Question

Which is built to prevent beach erosion? A.delta B.groin C.levee D.sandbar

Answer 1

in my opinion i will choose groin because groin interrupts the water flow in the beach or it limits the water flow. And without this there will be erosion everywhere.

have you seen a line of rocks going to the ocean? that's a groin.
