The removal and transport of soil by agents such as flowing water or wind.

Water flowing over the surface carries away topsoil. This is soil erosion, and it reduces the land’s fertility. Rainwater can also dissolve nutrients and carry them down through the soil: this is leaching, a different process from the physical removal of soil.

The removal and transport of soil by agents such as wind and flowing water.

Remember that soil erosion is an impact of food insecurity as well as a cause of future shortages.

Explain a chain of effects: name the activity, show how it changes vegetation or the ground surface, then link this to a physical process such as soil erosion.

The removal of soil by processes such as wind and flowing water.

The wearing away and removal of soil by agents such as flowing water.

With less protective vegetation, soil becomes more exposed to rain and flowing water, increasing soil erosion. Soil washed into streams can also reduce water quality.
