Answer :

The periodic rise and fall of water levels in the oceans are called tides. The rise in water level causes high tides. It occurs due the gravitational pull of the moon as well as the centrifugal force due to earth’s rotation. High tides occur twice a day. To explain this statement further we take the example of a place A. When place A faces the moon, the water levels rise forming high tide due to the gravitational pull of the moon. The rotation of the earth takes around 24 hours which implies that place A would be in the exact opposite direction after 12 hours since it faced the moon. Place A then experiences another high tide, this time owing to the centrifugal forces of the earth arising out of rotation. Thus, place A has high tide twice in a 24-hour period.
