Question

1. researchers have noted that erosion occurs more slowly along the inner curves of river bends compared to the outer banks, regardless of which river they are studying.

which type of data would be most appropriate to collect in order to investigate this pattern?
the types of vegetation at a rivers inner bends compared to the outer bends
the types of land usage at a rivers inner bends compared to the outer bends
the soil content at a rivers inner bends compared to the outer bends
the speed of a rivers flow at inner bends compared to outer bends

Explanation:

Erosion is related to the force exerted by the river flow. The speed of the river's flow affects the erosive power. Faster - flowing water (usually on the outer bends) has more erosive force, while slower - flowing water (usually on the inner bends) has less erosive force. Vegetation, land usage, and soil content can also influence erosion, but the most direct factor related to the pattern of erosion (faster on outer bends and slower on inner bends) is the speed of the river's flow.

Answer:

the speed of a river’s flow at inner bends compared to outer bends
