The diagram below represents the interiors of three planets in our solar system. Which inference best describes the interiors of the planets in our solar system?

• Both terrestrial and Jovian planets have layered interiors, with density increasing toward the center.

• Both terrestrial and Jovian planets have layered interiors, with density decreasing toward the center.

• Only terrestrial planets have layered interiors, with density decreasing toward the center.

• Only Jovian planets have layered interiors, with density increasing toward the center.

Which statement best explains why Earth and the other planets of our solar system became layered as they were being formed?

• Materials that cooled slowly stayed at the surface of each planet.

• Materials that cooled quickly stayed at the surface of each planet.

• Gravity caused more-dense material to move toward the center of each planet.

• Gravity caused less-dense material to move toward the center of each planet.

• Jupiter

• Mars

• Neptune

The terrestrial planets differ from the Jovian planets because the terrestrial planets are

• less dense and larger

• less dense and smaller

• more dense and larger

• more dense and smaller

Base your answer to the question on the diagram below. The diagram represents the inferred stages in the formation of our solar system. Stage 1 shows a contracting gas cloud. The remaining stages show the gas cloud flattening into a spinning disk as planets formed around our Sun.

Which force was mostly responsible for the contraction of the gas cloud?

• friction

• magnetism

• gravity

• inertia

Why do the planets in our solar system have a layered internal structure?

• Each planet is composed of materials of different densities.

• The Sun exerts a gravitational force on the planets.

• Cosmic dust settled in layers on the planets’ surfaces.

• All planets cooled rapidly after they formed.
