When things erode, they wear away due to some force acting on them. Just look at any coastline, and you will notice how the constant pounding force from wind and waves causes erosion of the rocky structures, leaving behind all kinds of interesting cliffs, caves and structures. Soil is not immune to erosion, and like rocks along a coastline, soil can erode due to the effects of forces, such as water, wind and farming practices. In this lesson, we will learn about soil erosion and the factors that cause it.
