The Continental Drift Theory In 1596, Abraham Ortelius (1527-1598), a Flemish cartographer, observed that the shapes of the continents seem to fit together. With the absence of valid measurements and proofs, the only speculation Ortelius could provide was that earthquakes and flooding may have made the separation possible.

1. Lord, true source of light and wisdom, give us
a keen sense of understanding, a retentive
memory, and a capacity to grasp things
correctly. Grant us the grace to be accurate in
our expositions and the skill to express
ourselves with thoroughness and clarity. Be
with us today at the start of our work, guide
its progress and bring it to completion. Grant
this through Christ, our Lord. Amen.

they are look like for the last year you saw them.
They are much different, right? Write Two
reasons why don’t you notice that?

11. • In 1596, Abraham Ortelius
(1527-1598), a Flemish
cartographer, observed that
the shapes of the continents
seem to fit together. With the
absence of valid
measurements and proofs, the
only speculation Ortelius could
provide was that earthquakes
and flooding may have made
the separation possible.

18. What Is Pangaea?
About 200 million years ago, all the continents were
connected together as one giant supercontinent known as
Pangaea. Over time, these continents have broken apart into 7
continents and 5 oceans.

19. Alfred Wegener’s supercontinent theory “Pangaea”
•In 1912, Alfred Wegener thought that all continents were
connected as one giant landmass called “Pangaea”
•Developed the concept and hypothesized the continental
drift theory.
•He also introduced the idea that 200 million years ago,
Pangaea tore apart. It was plate tectonics that drove
continental drift and the moving of continents.

20. LAURASIA: Laurasia is comprised
of today’s North America, Europe,
Greenland, and Asia in the north.
GONDWANA: Gondwana was
pieced together with present-day
Africa, South America, Australia,
and Antarctica.

21. Eduard Suess’ supercontinent theory of “Gondwana”
•He proposed the world was all
connected as one giant continent
“Gondwana” at one time. He also
theorized that there was one giant
ocean – “Tethys Ocean”

22. 1. Similarity of fossils found in different continents
•Fossils of the seed
fern Glossopteris were too heavy to
be carried so far by wind.
•Mesosaurus was a swimming
reptile but could only swim in fresh
water.
•Cynognathus and Lystrosaurus we
re land reptiles and were unable to
swim

23. 2. Presence of coal seams in polar regions.
Grooves and rock deposits left by ancient glaciers are found
today on different continents very close to the equator. This
would indicate that the glaciers either formed in the middle of the
ocean and/or covered most of the Earth. Today glaciers only
form on land and nearer the poles. Wegener thought that the
glaciers were centered over the southern land mass close to the
South Pole and the continents moved to their present positions
later on.

24. 3. Similarity of Rock types in different continents
•Identical rocks, of the same type and age, are
found on both sides of the Atlantic Ocean.
Wegener said the rocks had formed side-by-side
and that the land had since moved apart.

25. •Mountain ranges with the same
rock types, structures, and ages
are now on opposite sides of the
Atlantic Ocean. The Appalachians
of the eastern United States and
Canada, for example, are just like
mountain ranges in eastern
Greenland, Ireland, Great Britain,
and Norway. Wegener concluded
that they formed as a single
mountain range that was
separated as the continents
drifted.
4. Continuity of rock layers found in different continents

26. Let every created things give
praise to the LORD, for He
issued His command, and they
came into being. Psalms 148:5

27. Make a graphic organizer summarizing the evidences of plate
tectonics.
Example:

28. Reflective Question
1. How have advancements in technology, such as GPS and
satellite imagery, contributed to our ability to gather evidence
for the movement of continents over time?
2. In your opinion, which piece of evidence for continental drift is
the most convincing, and why?
