24.5 Essay Questions

1) Compare and contrast terrestrial and Jovian planets.

2) Using the nebular theory, explain the formation of our solar system from the formation of the

solar nebula through the present day.

3) Conspiracy theorists argue that the United States never went to the Moon and that the lunar

landings were staged. What pieces of evidence could be used to prove the United States did land

on the Moon?

4) Compare the surface of the Earth to that of the Moon. Why doesn’t the Earth’s land retain the

same scarring from meteorite impact as the Moon? Why doesn’t the Earth’s ocean retain the same

scarring from meteorite impact?

5) Explain the impact hypothesis for the formation of the Moon. Be sure to discuss why the

Moon contains a higher ratio of silicate minerals (i.e. plagioclase) than the host body.

6) Compare and contrast the core of Mercury (40% of volume) to that of Earth (~10% of

volume). If Mercury is smaller, why is that core bigger than that of Earth’s?

7) Compare and contrast Earth’s Moon and the planet Mercury.

8) Mauna Loa, a shield volcano in Hawaii, is approximately 10 km in height. Olympus Mons is a

shield volcano on Mars that is approximately 27 km in height. Compare the formation of both of

these volcanoes. How is it that Olympus Mons could grow so much taller than Mauna Loa?

9) Over the last several decades, there have been many individuals who have proposed

colonizing the Moon and using it for mining substances such as Hydrogen and Helium-3. Is this

a feasible venture? Why or why not? Provide a detailed explanation.

10) How do the interior layers of a Jovian planet compare to the interior layers of a terrestrial

planet? Be specific.

11) In 2006, the International Astronomical Union developed a formal definition for what

constitutes a planet. What are the three parts of this definition? How does Pluto meet or not meet

these three criteria?
