Multiple choice

What is the role of nebulae in the formation of planets?

  1. They provide the necessary material for planet formation

  2. They trigger the collapse of protoplanetary disks

  3. They regulate the temperature of protoplanetary disks

  4. They prevent the formation of planets
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nebulae play a role in the formation of planets by providing the necessary material for the process. The gas and dust in nebulae can collapse under its own gravity, forming protoplanetary disks, which are the precursors to planetary systems.
