Question
Which two statements about the geocentric model are true? Select the TWO correct responses. (1 point)
• It shows the Sun at the center of the solar system.
• It explains why Mars appears to move backward for a few months approximately every two years.
• It shows the orbits of the planets as circular.
• It shows the Earth at the center of the solar system.
It is true that the Earth orbits the Sun. What is the shape of the Earth's orbit as it goes around the Sun? (1 point)
• an ellipse that is almost circular
• a circle
• an elongated ellipse
• a spiral
What is the relationship between a planet's orbital velocity and its distance from the sun based on Kepler's Law? (1 point)
• The greater the distance, the slower the orbital velocity.
• Distance has no effect on orbital velocity.
• As distance is cut in half, orbital velocity decreases.
• The greater the distance, the greater the orbital velocity.

• Most planets have elliptical orbits.
• The distance of the planet from the sun varies during the orbital period.
• The distance between Earth and the sun remains constant during the orbital period.
