10 which graph best represents the relationship

10. Which graph best represents the relationship between a planet’s average distance from
the Sun and the time the planet takes to revolve around the Sun?
11. Which object orbits Earth in both the Earth centered (geocentric) and Sun-centered
(heliocentric) models of our solar system?
(1) the Moon (3) the Sun (2) Venus (4) Polaris
12. The Sun’s position in space is best described as the approximate center of
13. The diagram to the right represents two
planets in our solar system drawn to
A 14. Compared to Earth’s solar system, the universe is inferred to be
15. Terrestrial planets move more rapidly in their orbits than the Jovian planets because
terrestrial planets are
(1) rotating on a tilted axis (3) more dense
(2) more massive (4) closer to the Sun
16. Which event is a direct result of Earth’s revolution?

Base your answers to questions 17 through 19 on the information, data table, and diagram
below and on your knowledge of Earth science.
and planet D . Some of
the information gathered about these three new planets is shown in the table below. The
period of revolution for planet C has been deliberately left blank.
The diagram below compares a part of our solar system to the Upsilon Andromedae
planetary system. Planet distances from their respective star and the relative size of each
planet are drawn to scale. [The scale for planet distances is not the same scale used for
planet size.]
17. Planet D’s diameter is 10 times greater than Earth’s diameter. What planet in our
solar system has a diameter closest in size to the diameter of planet D
18. As planet B travels in its orbit, describe the change in orbital velocity of planet B as the
distance between Upsilon Andromedae and planet
19. If our solar system had a planet located at the same distance from the Sun as planet
is from Upsilon Andromedae , what would be its approximate period of revolution?
C

Base your answers to questions 20 through 22 on the data table below, which shows one
cycle of equinoxes and solstices for the northern hemispheres of several planets in the
solar system and the tilt of each planet’s axis. Data for the planets are based on Earth’s
time system.
