Ocean movements refer to the various motions of the ocean, such as tides, currents, and waves. Tides are the regular rise and fall of the sea level caused by the gravitational pull of the moon and sun. They occur twice a day and can be seen in most coastal areas. Currents are the continuous movement of water in a certain direction, usually caused by wind or differences in temperature and salinity. Waves are the result of wind blowing over the surface of the ocean, causing the water to move in a circular motion. All of these ocean movements have a significant impact on the environment and the lives of people living near the coast.
