Mod H Unit 2 Lesson 1 - Quiz

Which statement disagrees with Laplace’s hypothesis of the sun’s formation?

• The sun gradually cooled over time.

• The sun began to shrink after it formed.

• The sun began to rotate faster after it formed.

• The sun’s mass moved toward the outer edge of it.

Immanuel Kant proposed the nebular hypothesis for the origin of the solar system as a single cloud of material rotating in a single direction. Which object in our solar system is the most similar to the nebula in composition?

• sun

• Mars

• Earth

• Mercury

A student rubs an inflated balloon with wool. The student moves the balloon over bits of paper, and the balloon attracts it. Which statement best describes how the balloon models the early formation of planets in the solar system?

• The balloon and the planets are both constructed from bits of matter that they collect.

• The balloon circles over the bits of paper, just as the planets circle around each other.

• The balloon and the planets both display orbital motion around a larger body of mass.

• The balloon attracts bits of paper, just as the planets attract matter that is around them.

Where in the solar system are most gases found, other than the sun?

• the inner planets: Mercury, Venus, Earth, and Mars

• the outer planets: Jupiter, Saturn, Uranus, and Neptune

• the Kuiper belt: disc of dwarf planets beyond the orbit of Neptune

• the asteroid belt: disc of asteroids between the orbits of Mars and Jupiter

Which statement summarizes how the formation of the solar system was similar to the differentiation of Earth into layers?

• In both processes, the most massive materials moved to the center.

• In both processes, the most massive materials moved to the outside.

• In both processes, the most massive materials were evenly distributed.

• In both processes, the most massive materials formed the middle layer.

Which of these is most likely the next stage after the one shown in the illustration?

• new star is formed

• the cloud of dust and gas begins to spin

• planets develop with individual orbits

• the disk flattens with the star at the center

Which stages involve the collision and clumping of matter in the nebula? Select all that apply.

• stage 1

• stage 2

• stage 3

• stage 4

• stage 5

Why are there two different types of planets in the solar system?

• The amount of material available to form planets was greater in the outer reaches of the protoplanetary disk.

• Rocky material could not collect and form planets beyond the asteroid belt.

• The nebular cloud from which the solar system formed had very little gas.

• The sun’s heat allowed only rocky planets to form in the inner portion of the solar system.
