1. erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location. Erosion is distinct from weathering which involves no movement.
2. Rainfall and Runoff, Soil Erodibility, Slope Gradient and Length, Cropping and Vegetation
3. reduced ability of the soil to store water and nutrients,
exposure of subsoil, which often has poor physical and chemical properties.
higher rates of runoff, shedding water and nutrients otherwise used for crop growth.
loss of newly planted crops.
deposits of silt in low-lying areas
