• Overgrazing - reduces the small plants likegrass and weeds which help in holding thesoil.
• Overcultivation - the act or practice ofcultivating land to an excessive degree in thegrowing of crops so that soil quality isdegraded and productivity is reduced
• Effects of Soil Erosion on Landforms - Soil erosion can destroy large masses of land. It can also transform amountain into a hill or plateau. Excessive deforestation, mining, and conversion ofthe mountain to residential or commercial land could trigger erosion that can bedestructive to the environment. These activities damage the slopes of mountainsand other high landforms that cause the formation of landscapes such as sanddunes.
• Effect of soil erosion

  • Soil unable to hold or absorb water
  • Soil becomes dry, coarse, and unfit for vegetation
• Too much soil erosion
