Define soil erosion.

Soil erosion is defined as the removal of the top layer of soil due to natural forces such as wind or water. This process is significant because the topsoil is typically the most fertile layer, rich in nutrients and organic matter necessary for plant growth. Erosion can occur gradually over time or rapidly due to specific events, such as heavy rainfall or strong winds.

When soil is eroded, it leads not only to the loss of soil fertility but also impacts water quality and ecosystem health, as the displaced soil can carry pollutants into nearby water bodies. Recognizing the causes and effects of soil erosion is crucial in land management practices to preserve soil health, promote sustainable agriculture, and protect the environment.
