How does the flowing water of a river shape the land?

The flowing water of a river has great power to carve and shape the landscape. Many landforms, like the Grand Canyon in the U.S. state of Arizona, were sculpted by rivers over time. This process is called weathering or erosion. The energy of flowing river water comes from the force of gravity, which pulls the water downward.
