Science Earth Layers
Earth'sLayers and Plates
| Term | Definition |
|---|---|
| Crust | the thin rocky surface that includes the continents and the ocean floor. |
| Mantle | the thickest layer. The rock material is solid, but it can flow like a liquid. |
| Outer core | made up of mostly iron and nickel. It is liquid |
| Inner core | made up of mostly iron and nickel. It is solid. |
| Heat and pressure | increase with as you go deeper beneath the surface. |
| What causes movement in the crust | The flowing mantle |
| The moving rock of the mantle | pushes against the crust causing the crust to break into plates. |
| There are three types of plate boundaries or faults | convergent, divergent, and transform. |
| Convergent Plates | collide in convergent movement (compression). |
| Convergent Plates Creates | folded mountains, volcanoes, ocean trenches |
| Divergent Plates | pull apart in divergent movement (tension). |
| Divergent Plates Creates | mid-ocean ridges in oceans. |
| Transform Plates | slide by each other in sliding movement (shear). |
| Lava | What magma is called when reaches the surface |
| Crust | This is the part of the Earth we live on |
| temperatures and pressures increase as | we move from the crust toward the inner core of the Earth. |
| The crust is very ____ compared to the other three layers | thin |
| Plates | Large continent-sized blocks are called |
| Transform plates grind against each other causing | earthquakes. |
| Ocean crust | Thin layer of crust found below the ocean. |
| Continental crust | Thick layer of crust that includes the continents. |
| Hydrosphere | is earth's water supply |
| Lithosphere | the land part of the earth |
| Atmosphere | the gases that surround the earth and help protect us from the sun |
