Great question! The tide that you see at the shore is a forced oscillation in a basin. What does that mean? Its just like sloshing the water around in your bathtub. You will notice that the water in the tub moves up and down, but doesn't actually 'go' anywhere else. Same thing with ocean tides. They make the ocean move up and down, but the water is not really moving large distances. Now, the two principal things making the tide are the sun and moon. Primarily the moon. Combining the gravity from these with the rotation of the earth gives us two principal periods, diurnal (24hr) and the semi-diurnal (12hr).

As to the highs and lows, it is a pretty complicated situation. You can imagine if your bathtub had edges that followed the coastline of the Atlantic or Pacific oceans, that the 'sloshing' would not be very even! There are even places in the ocean, called amphidromes, where there is virtually no tide. Other location, like the North Sea, have very large tides. Primarily, when it is high tide at one location, it is low tide on the other side of the basin, but that is a gross simplification.

Hope that helps!

Tides are created by the pull of gravity from the moon, so when it is high tide in one place, it is low tide somewhere else.
To describe it simply, the water in the oceans sort of follows the moon around

Take a metallic tray, about 2 cm deep, and fill it with water. Tilt it quite and attempt to get the water operating from one end to the different. you receives moist even though it really is going to illustrate how tides "economic corporation up" as they frame of mind a shallow shore.

THE OTHER SIDE OF THE OCEAN SUCH AS LOW TIDE ON THE EAST COAST USA ATLANTIC OCEAN IT'S HIGH TIDE ON THE OTHER SIDE EUROPE AND AFRICA.
