Water Moves Soil
After a rainstorm, have you ever noticed muddy water running down the sidewalk? Or seen dirt washed away from a hillside? That is erosion!
Erosion is when water, wind, or ice moves soil and rock from one place to another. Water is the most powerful erosion force on Earth. Over thousands of years, water carved the Grand Canyon, which is over a mile deep!
Erosion changes the shape of the land. Rivers cut valleys, waves shape coastlines, and rain washes soil down hills. Today you are going to see erosion happen right in front of you!
