The video explores the dynamic interaction between land and sea along the northwest coast of America, focusing on erosion and deposition processes. Erosion shapes coastlines by forming cliffs, caves, arches, and stacks, while deposition creates beaches and spits. The video explains how wave energy, local geology, and wind conditions influence these processes, resulting in diverse coastal landscapes.
