1. The Theory of Continental Drift

2. Objectives:
•Recreate Pangaea
•Explain how the first two(2)
evidences presented supported the
Continental Drift Theory

3. What is
PANGAEA?

6. •What feature of
picture helped you to
connect the pieces
perfectly?

7. “Drifted Supercontinent”
Objective: Reconstruct and describe Pangaea
Procedure:
1.) Refer to the displayed present world map.
2.) Each cut-out continents has already label in it.
3.)Paste the cut-out continents in a long
bondpaperin their respective positions.
4.) Continents must be closer to each other to recreate
a Pangaea.
5.) Questions displayed on the board must be discussed
within the group.
6.)Write your group number and members at the back
of your paper.

8. RUBRICS FOR SCORING OF THE
OUTPUT
•EXACTITUDE OF DATA -5 POINTS
5 pts-Continents are in their correct position are connected
4 -Continents are in their correct position but are not connected
3 -Continents are connected but not in correct position
•NEATNESS -2 pts.
2 -Cut-outs are not crumpled
•TEAMWORK -3 pts.
3 -maximum participation of members and tasks are divided
2 –half of the members have no participation
1 –only the leader and secretary are working
•TIMELINESS -3 pts
3 -the first to finish the task
2 -finishes on time
1 -finishes late
COMPREHENSION -2 pts
•2 POINTS FOR THE ASSIGNED QUESTION
TOTAL POINTS = 15pts

9. 1.Which continents do you think were
neighborsbefore?
2. What does the presence of Mesosaurus,
Cynognathusand Lystrosaurustells about
the initial location and positioning of South
America and Africa?
3.If Glossopteris were found in Antarctica,
what was the climate of the continent
before?
4. What are the two evidences that
supported the Continental Drift Theory
based on your activity?

10. The World

11. ALFRED WEGENER
THEORY OF CONTINENTAL
DRIFT
Found evidence for
PANGAEA and
proposed the theory of
continental drift.

12. Continental Drift
•Theory that continents were once
part of a single landmass that broke
apart and have moved to their
present locations.
•can drift apart from one another
and have done so in the past

13. Pangaea
Pangaea is the name given to the single
landmass that was present 250 million
years ago

14. Video

16. WEGENER’S EVIDENCE
1. APPARENT FIT OF THE CONTINENTS
Continents
“fit together”
like puzzle
pieces
Q1.Which continents do you think were neighbors before?

17. WEGENER’S EVIDENCE
2. FOSSIL
CORELATION
•fossils are remains
of living things that
lived long ago.
•similar fossils have
been discovered in
matching coastlines
on different
continents.

18. WEGENER’S EVIDENCE
Q.2What does the presence of Mesosaurus, Cynognathusand Lystrosaurus
tells about the initial location and positioning of South America and Africa?
Q3.If Glossopteris were found in Antarctica, what was the climate of the
continent before?

20. 1. APPARENT FIT OF THE CONTINENTS
2. FOSSIL CORRELATION
Q. 4. What are the two evidences that supported
the Continental Drift Theory based on your activity?

21. What the world would
look like million years from
now if the continents
continue to move?

22. Video

23. •Where do you think was the
Philippines located during the
time that Pangaea existed?
•Where is the Philippines located
at the present time?
•Where do you think Philippines
will be located 300 million years
from now?

24. •If you live in Wegener’s
time, are the two
evidences enough for
you to believe
him?Why?

25. •Study in advance the 3
rd
and 4
th
evidence
presented by Alfred Wegener in his Continental
Drift Theory.
3. PAST CLIMATE DATA
4. ROCK AND MOUNTAIN CORRELATION

26. Continuation: Day 2

27. Objectives:
•Explain how
•rock and mountain correlation
and
•.paleoclimatedata
supported the Continental Drift
Theory of Alfred Wegener

28. WEGENER’S EVIDENCE
•Mountains
•Some mountain ranges on different continents seem to
match.
•Ex: ranges in Canada match Norway and Sweden
•Northeastern parts of US and Canada & Northern Europe ranges
•Ex: Appalachian Mtn. match UK mtn

31. PALEOCLIMATE DATA
•Climatic evidence such as glaciers in areas that are
now close to the Equator

32. a. Glacial Striations
-when glaciers scratch the surfaces
of rocks and other things that
they float above of.
-found in middle of South
America and Central Africa that
are now close to the equators

33. b. Bituminous Coal
-a type of fossil fuel which is
made of compressed plant
remains
-Discovered in South America,
Africa,Indian subcontinent,
Southeast Asia and even in
Antarctica

35. The Plates Move…
So what now?
Which way?
•50 million years
