Why does the tide come in and go out?
|
As the Moon and the Earth swing round each other, ocean water is thrown to the side of the Earth away from the Moon. At the same time, the moon's gravity attracts water to the side facing the Moon, resulting in two periods of high tide every 24 hours. | | The Moon is relatively close to the Earth! |
