A baymouth bar is a depositional feature as a result of longshore drift. These bars usually consist of accumulated gravel and sand carried by the current of longshore drift and deposited at a less turbulent part of the current. Material is pushed up onto beaches at an angle when the swash brings it onto the coastline at a 45 degree angle.

A headland is eroded and the sand is deposited in an offshore basin B. 179. Tectonic shifts and sea level changes cause the long-term rise and fall of sea level relative to land. As wave enters shallower water than wave base, its develops friction with sea floor. The Sun: It drives all external processes on Earth.
