The Breakup of Pangaea
Directions: Go to the website,
http://www.exploratorium.edu/origins/antarctica/ideas/gondwana2.html to use an interactive map
to answer the questions below about Pangaea and Continental Drift.
Theory of Continental Drift
1. Around how long ago did the supercontinent Pangaea begin to split apart?
2. What is the maximum distance tectonic plates will travel in a year?
3. What are the names of the two halves created when Pangaea split?
Continental Puzzle
4. What two continents did Wegener recognize fit together almost like a puzzle?
Fossils
5. What evidence about fossils in Antarctica leads to the theory that the southern
continents once formed the continuous supercontinent Gondwandland
More Fossils
6. What evidence has been found in Antarctica to suggest that it was not always the
cool, frigid climate it is currently?
7. What life forms are currently found on Antarctica today?

Pd:
Tillite
8. What is tillite and in what continents is it found?
Andean Mountains
9. The Andean Mountains found in South America are believed to be part of a
mountain chain formerly connected with what continent?
Time Periods
10. What are the 5 time periods since the breakup of Pangaea?
Critical Thinking Questions:
1. In a few sentences, explain which piece of evidence you believe is most supportive of
the Continental Drift theory and explain why.
2. Looking at the main diagram on this interactive site, which “part” of Pangea are we
looking at? List the current continents shown on this diagram and indicate which
direction they are moving.
3. Using the time period bar listed below, examine the speed at which the plates are
moving. If the plates continue to move at the same rate in the same directions,
explain what will eventually happen and estimate when this will occur.
