Molecular attraction. That's what gravity is. Ever watch film of astronauts in space, and a small amount of water is let out from a vessel? The water floats in the cabin, and forms in to a sphere from its own molecular attraction. Space is a vacuum and any matter, such as planets and stars will also take on the sphere shape. However, the earth is not truly round. It's wider at the equator than from pole to pole. This is due to centrifugal force from spinning.

As the earth formed from the bits of junk around, it was molten and therefore went into the shape with the maximum surface tension (which keeps it together). That is a sphere. As it cooled, it adjusted to the slightly ovoid shape due to the effect of rotation.

It's not actually "round", it's more "spherical".
It's not a perfect sphere, either. It bulges some around the equator, but that's either due to centrigugal force, or just that it's so old it's developed a pot-belly.

It made itself round by gravitation. Strictly speaking it is an oblate spheroid.

While, of course, I wasn't there when the decision was made--it does help it spin and move through the solar system more evenly. (Cuts down on "wind resistance.")

So you don't fall off if you go too far.

Because SQUARE didn't rotate as well.
