Draw a sad face if the following activities help reduce soil erosion, sad face if it is not.

1. Planting a cover crop such as winter rye in vegetable gardens.
2. Removal of the vegetation covering the ground causes the soil, which is unprotected against wind and water, to erode.
3. Deforestation, which is logging or burning forests.
4. Putting stone walls prevent soil erosion. 5. Windbreaks can reduce wind velocities for a distance approximately 15 times the height of the tallest trees. As a result, there is a lower rate of soil loss across large crop areas.​
