The document discusses evidence that supports the continental drift theory proposed by Alfred Wegener. It describes an activity where students reconstruct the supercontinent Pangaea by fitting together continent landmass cutouts. The activity aims to showcase two key evidence: 1) the apparent fit of continents and 2) fossil correlations found across different continents. It also discusses two additional evidence put forth by Wegener: 3) past climate data like glacial striations found in present-day equatorial regions, and 4) correlations between mountain ranges and rock formations between separated continents.
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
bondpaper in 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

COMPREHENSION - 2 pts
• 2 POINTS FOR THE ASSIGNED QUESTION
TOTAL POINTS = 15pts
9. 1.Which continents do you think were
neighbors before?
2. What does the presence of Mesosaurus,
Cynognathus and Lystrosaurus tells 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?
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
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?
18. WEGENER’S EVIDENCE
Q.2What does the presence of Mesosaurus, Cynognathus and Lystrosaurus
tells about the initial location and positioning of South America and Africa?
Q 3.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?
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 3rd and 4th evidence
presented by Alfred Wegener in his Continental
Drift Theory.
3. PAST CLIMATE DATA
4. ROCK AND MOUNTAIN CORRELATION
27. Objectives:
• Explain how
• rock and mountain correlation
and
•.paleoclimate data
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
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
