Rivers shape the landscape over time through erosion, transportation, and deposition processes. As a river flows, it erodes the land by carrying away sediment and wearing down rocks. This erosion can create valleys, canyons, and other landforms. The river then transports the eroded material downstream, where it can be deposited in new locations, such as river deltas or floodplains. Over time, these processes can dramatically change the landscape, forming diverse features and shaping the environment around the river.
