Question: Which choice describes how an erosional floodplain develops? Need Assignment Help? View Available Hint(s)for Part A A stream approaches a graded condition, starts eroding, and starts meandering. As the stream meanders, it widens the valley by continuously eroding the banks on both sides and downcuts the bedrock below the meander. This widened and downcut valley is an erosional floodplain. A stream approaches an increase in gradient, starts eroding, and starts meandering. As the stream meanders, it widens the valley by continuously eroding the banks on both sides and downcuts the bedrock below the meander. This widened and downcut valley is an erosional floodplain. A stream approaches an extreme decrease in gradient, starts depositing its suspended load, and starts meandering. As the stream meanders, it widens the valley by continuously eroding the banks on both sides. This widened valley is an erosional floodplain. A stream approaches a graded condition, stops eroding, and starts meandering. As the stream meanders, it widens the valley by continuously eroding the banks on both sides. This widened valley is an erosional floodplain. A stream approaches a graded condition, starts depositing the sediment in its suspended load, and starts meandering. As the stream meanders, it widens the valley by continuously eroding the banks on both sides and downcuts the bedrock below the meander. This widened and downcut valley is an erosional floodplain.
