The earth is round because it is NOT a solid thing but a conglomerate made of pieces that are self attracting because of gravity. The sphere is the lowest potential energy state of what is essentially a fluid. The sphere provides the least distance between atoms that are attracting the other atoms surrounding them, equally in all directions.
Positive: 62.5 %

It's round from its own gravity. Gravity's force wants to pull everything towards its center. If a mountain got too high for example, the gravity would collapse it. Since this happens at every point on the surface in all orientations the result is a sphere.
Positive: 50 %
