In task 2 I only did part D

answer:

Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.
