Sheet erosion occurs when a thin layer of topsoil is removed uniformly across a wide area, typically caused by the surface runoff from heavy rainfall.

Soil erosion is removal of top soil by agency of water (water erosion) and wind (wind erosion). Soil erosion is of two types- natural and anthropogenic. Natural or geological erosion is extremely slow removal of top soil due to rain water or wind. Anthropogenic soil erosion is caused by removal of plant cover through over grazing, litter collection, tree felling, leaving the soil unprotected during agricultural operations.

Soil erosion is the removal of top soil by the agency of water (water erosion) and wind (wind erosion). Soil erosion is of two types, natural and anthropogenic. 

Heavy downpours provide high kinetic energy that dislodges soil particles more effectively than gentle, steady rain. This rapid runoff carries away the topsoil before it can be absorbed.

Soil erosion is the removal of top soil, top soil has all the nutrients necessary for plant growth. Eroded soil is low on fertility

Soil erosion is the process of washing and wearing away of the top fertile soil due to the physical pressure and force of water, wind or other farming activities like tilling, ploughing etc.
The soil can be prevented from getting eroded by planting and raising more trees as the roots of the trees hold the soil tightly and prevents it from getting washed away.
Deforestation means cutting down of trees and more we cut down the trees more the soil will be left loose and easily washed away and get eroded.
Excessive use of fertilizers can leave the soil degraded, loose, dry and barren and more vulnerable and easier to get eroded.
Overgrazing by animals can leave the soil loose, dry and barren totally exposed to get washed away and get eroded completely.

Siltation is the accumulation of sediments in water bodies. These sediments are primarily the result of upstream soil erosion being washed into the drainage system.

Soil erosion is the process by which soil and surface materials are detached and transported by agents like water, leading to the sedimentation of water bodies.

Erosion is defined as the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.

Soil erosion involves the removal of the top layer of soil which adversely affects the fertility of the soil. Heavy rainfall leads to splashing of soil. However, the majority of the soil splashed is not immediately lost from the field. Most of the splashed soil particles don't leave the field, they clog surface pores, which in turn reduces water infiltration, increases water runoff, and increases soil erosion.
