1. Farming: Farming practices such as plowing, tilling, and overgrazing can disturb the soil structure and vegetation cover, making it more susceptible to erosion. When the soil is left bare, it is more easily washed or blown away by wind and water.
2. Logging and mining: Clearing forests for logging and mining activities removes the protective vegetation cover that helps to hold the soil in place. Without this cover, the soil is more vulnerable to erosion from rainfall and wind.
3. Relief or physical shape of a particular area: The relief or physical shape of an area can also contribute to soil erosion. Steep slopes are more prone to erosion as gravity can cause soil to move downhill more easily. In addition, the presence of natural drainage patterns can lead to concentrated flow of water, which can further exacerbate erosion in certain areas.

Farming
- Tillage: Breaking up soil for planting can loosen soil particles, making them more susceptible to erosion by wind and water.
- Crop rotation: When different crops are grown in the same field year after year, it can lead to the depletion of organic matter and a reduction in soil stability.
- Overgrazing: Allowing too many livestock to graze in an area can compact soil, reduce vegetation cover, and expose soil to erosion.
Logging and Mining
- Deforestation: Removing trees from a landscape can significantly increase the risk of soil erosion. Tree roots help anchor soil in place, and their canopy intercepts rainfall and reduces runoff.
- Mining activities: Mining operations often involve the excavation of land, which can remove vegetation cover and create unstable slopes that are prone to erosion.
Relief or Physical Shape of Particular Area
- Slope angle: Areas with steep slopes are more susceptible to soil erosion because of the increased potential energy of water and wind.
- Aspect: The direction that a slope faces can influence the amount and intensity of rainfall it receives, which in turn affects the erosion potential.
- Soil type: Soils with a high percentage of sand and silt are more easily eroded than those with a higher clay content.
- Vegetation cover: The presence or absence of vegetation can significantly influence soil erosion. Vegetation roots help stabilize soil, and the canopy intercepts rainfall and reduces runoff.
- Climate: Areas with frequent heavy rainfall, strong winds, or extended dry periods are more likely to experience soil erosion.
