Sample Multiple choice questions
____ 1. Which of the following statements best describes Johannes Kepler's model of the solar system?
|
a. |

|
b. |
The sun is the center of the solar system. The Earth is a planet orbiting the sun along an elliptical orbit just like all of the other planets. |
|
c. |
The Earth is stationary and at the center of the solar system. The sun, moon, and planets all orbit the Earth along perfectly circular Earth-centered orbits. |
|
d. |
