← GeographyWhich outcome results from overbank deposition forming levees?
A)Elevated stream banks and floodplains✓
B)Subsidence of delta channel sediments
C)Increased river water infiltration rates
D)Decreased dissolved carbon dioxide levels
💡 Explanation
The formation of natural levees causes elevated stream banks, because sequential overbank deposition results in sediment buildup alongside the channel through the mechanism of aggradation; therefore, the floodplains become more elevated than the river itself, rather than subsiding or changing infiltration rates.
