Geologic Time Scale/Continental Drift/Plate tectonics

How do matching rock formations on different continents provide evidence for continental drift?

• They show that all rocks are the same age

• They suggest that birds migrate across continents

• They indicate that the continents were once connected

• They prove that earthquakes are common worldwide
