2. How can you use chocolate-chip ice cream to describe to a young child the concept of “magma” differentiation? In other words, can you make, starting with chocolate chip ice cream, a spectrum of flavors?
3. Explain two significant pathyways of magma differentiation for producing the spectrum of igneous rocks we find on Earth.
4. Explain how a chemically homogeneous system can provide two chemically identical (but very different looking) lavas during the process of eruption.
5. New Hampshire is the Granite State.
Explain what that information that provides about a geological feature New Hampshire used to have in its landscape long ago.
Explain also what finding granite here in New Hampshire means in terms of ancient tectonic setting of New England.

6. How does magma viscosity link to the morphology (shape) of the volcano that is formed?

7. How is the hazard predicted from a volcano linked with its tectonic setting?

8. Describe the six processes essential for forming most sedimentary rocks. How do these processes vary between clastic and chemical sedimentary rocks?
