Step-by-step explanation:
Erosion is caused by the debilitation of the soil, and one of the most common reasons for erosion is clearing forests, also called deforestation, plants and their roots help keep the soil in their place and use the water that runs through the soil helping avoiding erosion, Plowing fields are fields that take advantage of the elevation in the soil and plant in different levels of elevation, helping with this to prevent erosion in the soil.
