• Crust- rigid, rocky outer surface of the Earth, composed mostly of basalt and granite. Thinner under oceans
• Continental Crust- thick parts of the Earths crust not located under ocean.
• Lithosphere- crust, plus rigid, upper mantle• Oceanic crust- thin parts of Earth’s crust under
oceans.• Ocean- Large bodies of water, sitting atop
oceanic crust. • Mohorovicic Discontinuity- separates crust
and upper mantle

• Mantle- rocky layer located under crust- composed of silicon, oxygen, magnesium, iron, aluminum, and calcium. Convection (heat) currents carry heat from the inner mantle to the cooler outer mantle.
• Upper mantle- (rigid) uppermost part of the mantle, part of lithosphere.
• Upper mantle (flowing) Athenosphere- lower part of the upper mantle that exhibits plastic (flowing) characteristics.
• Asthenosphere- Layer in upper mantle that is made of material that can be reshaped and deformed and on which the continental plates move.

• Lower mantle- (semi-rigid) deepest part of the mantle, just above core.
• Outer core- Molten iron-nickel layer that surrounds the inner core.
• Inner core- solid iron-nickel center of the Earth, very hot and under great pressure.
