Erosion is the wearing away of land by wind, water, and ice. There are three main types of erosion: wind erosion, water erosion, and ice erosion. Water erosion can carve out canyons and widen rivers, while ice erosion acts like sandpaper on wood. Erosion can threaten structures like houses and driveways if not prevented, as it can cause trees to fall and land to wash away. Simple steps like planting vegetation and building rock walls can help limit erosion.

Make a rock wall at the
edge or side of streams,
rivers, or even in your

erosion!

20. Erosion is a Natural
Process!
Do your part to limit the
