Soil ErosionWhat causes it?

How can we prevent it?

Page 2: Soil Erosion

In which layer does soil erosion

occur?

Page 3: Soil Erosion

Why do these cows need to stop eating?

Overgrazing

Page 4: Soil Erosion

What in this picture might cause erosion?

Construction- removes vegetation and loosens

soil

Page 5: Soil Erosion

What is happening to cause erosion?

Deforestation- removal of trees for

building or profit

Page 6: Soil Erosion

How could this cause soil erosion?

Plowing and other farming techniques leave soil loose and vulnerable to wind, water, and

gravity. Continuing to plant the same kind of crop in the same place can be deplete the nutrients in the soil.

Causes Preventions

All are caused by overuse or removing vegetation
