Tides are caused by the gravity of the Moon. As the Earth spins round, the water in the oceans is 'pulled' towards the Moon slightly, making a bulge. There is a corresponding bulge on the other side of the Earth.

Wherever the bulges are positioned it is high tide. In between the water is shallower and so it is low tide.

High tides occur every 25 hours, because at the same time that the Earth is spinning on its axis, the Moon is travelling around the Earth once every 27% days.
