GREAT 13-minute segment about Mars from "60 Minutes"

In case you missed it, this is a GREAT segment that includes several important Earth Science concepts - Earth's magnetic field, plate tectonics, law of superposition, erosion, meteorites, etc. Consider showing it as you teach about the rock cycle. Here are some possible questions to guide a discussion after showing it.

1. Is there a "rock cycle" on Mars?
2. How is it different from the rock cycle on Earth? What processes are missing?
3. Is there molten rock on Mars?
4. Are there metamorphic rocks on Mars?
5. What drives the rock cycle on Earth?
