Question

Quizplus · Accepted Answer

Accretion is the growth of an object by the accumulation of matter. It is a key process in the formation of planets and other astronomical bodies. Accretion is the process of an object growing larger by the accumulation of matter, usually through gravity. This is how planets and other bodies in our solar system were formed - particles in the solar nebula clumped together and gradually grew larger through accretion.
