Question

The map below shows a meandering stream. Points A, B, C and D represent locations along the stream bottom.

At which location is the greatest amount of sediment most likely being deposited?
1)A
2)B
3)C
4)D

Answer 1

C

Step-by-step explanation:

At point C, maximum sediment will be deposited because of several reasons. At first, A, B, and D are directly along the flow path therefore erosion rate would be high on these points. However, C is not located on the path of stream rather it is on the lower end. Therefore, water will erode material from distant (front end) end, and deposit sediment on lower end. Secondly, C is located downstream and therefore have high chance of load deposit compared to the upstream points.

Answer 2

3)C

Step-by-step explanation:

Point C on this meandering stream will have the largest amount of sediment most likely deposited.

Along a meandering stream, there are cut banks and point bars.

• The point bar here is region C and the cutbank is A.
• The mid stream is B.
• Along a point bar, there is deposition because the part of the stream slows down here .
• At a cutbank, the velocity is high as the stream moves very fast.
• A cut bank and point bar typifies every meandering stream on a flat plain.
• As the river collides with the adjacent area due to its velocity, it removes materials rapidly to form a steep cut bank.
• The point bar is where those materials are deposited.
