Because the closer to the center of mass you are, the mass in this case being the planet, the stronger the gravity. Knowing that, you can imagine how there are gravity gradients surrounding the earth, and it is natural for energy to return to its lowest state, in the case of mass, its lowest state of energy without changing state woud be to locate its self in a position with the lowest potential.
The location with the lowest potential is the location closest to the center of mass, and given enough time, and the planets have had plenty, the potential will be equally distributed amoung all matter, which results in a circle...
Same as a water droplet in zero gravity.

Gravity pulls all of the planet's mass evenly towards a central point.

They are not really round, but more oval in shape: they look like weeble wobbles ... but they don't fall down.

round core, then it grows (oddly, its growing round), then pop.
maybe cause of gravity.
