Earth's Layers
| Part of Earth | Description |
|---|---|
| Asthenosphere | the (semisolid) layer below the lithosphere that forms the upper mantle |
| Inner core | the densest innermost layer of the Earth composed mostly of solid iron |
| Lithosphere | the outermost layer of Earth which comprises the crust and the upper (solid) mantle |
| Mantle | the thickest layer of Earth that is located outside of the outer core |
| Composition | the way in which a whole or mixture is made up |
| Outer core | the layer located around the inner core containing molten material |
| Plate | distinct sections of the lithosphere which make up the outermost layer of the Earth |
| Convection Currents | found in the Asthenosphere, causes tectonic plates to move |
| Continental crust | thicker part of Earth’s crust that forms the large land masses |
| Oceanic crust | thinner part of Earth’s crust that lies underneath the ocean basins |
