Coastal Geography Concepts Assessment

The video discusses erosion and its impact on beaches, focusing on the concept of longshore drift. It explains how waves shape coastlines by moving sediments, leading to the formation of features like Cape Cod, barrier islands, and sandbars. The video also covers human interventions like jetties and groins, which attempt to control sediment movement. Safety tips for beachgoers, such as avoiding undertows, are provided.
