Earth & Space Science
The effects of surface condition, rain, wind, and slope, on soil erosion are explored through experimentation.
After completing this tutorial, you will be able to complete the following:
Each year, a significant amount of our country is washed away due to soil erosion, which may be one of today's most significant environmental problems. Soil erosion results in the loss of agricultural land, reduced crop yields, and other alterations to land structure that can be quite destructive.
In general, soil erosion is the loss or destruction of soil, usually due to transport by rain or wind, although other media exist. The surface slope of soil also impacts the rate of erosion due to gravity or dislocation by burrowing animals or other disturbances. Erosion is a natural process that can be healthy for an ecosystem, but that becomes a problem when human activity causes it to happen at a rate faster than it would in a natural environment. Poor land use practices, such as improperly managed construction activity, overgrazing, deforestation, improper crop rotation, and other agricultural practices lead to significant soil erosion. Natural or other ground cover, such as native vegetation, helps to conserve soil by protecting it from the elements. Other land use improvements and conservation efforts such as strict run-off and dust management practices on construction sites, limiting tillage when planting crops, constructing windbreaks, and planting ground cover, can also help prevent soil erosion.
