There are three types of ocean movements waves, tides, and currents. They are
Waves: Waves are actually the energy, not the water as such, which moves across the ocean surface. Water particles only travel in a small circle as a wave passes. Wind provides energy to the waves. Wind causes waves to travel in the ocean and the energy is released on shorelines.
Tides: The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide.
Currents: Ocean currents are like river flow in oceans. They represent a regular volume of water in a definite path and direction.
