Problem 3
Is it possible for two igneous rocks to have the same mineral composition but be different rocks? Support your answer with an example.
Problem 4
Use your understanding of magmatic differentiation to explain how magmas of different composition can be generated in a cooling magma chamber.
Problem 5
Give two reasons sedimentary rocks are more likely to contain fossils than igneous rocks.
Problem 6
If you hiked to a mountain peak and found limestone at the top, what would that indicate about the likely geologic history of the rock there?
Problem 9
