How is density defined?

• Quantity of mass per unit volume.

• How much space an object takes up

• The total mass of an object

This is the portion of the upper mantle which is described as having a "plastic like" motion.

• Lithosphere

• Asthenosphere

• Mantle

• Convection Currents

This is the crust and the upper most mantle, it is brittle and rigid.

• Lithosphere

• Asthenosphere

• Mantle

• Convection Currents
