| #2 | List the layers of the Earth from hottest to coolest. | inner core, outer core, mantle, crust |
| #3 | Which layer of the Earth vibrates in place because of the pressure? | inner core |
| #4 | What is the only liquid layer of the Earth? | outer core |
| #5 | What type of rock is the oceanic crust made of? | basalt |
| B | ||
| #1 | What is the thickest layer of the Earth? | mantle |
| #2 | Which layer of the crust is more dense? | oceanic |
| #3 | Why is the inner core solid? | All of the other layers put so much pressure on this layer, so it makes it a solid. |
| #4 | What type of rock is the continental crust made of? | granite |
| #5 | How is the heat from deep in Earth's interior transferred to the crust? | convection currents in the mantle |
| C | ||
| #1 | Which layer is the most dense? | inner core |
| #2 | What are the two types of crust? | oceanic and continental |
| #3 | What is the name of the movement in the mantle? | convection currents |
| #4 | How are the inner core and outer core alike? | They are both made of iron and nickel. |

| #2 | What is the solid layer of the Earth that is capable of flow? | mantle |
| #3 | What two layers make up the lithosphere? | bottom of crust and top of mantle |
| #4 | How are the inner core and outer core different? | Inner core is solid; outer core is liquid. (Inner is also hotter.) |
| #5 | What three things are the greatest in the inner core? | pressure, density, and temperature |
