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.
