You might think that, because the length of the tide cycle is determined by the Earth's rotation, the tide cycle should be 24 hours long. The reason it's longer is that, during a 24-hour period ...

As the tides move the mass distribution of the oceans around the solid parts of the Earth, its rotational inertia varies slightly with a period of 12 hours. There are also seasonal variations due ...

That's how quickly Earth rotates on its axis, from West to East. And that rotation is largely responsible for the distribution of every desert, forest, and swamp on the planet. So, let's do a ...
