Ripple marks.

Ripple marks develop in soft beds of sand in shallow water. The two directional movements (back and forth) of waves create symmetric ripple marks. Asymmetric ripple marks occur when waves move in one direction. Graded beds form when there is rapid deposition with water that has varying sizes of sediment, making the sediment coarse at the bottom ...Ripple marks were measured and macrofauna and sediments were sampled near to and far from subtidal rocky reefs at two sites. Ripples were significantly wider and taller close to than far from reefs.Explanation: Undulation is defined as the to and fro wavelike motion in a fluid or elastic medium.
