What can you infer from the fact that fossils of tropical animals have been found in Antarctica? 

• The tropics were once located at the earth's southernmost point 
• . The Antarctic plate must have once been closer to the equator
• The volcanoes that once warmed Antarctica are now dormant

Where would you be most likely to find a boundary between a continental and an oceanic plate?

• In the center of the Pacific ocean 
• In the center of North America
• Off the West Coast of North America

How is a transform boundary different from a convergent boundary? 

• Plates move apart at transform boundaries, and toward each other at transverse boundaries
• Plates move underneath one another at transform boundaries, and over one another at convergent boundaries 
• Plates move toward each other at convergent boundaries, and side-to-side at transform boundaries
• Continental drift does not occur along convergent boundaries; it does occur at transform boundaries 

 What geological feature would you most likely find at a convergent boundary? 

• Mountains
• Islands
• Valleys
• Volcanoes
