Earth Science 113/114
1. Name and describe the layers of the Earth. How do these layers
affect earthquake waves? How do earthquake waves help us to
know what earth’s interior is like?
2. Explain what convection currents are. Where in earth’s interior do these occur (be specific)?
What effect do convection currents in the mantle have on Earth’s surface?
3. Describe Wegener’s theory of continental drift in detail (i.e. – what are plates, what was the
supercontinent called, what evidence supported his theory, etc).
4. Describe each plate boundary – transform, convergent, divergent. How do the plates move at
each of these, what happens, and what features form (i.e. – trench, volcanic island chain,
volcano on continent, mountain range, earthquake, rift valley, subduction, mid ocean ridge).
5. Explain how the Hawaiian islands formed and the evidence that helps us understand how they
formed (review lab 2.09).
6. Describe a composite cone volcano in detail. How do these form? What are the different parts
of one?
7. Describe the gases that are emitting from a volcanic eruption. What affect do they have on the
atmosphere and planet?
8. Describe P and S waves. How are they similar? How are they different?
9. How do we locate the epicenter of an earthquake
10. There is gold found in South America (where the Inca’s lived) where there are volcanic
mountains along the coast. Explain, how does plate tectonics explain this (which types of plates
are involved here and what type of boundary is there?).
11. Explain sea floor spreading – where does this happen and what happens? What evidence do
scientists have that this happens?
12. How did each of these form – Japan, Mariana trench, Alps, Andes
