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 ocean currents
How do scientists use isochrons?
To predict earthquakes
To study the timing and spreading of the seafloor
To measure the Earth's temperature
To track animal migrations
What is a divergent boundary?
A place where two tectonic plates move toward each other
A location where molten rock cools and hardens
A place where two tectonic plates move away from each other
A site of volcanic activity
What can a rift valley eventually become?
A mountain range
