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 |
