Evidence for Earth's Change/Plate Tectonics

Fossil records indicate that the continents were once connected. How do fossil records support this claim?

• We have been able to transport the same types of fossils from one continent to another.

• Fossils of the same organism have been found on continents that are now separated by oceans.

• Some continents contain fossils of many different types of organisms.
