- Describe the process of nuclear fission. How does it work and when is it used? What is meant by a chain reaction, and how do you control it?
- Compare and contrast two planets in our Solar System with Earth. What are the signature features of those planets and how do they compare to Earth?
- List the three types of rocks. Select an example of rock from one of these rock types and describe the processes that make that rock. What might happen to that rock to make it change into a rock in different place in the rock cycle, and what kind of rock would it become under those circumstances?
- List the four types of weather fronts. Select one of these fronts and describe the conditions necessary for that front to occur. What kind of air masses are involved and how do they interact? What are the characteristics that you might observe during that kind of front?
