River action is a significant geomorphological process that shapes the landscape over time through erosion, transportation, and deposition of materials. This process can lead to the formation of distinct landforms in river valleys.

Landform 1: V-shaped Valley

Formation Process: The V-shaped valley is formed primarily through vertical erosion. As the river flows downwards, it cuts into the bedrock. The sides of the valley erode due to weathering, which causes debris to fall into the river, enhancing the process further.

Diagram: A simple diagram can illustrate how a river cuts through a landscape, showing the ramp-like sides of the valley.

Landform 2: Meander

Formation Process: A meander is another landform created by river action. As the river flows, it erodes the outer banks and deposits sediments on the inner banks. Over time, this lateral erosion leads to the development of a winding, curving path in the river.
