The movement of the droplets of sea water going high and low as well as forward and backward is called 'Sea waves'. The normal waves are caused due to the wind blowing over the sea surface. High waves are formed by stormy winds (whirlwinds) or by cyclones. These are high and long. These sea waves cause heavy destruction when they reach the seacoasts.
