What was the name of the supercontinent?

• The world
• Pangea
• Land
• Chick-Fil-A

What evidence helps scientists show how sea floor spreading occurs?

• Ocean Floor Material
• Magnetic Stripes
• Drilling Samples
• All of the Above

The similarity of fossils on different continents is strong evidence for:

• Continental drift and that land masses were once closer together

• Continental drift and that land masses were once further apart

• Plate tectonics theory of recycling crustal plates

• Alfred Wegener's theory of continental drift and divergent species

• Convection cells mixing the heat from the core to the surface of Earth
