as talus.
