What are tides and how are they caused?

Answer :

The rhythmic rise and fall of ocean water twice in a day are called tide. The strong gravitational pull exerted by the sun and the moon on the earth’s surface cause the tides. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon.  The rise and fall of water due to tides is used to generate electricity in some places.
