Oceanic movements refer to the movement of water in the ocean, which is largely driven by the gravitational pull of the moon and the sun. Tides are one of the most common forms of oceanic movements, which are caused by the gravitational pull of the moon and the sun on the Earth's oceans. Tides cause the water level to rise and fall twice a day, creating a cycle of high and low tides. Other oceanic movements include ocean currents, which are large-scale movements of water that are driven by wind, temperature, and salinity. These currents can affect the climate of coastal regions and can also be used to transport goods and people across the ocean.
