How do longshore currents move in relation to the shore?

Longshore currents are shaped by the angle at which waves break on the shore. As waves approach the coastline at an angle, they create a flow of water that runs parallel to the shoreline. This movement of water is the essence of longshore currents, which transport sediment and can affect coastal features over time.

Understanding this behavior is crucial for activities related to beach erosion, sediment deposition, and navigation. Recognizing that longshore currents flow parallel to the shore helps divers and beachgoers understand how ocean dynamics can affect their activities, as well as the impact on marine environments and coastal management practices.
