What is the path followed by a sand grain from a succession of waves impinging obliquely onto a beach?
A) A sawtooth path, driven obliquely up the beach face with the swash then straight down the beach face with the backwash.
B) Perpendicular to the wave front, obliquely up the beach on the swash, then reflected out at an opposite but equal angle with the backwash.
C) A path parallel to the beach, but well offshore as sand is only moved by longshore currents not by breaking waves.
D) A straight path, right at the shoreface, pushed along parallel to the beach by the breaking wave.
