Question

Quizplus · Accepted Answer

Soil creep is a slow mass movement of soil down a slope due to the force of gravity. The primary factor that contributes to soil creep is moisture, which acts as a lubricant, reducing the friction between soil particles and allowing them to move downslope. In arid regions, where there is a lack of water, the soil is dry and compact, which reduces the potential for soil particles to move downslope. Therefore, the lack of water removes the primary lubricant, making soil creep unimportant in such regions.
