Describe how soil erosion can limit the use of land as a resource, and explain how this problem can be overcome.

Answer:

Soil erosion removes the nutrient-rich topsoil that plants need, making land less fertile and limiting its usefulness for growing crops. It can also carry sediment into streams and other waterways. The problem can be reduced by keeping soil covered with plants or cover crops, planting windbreaks, and using practices such as contour plowing or terracing on slopes.
