Erosion is when wind, water, or other natural agent wears away at rock and takes it to a new place. This take millions of years to happen. As the wind or water etches away at the rock, the pieces of soil or rock that come off get carried to someplace new. Erosion can cause damage when homes are built on cliffs. Erosion can tear apart the cliff and damage the homes. Erosion creates some of the beautiful landforms we see today. Erosion can make many landforms. It can make canyons, when a river wears away rock as it flows. Erosion can also make wild and wacky shapes. Arches are formed when wind or water erodes the rock to for an arch shape. The Grand Canyon was formed by water from the Colorado River that eroded the rock. This took thousands of years to happen!
