Which of the following statements best describes how the planets of the solar system formed?

  • They are condensed rings of matter thrown off by the young Sun.
  • They are the remains of an exploded star once paired with the Sun.
  • The Sun captured them from smaller, older nearby stars.
  • They formed from a nebular cloud of dust and gas.
  • They formed from a nebular cloud of dust and gas.

How do plants most commonly break large rocks into smaller pieces?

  • Plant leaves insulate surrounding rocks from extreme temperature.
  • Plant roots grow into cracks in rocks.

Our solar system is thought to have formed from a nebula of dust and gas. Most of this nebula condensed to form the Sun.

What is primarily responsible for causing these materials to condense?


  • Electrical attraction between charged dust particles
  • Gravitational pull of nebula materials on each other
  • Heat released by nuclear fusion at the center of the nebula
  • Chemical reactions between hydrogen and other nebula gases
  • Gravitational pull of nebula materials on each other
