Question

which statement accurately describes planetesimals? they were created during the big bang. they contain 98% of matter in the solar system. they formed from ice and rocks. they are the origins of planets.

Explanation:

Planetesimals are small celestial bodies formed in the early solar system from the accumulation of dust, ice, and rocks. They are the building blocks that merge to form planets. The Big Bang created basic elements, not planetesimals; the Sun contains ~98% of solar system matter, not planetesimals; while some planetesimals have ice/rocks, the most defining trait is being planetary origins.

Answer:

D. They are the origins of planets.
