Activity No. 4 Drifted Super Continental

- The document discusses a group activity on continental drift where students drew fossils found in present continents to reconstruct the positions of continents in the past. - Evidence like the distribution of Glossopteris fossils and Mesosaurus fossils found in different continents indicate that they were once connected in a supercontinent called Pangaea approximately 250 million years ago. - By matching the shapes of continent edges and distribution of fossils between continents, it can be inferred that Australia and Antarctica as well as Africa and South America were once neighboring landmasses before continental drift separated them. - In 100 million years, the Philippines may be located closer to the center of the Pacific Ocean as the plates continue to move.

Activity No. 4

Drifted Super Continental

I. Objectives
- Tell the possible direction of motion of the continents as they drifted away.
- Draw fossils of plants and animals as evidences found in the present continents that will
help solve the puzzle in the fitting of the drifted continents.
- Reconstruct and describe Pangaea.
- Predict what will happen to the world as the continents continuously move.

II. Materials
- Photocopy of the Seven Continents
- World Map
- Pair of Scissors

III. Observations

Q13. What does the Glossopteris fossils tell us about the early positions of the continents?

 The distribution of fossils in different continents is the most visible evidence that the continents
were once connected.

Q14. If Glossopteris fossils were found in Antarctica, what does this indicate about the climate of this
continent before?

 Glossopteris fossils are types of plants that only grows in a warm climate. Therefore, Antarctica
probably had this type of climate before.
Q15. If the climate and the position of a place are relative to each other, where then was the initial
location of Antarctica 250 million years ago?

 If climate and the location of a place is related, the initial location of Antarctica 250 million years
ago must have been somewhere away from the poles.

Q16. What does the presence of Mesosaurus fossils tell about the initial location and position of South
America, Africa, and Antarctica?

 The presence of Mesosaurus fossils tells us that South America, Africa and Antarctica were once
connected before and was once a big landmass because it is impossible for these reptiles to
swim over the vast oceans and move from one continent to another.

Q17. What clues are useful in reconstructing Pangaea?

 The clues that are useful in reconstructing Pangea are their shapes, the edges of the continent
that matches the edge of another, the distribution of fossils and rock features.

Q18. Which continents do you think were neighbors before?

 Based on our observations during the activity we conducted, we think that Australia and
Antarctica are neighboring continents. So as Africa and South America, Australia and Antarctica.

Q19. Will there be a possibility that the current location of a continent would be different 100 years
from now?

 There is a possibility that the location of a continent won’t be the same in 100 years’ time
because plates are continuously moving. It may be not that evident because this would take
millions of years to be noticeable enough.

Q20. Where do you think was the Philippines located during the time that the Pangaea existed?
Research on how the Philippine islands emerged.

 The islands that make up the Philippine archipelago are classified as island arcs which are
formed due to subduction. Thus, Philippines probably wasn’t even present the time Pangaea
existed but emerged as a result of the plates’ movement and volcanic eruptions.

Q21. If the continents will continue to move, try to predict the Philippines’ location 100 million years
from now.

 If the continents will continue to move, the Philippines would probably be moved closer towards
the center part of the Pacific Ocean.

Conclusion:

Hence, as the continents drifted away from each other, it travels in a random direction. Continuous
continental drift may trigger the formation of new land forms such as mountains and may cause natural
disasters like earthquakes and tsunamis. Geographical positions of countries can also be changed as the
continents continue to move.
