Q:

Soil erosion can be prevented by

A) Removal of vegetation B) Overgrazing
C) Afforestation D) Increasing bird population

Answer:   C) Afforestation



Explanation:

The four most common soil erosion prevention methods are vegetation, geotextiles, mulch, and retaining walls.

By planting grass in areas of concentrated water flow, farmers can prevent much of the soil erosion that results from runoff, as the grass stabilizes the soil while still providing an outlet for drainage.

Preventing soil erosion is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-effects of the forest fire.
