For Essay Section You will need to answer ONE of these sets of questions. Know them all to be fully prepared. Full sentences are required, though tabular presentations are fine.

Terra Forming Mars Know arguments in favor and against terra forming Mars. What is required to make the surface livable for plants? For Humans? Why will it never be entirely safe on the surface?

The Geology of Venus. What is the age of Venus' surface and how do we know this? Is there plate tectonics occurring or what? Is there a convective mantle? How are Earth and Venus' geology similar and how are they different?

Titan's pre-biotic, organic soup. Describe Titan's atmosphere and surface (chemistry, pressure, etc)? How do we know the atmosphere and surface conditions? In what ways is Titan like the pre-biotic Earth. Why is this important?

Our Solar System. How did the Solar System form? What clues are present in the characteristics of the planets and minor planets (asteroids, comets, etc)? How does this theory explain the density and composition of the planets as a function of distance from the Sun?
