6. Gravity formed the planets
-True
-False

It’s true because gravity is what pulled the dust and minerals and formed them into plants and dwarf planets.

True

Explanation:

When the dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. At the center, gravity pulled more and more material in. Some of them grew big enough for their gravity to shape them into spheres, becoming planets, dwarf planets and large moons.
