| What layer acts as both a solid and a liquid? | mantle |
| The inner core is made of | solid, hot, nickel and iron |
| What is responsible for the movement of the tectonic plates? | convection currents |
| where do most earthquakes and volcanos take place ? | At or near plate boundaries |
| What is the result of a transform boundary? | earthquake |
| what is the result of a convergent or divergent boundary? | volcano |
| What happens on a convergent boundary? | a subduction of the plates. |
| Wegener is best known for what theory? | Continental drift |
| What evidence do we have that Pangea existed? | Fossils, continents fit together like a puzzle, matching mountains, climate data |
| Where is most of the earth's material located? | the mantle |

| What is a large crack in the seafloor? | rift |
| when magma comes out of a rift it creates what? | crust |
| What happens to oceanic crust when it is pushed under continental crust? | it is subducted |
| if there is no ocean trench what happens to the land? | it pushes apart and mountains are formed |
| Where are most of the world's volcanoes located? | ring of fire |
| What is the active plate boundaries located on Asia and Europe ? | Alpide Belt |
| What is the divergent boundary running through the Atlantic? | Mid Atlantic Ridge |
| Where is it volcanically active yet far from a tectonic boundary? | hot spot |
