The correct answer is option 1: Tide. Tides refer to the rhythmic rise and fall of ocean water that occurs twice in a day. Tides are primarily caused by the gravitational forces exerted by the moon and the sun on Earth`s oceans. As the moon and sun orbit around the Earth, their gravitational pull creates bulges in the ocean water, resulting in high tides. The areas between the high tides experience low tides. These tidal patterns can vary depending on the phase of the moon and the tilt of the Earth. It is important to note that tides are different from ocean currents, which are defined as the continuous flow of seawater in a particular direction. Waves, on the other hand, are caused by wind blowing across the surface of the ocean, creating disturbances that propagate as energy through the water. The water cycle, also known as the hydrological cycle, is a different process that involves the movement of water between the Earth`s surface, atmosphere, and back.
