Which is the largest cause of soil erosion quizlet?
Running water is the leading cause of erosion because it can easily take soil with it as the water flows downhill or moves across the land.
What are the 3 major causes of soil erosion?
Different Soil Erosion Causes
- Sheet erosion by water;
- Wind erosion;
- Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
- Gully erosion – when water runoff removes soil along drainage lines.
- Ephemeral erosion that occurs in natural depressions.

What causes the highest soil depletion and erosion worldwide?
Water and wind erosion are the two primary causes of land degradation; combined, they are responsible for about 84% of the global extent of degraded land, making excessive erosion one of the most significant environmental problems worldwide.
What is soil erosion and what are its two major harmful environmental effects?
Erosion of topsoil has two major harmful effects. One is loss of soil fertility through depletion of plant nutrients in topsoil. The other is water pollution in surface waters where eroded topsoil ends up as sediment, which can kill fish and shellfish and clog irrigation ditches, boat channels, reservoirs, and lakes.
What is soil erosion and its causes?
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

Where does soil erosion occur most?
Soil erosion usually happens in overly disturbed soil systems especially with unfavorable weather conditions. In tropical areas, rainfall and water flow are the main reasons causing soil erosion, whereas on the Loess Plateau of China, water erosion is a great problem.
