| Earth's Interior | ||
| #1 | Name the 3 MAIN layers. | crust, mantle, core |
| #2 | Oceanic crust is made if which type of rock? | basalt |
| #3 | Which layer is solid nickel? | inner core |
| #4 | What is the name for the upper part of the mantle? | asthenosphere |
| #5 | What creates Earth's magnetic field? | Currents in the outer core cause the inner core to spin a little faster than the rest of the planet. |
| Heat Transfer | ||
| #1 | Heat transfer through direct contact. | conduction |
| #2 | Heat transfer through empty space. | radiation |
| #3 | Heat transfer by the movement of heated fluid. | convection |
| #4 | Where does the mantle's heat come from? | The core. |
| #5 | What is cold? | The absence of heat |

| #3 | In the mid 1900s what did scientists use to map the ocean floor? | sonar |
| #4 | What was the original use of sonar? | Tracking enemy subs during WWII |
| #5 | What three types of evidence did Wegener use for his theory? | fossil, landfor, climatic |
| Theory of Plate Tectonics | ||
| #1 | What piece of evidence was Wegener missing from his continental drift theory? | What moved the continents |
| #2 | What causes the plates to move? | Convection currents in the mantle |
| #3 | What is a break in the Eart's crust called? | A fault. |
