4. What do all outer planets have in common?
- A. They are solid, dense, and rocky (magenta)
- B. They have liquid surfaces and gaseous inner layers (yellow)
- C. They have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings (sky blue)

5. Why are the outer planets called gas giants?
- A. because they are mostly composed of oxygen and/or nitrogen (red)
- B. because they are mostly composed of helium and/or hydrogen (golden yellow)
- C. because of the very strong winds that happen on their surface (magenta)

6. What do all inner planets have in common?

14. How does the time it takes for a planet to orbit the Sun change as you move through the solar system?
- A. Planets closest to the Sun take the longest time to orbit (yellow green)
- B. Planets farthest from the Sun take the longest time to orbit (yellow orange)

Answer :

Final answer:

The questions about the Solar System cover key concepts including the Sun's central position, planetary characteristics, and orbital mechanics. The distinctions between inner and outer planets are emphasized, along with the formation timeline and measurement units. Key terms such as gas giants and terrestrial planets help clarify the differences among solar system objects.


Explanation:

Questions and Answers on the Solar System

1. The celestial object at the center of the Solar System is the Sun.

2. The Earth takes approximately 24 hours to complete one rotation on its axis.

3. The Sun's gravity holds all the planets in orbit around it.

4. All outer planets, or gas giants, are similar because they are mostly composed of hydrogen and helium.

5. The outer planets are called gas giants because they primarily consist of gases and have small rocky cores.

6. All inner planets, or terrestrial planets, are characterized by being rocky and having metal cores.

7. Terrestrial planets have higher temperatures than Jovian planets because they are closer to the Sun.

8. Uranus's axis is so tilted that it appears to rotate on its side.

9. The band of celestial objects between Mars and Jupiter is called the asteroid belt.

10. Scientists have calculated that the Solar System formed approximately 4.6 billion years ago.

11. Objects that are NOT part of our solar system include stars that are NOT the Sun.

12. Distances within our Solar System are measured in astronomical units.

13. The object in our solar system with the greatest mass is the Sun.

14. As you move through the solar system, the time it takes for a planet to orbit the Sun generally increases because planets farther from the Sun take longer to orbit.
