What happens during a magnetic reversal?

• Earth's magnetic field disappears

• The North and South magnetic poles switch places

• The Earth's rotation stops

• The continents move rapidly

What is paleomagnetism?

• The study of ancient climates

• The study of how Earth's magnetic field is recorded in rocks

• The study of fossilized plants

• The study of ocean currents
