Because when it condensed from the stellar nebula that formed it, the gravity of all the particles pulled evenly throughout. So the result was spherical. Basically the earth pulls everything toward the center, and all the matter wants to get closer to the center so it tries to be equidistant from that point. The result is a sphere.

It is the way earth formed. Before earth and the other planets, there was dust and rocks moving around space. As they came closer together, they started to pull together, forming gravity. Since the "pull" is evenly in all directions, and spinning usually starts along the way (two things I have no idea how they work; the gravity part and the spinning part), it forms a ball shape as everything moves inward essentially the same time. So round we get...
PS The moon came later. Something big and round hit earth, smashing BOTH into pieces again. The pulling and spinning started all over again, making the Earth, and the moon.

Gravity pulls the Earth into a sphere. Anything bigger then say, Mt. Everest will collapse under its own weight. If the earth were square, the corners of the square would fall under their own weight and the earth would become a sphere, as it is now.

Because.... The void of space is a weightless vacuum, and most any liquid mass, such as a planet forming, will assume a spherical shape in that environment. Plus God made it that way, why question it?

Yes a good one. I was waiting for someone to ask this. I didn't want anyone to fall over the edge when walking the dog or that kind of thing that isn't covered by your standard insurance, get me?

If the Earth were squake, with all that spinning, circular wind, the water, wouldn't it get eroded down anyways?? It is not very earodynamic if it were square. hehehee

I don't think square is a natural occurence in nature. it spins around and the corners get knocked off. circles are more likely to be seen in animals, rocks, etc.

It was supposed to be square apparently. But God decided to cut corners.
