A. Divergent plate boundary: region where rigid plates are moving away from each other

B. Transform plate boundary: boundary where plates slide past each other

C. Magnetic time scale: the history of magnetic reversals through time

D. Paleomagnetism: the natural remnant magnetism in rocks

E. Curie point: temperature above which a material loses its magnetization

F. Magnetometer: an instrument used to measure Earth's magnetic field

G. Normal polarity: a magnetic field that is the same as what exists at present

H. Litosphere: rigid outer layer of Earth including the crust and upper mantle

I. Reverse polarity: a magnetic field opposite what exists at present

J. Asthenosphere: "weak" layer within the mantle that is easily deformed

K. Convergent plate boundary: boundary in which two plates move toward each other, often resulting in collision or subduction

L. Magnetic reversal: change in the polarity of Earth's magnetic field over time intervals of roughly 200,000 years
