formation of accretionary disk, formation of planetesimals, differentiation, formation of Moon

Explanation:

Materials from the nebula that were not absorbed by the sun composed a flat CD-like disk of dust and gas, held in orbit by the gravity of the sun. This is known as the formation of accretionary disk. The planets then start out microscopic in the accretionary disk, and after collisions, these particles start to form planetesimals. Obviously, differentiation is a consequence (which means it comes after). Lastly, assuming this question supports the theory that the earth had a collision with a much larger planet, billions of years ago, the material that was, essentially, shot into space, for lack of a better phrase. This caused the formation of our Moon.
