Identify the correct description of the process depicted in the image:

• Gravity pulls the gas and dust in and causes it to rotate

• Chemical differentiation separates the heavy elements from the light

• A massive explosion, creating heavy elements

• Planetesimals continue to collide with debris and other planetesimals to form protoplanets

• Rotation creates a massive disk of material called a solar nebula

What is the nebular hypothesis?

Answer explanation

The nebular hypothesis is a theory that explains how solar systems, including planets and other celestial bodies, form from a rotating, flattened cloud of gas and dust called a "solar nebula."

How do planetesimals form?

• By the accumulation of dust and gas in solar nebula

• By the collision of two planets
• By the explosion of a star
• By the gravitational pull of a black hole
