Question

describe how the surface of the water changed as the wave travelled past

Answer 1

Wave transport $energy$ not the water.As the wave travel past the water surface water remain more or less at the same position.It only oscillates up and down at its position.Like any other wave , a water wave appears to move up and down in a pattern.So, the wave passes through the water but $water \ particles$ end up in the same place they began.
