Which of the following was NOT an evidence that Wegener used to support Continental Drift?

• Shape of Continents

• Geologic evidence

• Fossil evidence

• Convection currents

How did Wegener explain that fossils of the same land dwelling reptile appeared on the coastlines of two distant continents?

• The continents were once joined together. As they separated, they took the dinosaur fossils with them.

• The dinosaurs evolved independently on multiple continents.

• The land reptile walked across land bridges that stretched across the Atlantic ocean.

• The land reptile swam across the Atlantic ocean.
