Tides are created because the Earth and the moon are attracted to each other, just like magnets are attracted to each other. The moon tries to pull at anything on the Earth to bring it closer. But, the Earth is able to hold onto everything except the water. Since the water is always moving, the Earth cannot hold onto it, and the moon is able to pull at it. Each day, there are two high tides and two low tides. The ocean is constantly moving from high tide to low tide, and then back to high tide. There is about 12 hours and 25 minutes between the two high tides.
Tides are the periodic rise and falling of large bodies of water. Winds and currents move the surface water causing waves. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side). Ocean levels fluctuate daily as the sun, moon and earth interact. As the moon travels around the earth and as they, together, travel around the sun, the combined gravitational forces cause the world's oceans to rise and fall. Since the earth is rotating while this is happening, two tides occur each day.

Changing of the tide is caused by the shifting of the
ocean floors. Also the global warming is having a dramatic
effect on our oceans causing tidal waves of massive destruction,

the tide changes , due to the magnetfeild, from the earths rotation, day from night

the pull of the moon on the earth, its a matter of how close to the moon we are at a given time. its all a matter of how much gravity is being manipulated by the movements of the moon upon the earth.

Moon's gravitational pull + Earth's rotation = Tidal ebb and flow.

the moon's gravity as it goes through it's rotation around the earth, getting closer then farther away.
