What are the factors causing soil creep?

Give the factors that cause soil creep.

Answers

Maurice
(i) Freezing of soil water expands the spaces between soil particles. Once the water thaws/warms,the particles fall by gravity and may shift position downslope.Moisture acts as lubricant to soil particles causing their movement downslope.

(ii) Temperature change causes soil particles to expand and contract, hence they shift position downslope.

(iii) Human activities and the action of burrowing animals may cause the removal of soil on the lower part of the slope. This has a trigger effect on soil particles on the upper part of a slope which may then shift downslope.

(iv) Moisture or rainwater causes soils to become wet and compact. On drying, the particles loosen and may shift from the original position down the slope.

(v) External forces such as moving vehicles and earth tremors trigger soil particles to move downwards.
