Correct option is C
The correct answer is:(C) Meanders.
Explanation:
When a river enters the plains, it often twists and turns, forming large bends known as meanders.
These meanders occur due to the river's movement and the varying resistance of the soil and rock along its course.
As the river flows over flatter terrain, it loses speed, which allows it to curve and create winding, serpentine patterns.
Information Booster:
- Meanders are characteristic features of mature rivers, where the riverbed is wide and the flow is slower.
- The curves or bends in meanders can eventually form ox-bow lakes if the river cuts off a bend.
- Over time, meanders help in forming important landforms like flood plains and can alter the course of a river.
Additional Knowledge:
Ox-bow lake: An ox-bow lake is formed when a meander is cut off from the main channel of the river, creating a crescent-shaped lake.
Levees: Levees are raised embankments built along the riverbanks to prevent flooding.
Flood plains: Flood plains are flat areas of land adjacent to a river, prone to flooding.
