Question

The image below shows a point bar and a cutbank of a meander. What happens to sediments at these locations?

Answer 1

Answer:

D Sediments are eroded from a cutbank and deposited on a point bar

Explanation:

A cutbank and point bar are common features of a meandering stream. This feature usually occurs when a river reaches a flat plain.

Meanders occur along the length of the river as it continues to move.

• At the outer concave part where  the cut bank lies, there is rapid erosion of sediments.
• In the inner convex part, the sediments are deposited to for a point bar.
• Most of the sediments here are usually fine to medium grained sediments.
• Sediments are brought from outside the bend where velocity is very great.
• The inside of the bend has low velocity and the sediments are deposited.
