WebThe slope of a coast is critical to determining how water-level changes will affect it. Steeply sloping coasts experience small shifts in their coastlines as the water level changes; however, because wave action along steep coasts is concentrated within a narrow zone, small water-level increases can result in significant erosion of bluffs or dunes. WebThe key factors which affect coastlines are: The rock type/geology (see map below). Hard rock types are less likely to erode. The fetch of the wave and the strength of the wind. Powerful...

WebIntense storms and higher seas create more winds, waves, and floods, leading to increased coastal erosion. Hurricanes can wash away sandy barrier islands, leaving coastlines and islands unprotected from storm surge. Waves and winds can carry away beach sand little by little, shrinking scenic beaches. WebAs wind blows over the surface of the water, it disturbs the water, producing the familiar shape of a wave. You can see this shape in Figure 10.14. The highest part of a wave is called the wave crest. The lowest part is called the wave trough. The vertical distance from the highest part of a wave to the lowest is called the wave height.
