Question

Quizplus · Accepted Answer

Longshore drift is the movement of sediment down the length of the beach in the direction of wave movement. It occurs when waves approach the shore at an angle, causing sediment to be pushed along the beach in a zigzag pattern. This movement is caused by the swash and backwash of waves and can result in the formation of sandbars, spits, and other beach features. Wave refraction refers to the bending of waves as they approach the shore and is not directly related to sediment movement. A breaker is a wave that has been disrupted by shallow water and is breaking on the shore. While it can contribute to sediment movement, it is not the main cause. Longshore current refers to the movement of water parallel to the shore and can also contribute to sediment movement, but it does not specifically refer to the movement of sediment itself.
