Getting to Know: Erosion by Water
... Flowing water acts as an agent of erosion because it contains small pieces of rock and sediment. These particles can wear down and erode the rocks in a riverbed. If a river contains a lot of fast-moving water, it can rapidly erode Earth’s surface. In addition to canyons, many landforms result from t ...
