Ocean wave is an example of a surface wave. They travel along the surface of the Earth, on oceans, like the name suggests. They travel a bit slower than other waves, and slowly dissipates when it reaches shallow water level. The most common ocean waves are generated by the friction of the wind and the ocean surface. Other energies that pass through water can also generate ocean waves, that causes it to have a circular motion.
Like surface waves, earthquakes and volcanic eruptions (that generate p and s-waves) can cause an ocean wave called tsunami. They roll the shore and can reach lands, which can cause destruction.
