Wave processes KI 5: Coastal Landforms

Factors making big waves- 1) Fetch – the length of open sea over which the wind has blown 2) Wind strength and how long the wind has been blowing strongly etc.

Types of Waves 1) Constructive – would tend to build up beach deposits by deposition

Types of Waves 1) Destructive – would tend to erode away beaches leaving cliffs exposed to erosion – occur in stormy weather
