This Is How Do Ocean Waves Form And Why They Are Continuous?

Normal ocean waves result from the frictional drag of wind on the surface of the water. The waves you observe at a given beach may originate thousands of kilometres away,whereas tsunami waves are caused by displacement of the crust caused by an earthquake. Waves have a crest and a trough, the distance between crests being known as the wavelength. Waves travel in groups called a wave train. Waves are not all moving at the same speed. When one wave catches up to another you can end up with an even higher wave. This is called constructive interference.  Ocean waves can travel hundreds of kilometres before they reach the land. The distance of water over which the wind has blown is called the fetch. A long fetch will result in big waves and big waves carry with them a tremendous amount of energy. Storms create destructive waves thus a lot of erosion takes place during storms,Even on calm days it is possible to get big waves as these ones have been generated in a storm somewhere else some ti
