Question

the nebular theory is the most widely accepted theory about the formation of the solar system.
a a gigantic cloud of gas and dust collapsed.
b. the force of gravity pulled the particles in the nebula towards one another, forming a rotating disk.
c. as the nebular particles moved closer together, intense pressure blew them apart.
d. the suns great mass formed from the matter that was at the center of the disk.
which statement(s) support the nebular theory best?
o a only
o d only
o a, b, and c
o a, b, and d

Explanation:

The nebular theory states that the solar system formed from a collapsing nebula. Option A describes the initial collapse of the nebula. Option B explains how gravity pulled particles together to form a rotating disk. Option D is about the formation of the Sun from the mass at the center of the disk. Option C is incorrect as pressure does not blow the particles apart in the context of the nebular theory's accepted mechanisms.

Answer:

A. A gigantic cloud of gas and dust collapsed.
B. The force of gravity pulled the particles in the nebula towards one another, forming a rotating disk.
D. The sun's great mass formed from the matter that was at the center of the disk.
