Question

Where is erosion concentrated along a meandering stream?: a) on the inner banks of the meander loops along point bar; b) at the center of a stream where water velocity is the lowest; c) on the outer banks of the meander loops; d) on the depositional bank of the meander loops; e) on the straight channel segments that connect the meander loops

Answer 1

c) on the outer banks of the meander loops

Step-by-step explanation:

The meandering streams form in places that have low elevation and are flat, covered with softer sediments. The stream starts as mostly straight, but as time passes it erodes one of the banks, while depositing on the opposite bank, become very curvy, snake-like in shape, thus a meandering stream. In the meandering streams, the water has the most velocity at the outer banks. This results in greater erosion of the outer banks, and this part constantly moves outwards. In the same time, the water has the least velocity at the inner bank, resulting in deposition of the material that it has been carrying with it, so this part constantly grows inwards.
