What name did Wegener give the supercontinent in his Continental Drift Theory?
Pangaea
Which layer of the Earth do you stand on?
The crust
The majority of earthquakes and volcanoes occur along _____.
Plate Boundaries
True or False: Wegener said that the mountains (rocks) in North America line up with mountains (rocks) in northern Europe.
True
