How are tides useful for us?

First answer is also correct but might be my ans is little bit different than first. 1 point Definition : Tide : The rhythmic rise and fall of ocean water twice in a day is called a tide. 2.point Now little bit information on tides : It is high tide when water covers much of the shore by rising to it's highest level. It is low tide when water falls to it's lowest level and recedes from the shore. 3. Point : There are two types of tides 1st. Spring tides : the full moon and the new moon day's and when the sun, the moon and the earth are in the same line and the tides are highest. They are spring tides. 2nd. Neap tides : when the moon is in it's first and last quarter, the ocean waters get drawn in diagonally opposite direction's by the gravitational pull of sun and moon resulting in low tides. These are neap tides. 4th. Point : How are the tides caused? Answer : The strong gravitational pull exerted by the sun and the moon on the earth's surface causes the tides. And the importance of the tides you can take from 1st number answer . Bye

Tides are useful because : 1. Tides help to navigate.' 2. During high tide , the saline sea water is stored in low lying coastal areas. This saline sea water is spread out in the fields and is used to make common salt. 3. During high tide the fished come to the coast. This makes it really easy for the fishermen to catch the fish without having to go into the open water. 4. The energy of tides is used to generate electricity. Tidal power stations have been set up in UK , Japan , France and Canada. 5. Tides help to clear the sediments deposited by rivers on their beds and thus prevents siltation of harbours. ( Siltation is the process by which water becomes dirty as a result of fine mineral particles in the water.)
