Tides are the rise and fall of ocean water. They are the combined effects of the gravitational forces exerted by the sun and moon on the rotation of the Earth.
The tides of the ocean rise and fall due to the gravitational pull of the moon and sun on the Earth. This gravitational force creates bulges of water on opposite sides of the Earth, causing the water level to rise and fall in a cyclic pattern as the Earth rotates.
