What factors affect the processes operating along a stretch of coastline?

The rock type/geology

The angle of the slope

Weather conditions

The amount of vegetation

The amount of human interference

The key factors which affect coastlines are:

The rock type/geology The fetch of the wave and the strength of the wind. The angle of the slope - steep slopes erode more violently and frequently. Weather conditions - freezing temperatures and heavy rain increase weathering and the rate of erosion.
