Answer to Question 1

Answer: Particles suspended in the water move through circular orbits of decreasing diameter at deeper depths. The circular wave motion of water imparts a small amount of forward movement of the water. The motion beneath the passing wave decreases downward, so a particle of water moves farther when it moves up and forward than when it moves down and backward. Therefore water actually does move slowly in the direction of wave movement.
