Coastal Erosion Theories

Coastal erosion theories explain how coastlines gradually wear away due to natural processes. These include wave action, where the constant impact of waves weakens shoreline materials; weathering, which breaks down rocks through temperature changes and chemical reactions; and currents that transport sediments away, reshaping the coast. Human activities, like construction and dredging, can accelerate erosion. Theories emphasize the balance between these forces and the natural geology of the coastline, helping us understand why some shores erode faster than others and guiding efforts to protect coastal areas.
