What land shapes can be formed by running water?

Answer 1

Water itself has little erosive power except on friable materials such as sand, earth, and gravel. Once there materials are in transport, they may be used as abrasive processes to shape even the hardest and resistant rocks.

So valleys and gorges are formed, and unusual shapes such as waterfalls and U-shaped valleys.

Eventually, the gravels and silts are deposited as the water speed slows, though even at zero water velocity, the suspended fine silts will disperse in the sea or a lake and may take weeks to settle.

Answer 2

Running water can create various land shapes, including valleys, canyons, river deltas, alluvial plains, and meanders. Erosion and deposition processes, such as abrasion and sedimentation, play a key role in shaping the land through the movement of water over time.
