Why is backswamp formation associated with natural levees?
Answer and explanation
Correct answer: Levees block drainage in the lower area behind them
A natural levee is a raised river-bank ridge formed when floodwater loses energy and deposits sediment near the channel. The land immediately behind it is lower and receives less direct drainage, so floodwater and groundwater can remain there, producing a marshy backswamp. Thus option A is correct; the other choices describe unrelated marine, glacial, or aeolian processes.
