Answer Details
The tilting of tree trunks, poles, and piling of soil behind a wall are effects of soil creep. Soil creep is a slow and gradual movement of soil down a slope under the influence of gravity. It happens when soil particles are loosened by rain, freeze-thaw cycles, or other factors, and then they move slowly downhill due to gravity. The movement is often imperceptible, but it can cause visible effects like the tilting of tree trunks and poles, and the piling of soil behind a wall. Mud flow, rock slide, and landslide, on the other hand, are rapid movements of soil or rocks down a slope, and they usually happen as a result of a sudden disturbance like heavy rainfall or earthquake.
