Soil erosion - Wikipedia
WEBSoil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans ).

WEBApr 23, 2024 · Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. Splash erosion describes the impact of a falling raindrop, which can scatter tiny soil particles as far as 0.6 meters (two feet). Sheet erosion describes erosion caused by runoff.
What is Erosion? Effects of Soil Erosion and Land Degradation
WEBThe effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
Soil - Erosion, Conservation, Management | Britannica
WEBSoil erosion. Soil profiles are continually disrupted by the actions of flowing water, wind, or ice and by the force of gravity. These erosive processes remove soil particles from A horizons and expose subsurface horizons to weathering, resulting in the loss of humus, plant nutrients, and beneficial soil organisms.
