Dynamic Earth
| Term | Definition |
|---|---|
| Geosphere | The rock portion of Earth, made up of different layers. |
| Athenosphere | Soft, slow-moving laver, beneath Earths crust. |
| Lithosphere | Earth's rigid outer/layer, made up of the crust and solid upper mantle that is broken into plates that move on to of the asthenosphere |
| Mantle | Layer beneath Earths crust that is mostly less solid then the crust. |
| Outer core | Liquid, metal layer surrounding Earths inner core |
| Inner core | Solid ,metal, center of the Earth with high pressure and temp |
| Crust | The thin hard outer layer of the Earth |
| Earth's layers from inner most layer to outer most layer. | Inner core, Outer core, mantle, crust. |
| The farther you go into the Earth the pressure ____ | Increases |
| Which layer is a solid metal ball made mostly of iron and nickel | inner core |
| Mostly composed of liquid nickel and iron | outer core |
| The movement of Earths plates is caused by convection currents found within which layer. | mantle |
| Which layer is made of the three different types of rock, igneous, metamorphic and sedimentary. | crust |
| Earth's layers from coldest to hottest | crust,mantle, outer core, inner core. |
| Why Earths inner core is solid? | high pressure. |
| The difference between outer core and inner core | the outer core is fluid and the inner core is solid. |
| true or false, The mantle is solid but can flow under pressure | true |
| true or false, the inner core is hallow | false |
| lithosphere | tectonic plates located in this sphere |
| continental crust | thickest of the crust, least dense of the crust, granite |
| oceanic crust | thinner then continental crust, more dense, basalt |
| convection currents | solid, most dense happen in the asthenosphere |
| mantle | 67% of Earths mass, magma. |
| mesosphere | middle phere |
| who came up with continental drift theory (CDT) | Alfred Wegener |
| continenta- contiental | -collision -2 continental crust collide, buckles up pushing the crust up. |
| continental-oceanic: | ocean crust crashes into cont. crust subduction: the denser crust (oceanic) slides under the dense crust (cont. crust) |
| oceanic-oceanic: | Denser ocean plate slides under the less dense ocean plate subduction: Trench under the water |
| CDT | The theory of all the contents being together. Evidence- rocks, fossils, glaciers, mountations, coast lines |
