**  Know the difference between a scientific theory and hypothesis.

**  What is Earth Science and Earth System Science?  Why do we need to study Earth Science?

**  Know that the Universe > Galaxies > Solar System > Planets > Earth >Moons.

**  What is the Big Bang Theory?  What is the basis of this theory? What is critical mass?  What are some likely possibilities about the fate of the Universe?

**  What is the Nebular Hypothesis?  How does this hypothesis help us understand or explain various observation about our planet, it’s atmosphere, ocean, magenosphere, and layered Earth.

Chapter 24/22:

**   Know the names and order of all planets in the Solar system.
