Which statement best illustrates the role that gravity played in the formation of the solar system?

Question

• Gravity caused the nebula to cool enough for planets to form.
• Gravity allowed the nebula to expand and move outward.
• Gravity removed excess gas and dust from the cores of the planets.
• Gravity pulled particles of dust and gas together to form planets.

Answer 1

The statement that best illustrates the role that gravity played in the formation of the solar system is:

• Gravity pulled particles of dust and gas together to form planets.

This statement accurately reflects the fundamental process through which gravity facilitated the aggregation of matter in the early solar system, leading to the formation of planets.
