Plate Tectonics Week 1

What is the theory that explains how Earth's continents have moved over time and were once joined together in a single landmass called Pangaea?

• Plate Tectonics

• Continental Drift

• Seafloor Spreading

• Magnetic Reversal

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

• A location where molten rock cools and hardens

• A place where two tectonic plates move away from each other

• A site of volcanic activity
