Storm surge - wind-driven waves that flood low lying coastal areas. Coastal erosion - the loss of rock or sediment from a shoreline due to wave action, landslides, wind, and runoff. Rogue waves - huge wave produced by interference of small waves. Headlands - a peninsula on an irregularly shaped coastline that is more resistant to erosion than surrounding shoreline. Refract - direction of a wave changes direction when changing mediums. Divergence- the movement of two or more objects apart from one another. Convergence - the movement of two or more objects together. Sea cliff - a steep coastal bluff produced by wave erosion, landsliding, and in some cases ground water seepage. Bluff - a high steep bank or cliff along a lakeshore or river valley. Swash zone - an area on a shoreline where water runs up and recedes.
