CONVECTION CURRENTS
ASTHENOSPHERE
thin laters
LUBRICANT- allows lithosphere to slide on top of it
Semi-molten
LITHOSPHERE
sits on Asethenosphere - SLIDES
MOHO - boundary where it meets crust
solid +rigid - brittle
cracked - plates
CRUST
outer layer - solid rock
CONTINENTAL CRUST
OCEANIC CRUST
CORE
INNER CORE
nickel + iron
solid - intense pressure
transfers heat to upper layers
Outer core
nickel + iron
intense heat - fully molten
spins around static inner core
