The process of accretion in planetary formation is the:
A) slow condensation by gravity of gas atoms into large, dense gas clouds that are the preplanetary masses.
B) slow acquisition from deep space by the giant planets of their complement of moons by gravitational capture.
C) slow accumulation of solid particles by gravity and collision into larger, solid objects.
D) relatively rapid gravitational collapse (in less than 10⁶ years) of gas clouds to form planets.

Question

Quizplus · Accepted Answer

The process of accretion in planetary formation involves the slow accumulation of solid particles by gravity and collision into larger, solid objects. This process ultimately leads to the formation of planets. The other options, such as the slow condensation of gas atoms or rapid gravitational collapse, do not accurately describe the process of planetary accretion.
