________ form when waves that approach the beach at an angle and produce a net current direction that is parallel to the shore, resulting in beach drift.

Question

Quizplus · Accepted Answer

Longshore currents form when waves approach the beach at an angle (due to refraction) and the resulting net current direction becomes parallel to the shoreline, leading to the transport of sediment and the formation of beach drift. Rip currents are strong, narrow currents that flow away from the beach and are dangerous for swimmers. Eddies are circular currents that can occur within larger ocean currents.
