1. A diagram of the solar system shows the sun in the middle. Why does every other object orbit around the sun?(1 point)
A. The sun is the most massive object in the solar system.
2. A student looks at an animated model of the planets orbiting the sun. What should the model show to demonstrate why planets do not end up going into the sun?(1 point)
B. The planets move too fast to go into the sun.
3. Why could rockets blast off from the moon more easily than from Earth?(1 point)
D. The pull of gravity on the moon is one-sixth of that on Earth.
4. A student makes a chart that shows the similarities between a moon and asteroid. Which similarity should be included?(1 point)
A. They both orbit larger objects.
5. The planets of the solar system are classified into two main groups. What are the names of those two groups?(1 point)
B. One group is called the inner or terrestrial planets, and the other group is called the outer or giant gas planets.
6. The planet Uranus is between Saturn and Neptune. What is a reasonable estimate for the distance, in AU, from Uranus to the sun?
A. 20
7. How does the greenhouse effect enable life on Earth?(1 point)
C. It allows the atmosphere to retain heat.
8. Use this paragraph: A scale model of the solar system shows a dot placed at the center to represent the sun. Mercury is approximately 60,000,000 km from the sun and is placed on the model at a distance of 10 cm from the dot. Likewise, the Earth is approximately 150,000,000 km from the sun.
At which distance from the dot should Earth be placed in the model? (1 point)
B. 25 cm
9. Use this paragraph: In a scale model of the solar system, the distance between Jupiter and Saturn is 17.2 cm, while the distance between Saturn and Uranus is 38.8 cm. The astronomical unit distance between Jupiter and Saturn is 4.3 AU.
What is the astronomical unit distance between Jupiter and Uranus?
D. 14 AU
10. What is an advantage of using a model to study the solar system?(1 point)
B. You can study all of the planets together in one model.
11. A student creates a scale model of the planets in the solar system. How should the size of Jupiter compare to Mercury if the scale is accurate?(1 point)
A. It will be thirty times the size.
12. Which planet in the solar system has the most gravity?
A. Jupiter
13. How do scientists describe the arrangement of the early solar system?
B. a rotating disk of space rocks and gases
14. Why it is difficult for scientists to locate the oldest rocks on Earth?(1 point)
A. Rocks are constantly eroded by weather.
15. Which scientific evidence best supports the theory that Earthβs history includes mass extinctions?(1 point)
C. the presence and then absence of fossils in rock layers
