Plates - Alice C.
| Question | Answer |
|---|---|
| What type of plate boundary has plates that slide against each other and cause shearing? | Transform Boundary |
| What subducts into the mantle when a convergent boundary is continental to oceanic? | Oceanic crust |
| When two plates are moving away from each other, what type of boundary is this? | Divergent Boundary |
| What type of plate movement causes earthquakes? | Transform and sometimes convergent |
| The mid-atlantic ridge is an example of what type of boundary? | Divergent boundary |
| When two plates collide, what type of boundary is this? | Convergent boundary |
| What does a divergent boundary create? | A rift valley |
| Where do most volcanoes and earthquakes occur? | Along plate boundaries. |
| Who developed the Theory of Continental Drift? | Alfred Wegener |
| What does magma become when it reaches earth's surface? | Lava |
| What happens in a continental to continental crust collision? | Mountains and sometimes volcanoes are formed |
| The Himalayan Mountains are an example of what? | A convergent boundary; continental to continental crust |
| What stress does a divergent boundary cause? | tension (pulling apart) |
| What happens in a continental to oceanic crust collision? | The oceanic crust subducts; makes trench and/or volcanoes |
| What happens in an oceanic to oceanic crust collision? | They either both subduct, or the denser one subducts; forms trench and/or volcanic arch |
| How do convection currents work? | Magma gets hotter near the center of the earth. Hot magma is less dense, so it rises up. If it's not pushed to the surface, it goes to the side and submeerges aga |
| Name the 3 types of plate boundaries | Convergent, Divergent, Transform (not necessarily in this order) |
| Does seafloor spreading make the earth bigger? | No |
| Can a divergent boundary create new crust? | Yes |
| Crust is destroyed or recycled at what type of plate boundary? | Convergent |
| Which layer of the earth is the thinnest? | Crust |
| Which layer of the earth is the hottest? | Core |
| The chemical layers of the earth are... | crust, mantle, core |
| The physical layers of the earth are... | asthenosphere, lithosphere, mesosphere, inner core, outer core |
| What is the core primarily made of? | Nickel and iron |
