How are the tides occuring on the seas/oceans????

Question

There are some people saying that the tides are occuring due

to moon's gravitational force on earth is it so.....i am need of further details abt it.

Answer 1

Yes tides occur because of the moon.

The moon pulls on the earth just like the earth pulls on the moon. But the effect of gravity is distance dependent, so the ocean on the moon side of the earth is pulled harder than the middle of the earth, and the ocean on the far side is pulled less. Consequently the ocean bulges both towards and away from the sun.

At the same time, the earth rotates - so the bulges are always lines up with the direction to the moon, but the earth;s surface moves under it. Consequently the point that starts at high tide will be in low tide 6 hours later and high tide again 6 hours after that and so on...

Answer 2

The Law of gravity states that all bodies exert a force on each other. This is effected by thee mass of an object and the distance from it. Regarding everyday objects on the earth, we measure it as their weight. They fall toward the earth inless there is another force acting on them.

Regarding the tides, the earth pulls on the moon and keeps it in orbit. The moon pulls on the earth an what is able to move is the large bodies of water, the oceans and seas, and up tidal rivers. When the moon earth and sun line up correctly, there are higher than normal tides because of the pull of the sun also. The high tide is 2 times a day as is the low tide. In the Chesapeake the wind is a great factor also as if we get a northerly wind it can blow the water out of the Bay and we do not get a high tide. Opposite that, if we get the right wind we get extremely high tides. Water level is also effected by tidal surge in storms. There is a seasonal variance also.
