Question

What role did gravity play in the formation of the planets?

A.
The gravitational forces inside small asteroids pushed outward, causing the asteroids to swell to the size of planets.
B.
Planet-sized bodies passing by the solar system were pulled in by Earth's gravity and fell into orbit around the Sun.
C.
Gravitational forces brought together several moon-sized bodies, called planetesimals, to form larger bodies that became planets.
D.
The gravity of the Sun was too weak to hold it together, and large pieces of the Sun broke off to form the planets.

C. Gravitational forces brought together several moon-sized bodies, called planetesimals, to form larger bodies that became planets.

This answer accurately describes the role of gravity in the process of planetary formation. In the early solar system, gravity played a crucial role in attracting and merging smaller bodies known as planetesimals, eventually leading to the formation of larger planetary bodies.
