Explain how longshore currents form. Explain how rip tide currents form
What will be an ideal response?
Answer: Where refracting waves approach the shoreline at an angle, the water is forced to move parallel to the coast and away from where the waves converge onto the shore. Each arriving wave contributes more water into the longshore current, and this water cannot pile up along the shore because gravity is pulling the excess water back out to sea. As a result, part of the current flows offshore as a rip current.
