Erosion and Deposition

Trees are important for many reasons. The roots of trees can hold soil in place, which helps to reduce soil erosion. Erosion can threaten environments by removing essential nutrients as soil is displaced. Please view The Forest & The Soil Cycle from eMediaVA℠to learn how trees in the forest can reduce soil erosion.

After watching the video, consider the following questions:

• How do large trees and vegetation in the forest environment protect the soil from erosion?
• What different sized sediments compose soil?
• How does sediment size affect growing conditions?
