| Question | Answer |
|---|---|
| Layer of Earth that is hot, solid, and liquid | Mantle |
| Oldest fossils are in this layer | Bottom |
| Rocks are based on texture and | Minerals |
| As depth into Earth increases, the temperature | increases |
| Type of rock formed when existing rocks are changed by heat and pressure | Metamorphic rocks |
| Type of rock formed by compaction and cementation | Sedimentary rocks |
| These currents in the mantle cause the movement of tectonics | Convection |
| Responsible for the formation of the mid-ocean ridge | Seafloor spreading |
| This determines crystal size of igneous rocks | Cooling time |
| Eruption of these results in formation of igneous rocks | Volcanoes |
| Sea-floor spreading causes this to form | Crust |
| Reason for earthquakes to be found along Ring of Fire is due to crustal plate | Boundaries |
| Help determine relative age of sedimentary rocks | Fossils |
| Metamorphic rocks are classified on whether or not they have these | Bands |
| Layer of Earth that is very dense,hot, and metallic | Core |
| Resulted in same type of fossil found on continents on both sides of the Atlantic Ocean | Plate tectonics |
| The crust is _____ with softer material in the mantle below it | Solid |
| Type of rock formed by cooling and hardening | Igneous rock |
