According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size?

Question

Quizplus · Accepted Answer

As the solar nebula shrank in size, it got hotter due to gravitational contraction, its rate of rotation increased due to conservation of angular momentum, and it flattened into a disk due to the combination of rotation and magnetic forces. This allowed for the formation of the planets through accretion. Option A is incorrect because it incorrectly states that the solar nebula gained energy rather than getting hotter. Option C is incorrect because it incorrectly implies that the solar nebula became more massive as it shrank, which is not the case. Option D is incorrect because it describes processes that occurred after the solar nebula had already formed the planets, rather than the changes that occurred during the process of forming the planets.
