| Hey so there are some graphs on the quiz that I don’t know how to turn into cards. It’s just basic maths, so as long as you graduated the 4th grade you should be fine. | Oh ok cool thanks man. |

| The thin and solid outmost layer of the Earth. | Crust |
| Located between the inner core and the mantle. | Outer Core |
| Strong lower part of the mantle. | Mesosphere |
| The thick layer of rock between the earth's crust and core. | Mantle |
| The solid innermost part of the earth, composed mostly of iron and nickel under extremely high pressure and temperature. | Inner core |
| The solid, plastic layer of the mantle made up of mantle rock that flows very slowly, which allows tectonic plates to move on top of it. | Asthenosphere |
| The solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle. | Lithosphere |

| Provide examples of Metamorphic rocks | phyllite, schist, gneiss, quartzite and marble |
| Provide examples of Sedimentary rocks | breccia, conglomerate, sandstone, siltstone, and shale |
| How are Igneous rocks made? | Cooled and crystallized magma |
| How are Metamorphic rocks made? | Rocks subjected to heat and pressure |
| How are Sedimentary rocks made? | Formed from pre-existing rocks undergoing weathering and pressure |
| How does a volcano form? | Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. |
| Where does a volcano form? | Most volcanos form at the boundaries between tectonic plates. Some however occur under “hot spots” |
| Name all types of fault boundary’s. | Normal, Reverse, and Strike-Slip Faults |
| Label the layers of the earth. | Inner core, outer core, mantle, and crust |
| Label the layers of the earth. (Sphere terminology) | Lithosphere, Asthenosphere, Mesosphere |
| Define convection currents. | Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns that move the lithosphere. |
| Name some tools scientist used to study volcanos. | portable monitoring station, Global Positioning System, digital monitors, Thermal imaging |
