Aristotle's model is shown. Who developed this model to support his theory of the solar system?

• Aristarchus

• Corpernicus

• Galileo

• Ptolemy

How did Aristotle explain the way that objects in the universe moved?

• circles on small spheres inside large spheres with the Earth at the center

• in elliptical orbits on one giant sphere with the sun at the center

• in circles on one giant sphere with the Earth at the center

• in elliptical orbits on spheres with the Earth at the center

How does Aristarchus' view of the solar system compare to Aristotle?

• They are both geocentric.

• They are both heliocentric.

• Aristarchus' view is geocentric, and Aristotle's is heliocentric.

• Aristarchus' view is heliocentric, and Aristotle is geocentric.

Early astronomers couldn't see parallax, but how did Aristotle explain this problem?

• Earth is not moving.

• The stars are very far away.

• Parallax is undetectable to the eye.

• Viewers need to move to detect parallax.

How did Ptolemy's model of the solar system compare with Aristotle's model?

• Both showed celestial objects with elliptical orbits.

• Both showed celestial objects with circular paths.

• Both were based on parallax.

• Both were heliocentric.

According to Kepler, how do objects move in the solar system?

• elliptical orbits around the sun

• circular orbits around the sun

• elliptical orbits around the Earth

• circular orbits around the Earth

The picture shows what Galileo saw when he looked at Jupiter. What does the diagram show?

• Planets have elliptical orbits.

• All celestial objects orbited Earth.

• All celestial objects orbited the sun.

• Planets other than Earth had objects orbiting them.

The image shows what Galileo saw when he looked at Venus. What did Galileo conclude?

• Venus is always lit.

• Venus travels around the sun.

• Venus is farther from the sun than Earth is.

• Venus has moons, and the moons have phases.

Which statement is NOT part of Copernicus' theory of the solar system?

• The sun is stationary.

• Planets travel in elliptical orbits.

• Earth rotates on its axis, causing day and night.

• Earth revolves around the sun, causing seasons.
