Question

1. diagram 1 below shows a river and diagram 2 shows a close up view of a portion of the same river. use the diagrams below to answer the question.

diagram 1
diagram 2
which of the following best explains how the bends, or curves, in a river are formed as seen in the diagram above?
meanders are created when sediments erode at point a and are deposited at point b.
meanders are created when sediments erode at point a and progress at point b.
meanders are created when sediments are deposited at point a and erode at point b.
meanders are created when sediments percolate at point a and remain in place at point b.
clear all

Explanation:

To determine how river bends (meanders) form, we analyze the processes at points A (outer bank) and B (inner bank) of a river bend. At the outer bank (A), the river flows faster, leading to erosion (sediments are removed). At the inner bank (B), the river slows down, causing deposition (sediments are laid down). Over time, erosion at A and deposition at B create the curved meanders. Among the options, the one stating "Meanders are created when sediments erode at Point A and deposit at Point B" aligns with this geomorphic process.

Answer:

The option (assuming the correct option is the third one from the left, based on the description) that states "Meanders are created when sediments erode at Point A and deposit at Point B" (exact option text may vary based on full visibility, but the key is erosion at A, deposition at B).
