Which of the following best explains why Pangea broke apart into modern day continents?

• Earthquakes and volcanoes formed between the continents.

• Changing climate caused ice to form between the plates.

• Balanced forces caused a change in the motion of the plates.

Alfred Wegener noted that fossils from a particular type of reptile were found on both sides of the Atlantic Ocean. Which of the following would be the best explanation of how this occurred?

What is occurring as a result of the plate collision?

• A mid-ocean ridge is forming.

• Subduction is occurring because oceanic crust is denser than continental crust.

• A divergent boundary is forming.

• A transform boundary is forming due to two plates sliding past one another.

The Aleutian Arc is a distinguishing feature of the state of Alaska illustrated above. Alaska is part of the North American Plate. To the South of the Aleutian Arc is the Pacific Plate. The Aleutian Arc was formed as the Pacific Plate traveled North and the North American Plate traveled West.

Based on the information above, which type of plate boundary caused the formation of the Aleutian Arc?

• Divergent Boundary

• Transform Boundary

• Convergent Boundary

• Strike-Slip Fault Boundary
