Many people think, the tides exist because the moon attracts the water on earth, but this isn't fully true, because that would mean that the tides change tides every 24 hours, but they chance every 12 hours. For explaining the second tide change you have to think about the moon and earth, like they are 1, turning around its axis. http://upload.wikimedia.org/wikipedia/commons/5/59/Orbit3.gif Tides Tides are the rising and falling of [|Earth] 's [|ocean] surface caused by the [|tidal forces] of the [|Moon] and the [|Sun] acting on the oceans. Tidal phenomena can occur in any object that is subjected to a gravitational field that varies in time and space, such as the Earth's land masses. The Bay of Fundy, shown on the east coast of North America Much people think the tides are existing because the moon attracts the water, this is not fully true, because this would mean we would have a tide-chance every 24 hours, we have one every 12 hours. To explain why its every 12 hours, you got to think about the moon and earth like they are 1, turning around its axis. Just like here; http://upload.wikimedia.org/wikipedia/commons/5/59/Orbit3.gif And because this middle point doesn’t lay in the middle of the earth, there exists a groundswell, turning to the moon. The other groundswell is caused by the turning of the earth, just like the day/night changing. A old mythe In the sea the water comes up on the land, and than it ebs away again. The scientists understand now why: The below of the earth is a fish, called Chewa, and on the back of Chewa lies a big stone. On that big stone stands a cow with seventy thousand horns and forty thousand legs. On his horns lies the earth, the earth is fastened on his horns, his nose lies in the sea, and every day he breaths once. When he breaths in, all the water flows away. But in the end, only God knows.
