Respuesta :

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:

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