Lithosphere
Crust and upper mantle
Middle Mantle
Toothpaste consistency, where convection currents take place (what causes plates to move), AKA the asthenosphere
Lower mantle
Lowest portion which remains liquid, very hot, makes up 55% of earth’s volume
Core
Large sphere of metal, mostly iron
Core
Temperature is about equal to the sun’s surface
Core
Split into two, outer and inner
Outer-core
Liquid iron
Inner-core
Solid iron, kept solid by intense pressure
