Explain paleomagnetism and why it is important.
The study of ancient magnetism preserved in rock and helps support the sea floor spreading theory.

Explain isostasy.
Isostasy is the rising or settling of a portion of the Earth's lithosphere that occurs when weight is removed or added in order to maintain equilibrium between buoyancy forces that push the lithosphere upward and gravity forces that pull the lithosphere downward.
