Soil erosion - why do some fields lose their soil while others do not?
Earth Learning Idea (noreply@blogger.com)
Our ELI today is "Why does soil get washed away? - investigating why some farmers lose their soil through erosion whilst others do not". This ELI investigates the effect of vegetation cover in protecting soil from erosion in heavy rainfall. It provides the opportunity to explore some of the factors involved in limiting soil erosion. A teaching video accompanies this activity. The extension to the activity also gives some good ideas, including painting with different soil types. Related activitie
