Lesson
1
Evidence of Plate Movements:
Continental Drift Theory
What’s In
Have you ever wondered how the continents were formed? Well,
if you say YES, then this module will help you find the answer to your
question. It will also help you to understand how plate moves and also
the different theories.
What’s New
Continental Drift Theory
Look at the figure below. As years passed by, do you agree that
continents drift as what was shown in the picture? If YES, then you
might agree or believe to Alfred Wegener.
Alfred Wegener, a German
meteorologist, proposed that the
continents were once one large
landmass
called
PANGAEA”
which
means
“All
Earth”.
Pangaea broke into two smaller
supercontinent called Laurasia
and Gondwanaland. Continents
further broke and are slowly
drifting around the Earth. He
proposed the Continental Drift
Theory. What are the evidences
that supported the continental
drift theory?

What is It
EVIDENCES:
Continental Jigsaw Puzzle
The edge of one continent matches
the edge of one another. Africa and
South America fit together; Europe and
North America, India, Antarctica and
Australia match one another.
https://www.thinglink.com/scene/716674018916171777
Fossils
Fossils are preserved remains or
traces of organisms from the past. Similar
fossils found in places he thought were
once connected
like GLOSSOPTERIS
(extinct plant) were located in the
continents of
South Africa, Australia,
India, Antarctica. LYSTROSAURUS found
at
Africa,
Antarctica
&
India.
CYNOGNATHUS – found at South Africa &
Africa. MESOSAURUS (Freshwater
dinosaur) South America & Africa.
http://publish.illinois.edu/alfredwegener/evidence/
Rocks
Fossils found in rocks support the
Continental
Drift
Theory.
The
rocks
themselves also provide evidence that
continents drifted apart from each other.
http://publish.illinois.edu/alfredwegener/evidence/
Similar layers of rock were formed in
Antarctica, Australia, South America, Africa,
and India before Pangaea broke apart.
Glossopteris fossils were found in the rocks on
each continent. Mountain ranges appear to be
continuous on neighboring continents
9
Glaciers
Glaciers carve rocks and leave marks
as they move. In this evidence, scientists
can determine the direction of movement of
each continent.
Coal deposits in Antarctica means
that it must have been positioned in a part
of the Earth where it once support life. This
leads to the idea that Antarctica was once
located near the region of the Earth with
tropical climate.

Evidence of Plate Movements:
Seafloor Spreading Theory
What’s In
Despite the evidences presented by Alfred Wegener, his idea that
the continents were once joined together was not accepted by scientific
society because he was not able to explain how this drifting took place.
In this lesson, you will learn about the Seafloor Spreading Theory
that will strongly support the idea that continents are drifting and find
out the site of origin of plate movements.
What’s New
https://theconversation.com/marie-tharp-pioneered-mapping-the-bottom-of-the-ocean-6decades-ago-scientists-are-still-learning-about-earths-last-frontier-142451
Seafloor Spreading Theory
Harry Hess together with Robert Dietz suggested an explanation
to the continental drift theory. This is the Seafloor spreading Theory,
process by which new ocean sea floor is formed near the mid-ocean
ridge and moves outward. Hot less dense material from below the
earth’s crust rises towards the surface at the mid – ocean ridge.
14
What is It
Subduction
As new ocean floor is created
by sea-floor spreading at the midoceanic ridges it is consumed at
the subduction zones where the
lithosphere sinks under the
asthenosphere
https://www.medellin.unal.edu.co/~rrodriguez/geologia
/ofiolitas/Introduction%20to%20Plate%20Tectonics.htm
Findings that support Seafloor Spreading Theory:
1. Rocks are younger at the mid-ocean ridge.
2. Rocks far from the mid-ocean ridge are older.
3. Sediments are thinner at the ridge.
4. Rocks at the ocean floor are younger than those
at the continents.
https://image.slidesharecdn.com/seafloorspreadingtheorydiscu
ss3-160802131934/95/seafloor-spreading-theory-discuss-3-31638.jpg?cb=1516545491
Harry Hess observed that the rate of formation of new seafloor at the
mid-ocean ridge is not always as fast as the destruction of the old seafloor at
the subduction zone. This explains why the Pacific Ocean is getting smaller
and why the Atlantic Ocean is getting wider. If the subduction zone is faster
than the seafloor spreading, the ocean shrinks. He published his theory in
History of Ocean Basins (1962), and it came to be called "seafloor spreading."
15
In the early 1960s, dating of ocean-core samples showed that the ocean
floor was younger at the Mid-Atlantic Ridge but progressively older in either
direction, confirming the reality of seafloor spreading.
What’s More
To further understand the idea of Harry Hess, perform the activity
below to learn about the other evidence of Seafloor Spreading Theory.
Modeling Sea Floor Spreading
Materials
Cardboard
Procedure
Scissors
Paper
Colored pencil or crayons
Part 1
1. To create a working model of sea floor spreading, follow the model
seen below (Figure 1). The base is best if made from poster board or
card stock. The width and length of the base are not critical, as long
as they are at least 12 cm wide and 30 cm long. Cut 3 slits, each
slightly more than 8 cm wide. One slit needs to be in the center, and
the other two at either end of the base, at least 4 cm in from the ends.
Label the slits A and B at either end.
2. Cut out the plate strips and place them back-to-back (marked sides
together with number 1 at the top) and tape the end as indicated (at
the end nearest number 7.)
3. Shade alternating strips to represent the reversals of the earth’s
magnetic field. Be sure that the shading on either side of the strip
match the alternate side.
4. Put the two strips up through the bottom slit and then off to the slits
at either end of the base. (Figure 2.)
5. Thread the two strips through the center slit of the base, keeping the
taped edge at the bottom. Pull the “North American Plate” strip down
through slit “A” and the “Eurasian Plate” strip through slit “B”.
16
6. Push the strips up from below until you can see numbers 3, 4, and 5
on top of the base.
Templates for plate strips
1. What does the center slit in the model represent?
2. What do the strips of paper represent?
3. Based on your understanding of Seafloor Spreading, does the earth get
bigger? Why or Why Not?
17
Lesson
3
Evidence of Plate Movements:
Magnetic Reversal
What’s New
Magnetic Reversal
Magnetic Reversal also called magnetic ‘flip’ of the Earth. It happens
when the North Pole is transformed into a South Pole and the South Pole
becomes the North Pole. This is due to the change in the direction of flow in
the outer core.
What is It
Paleomagnetism confirms the seafloor spreading hypothesis
 Geomagnetic field switches from reversed
polarity to normal polarity on irregular basis
 Iron crystals in magma incorporate Earth’s
new magnetic orientation
 Iron-rich sediment particles align with
geomagnetic field like compass needles
http://www.eniscuola.net/en/2017/01/09/at-theorigin-of-rocks-the-secrets-of-paleomagnetism/
Geologists used magnetometers to conduct studies in the 1950’s and
were amazed that polarity had reversed many times in the past.
Two or more plates pull apart. Molten
material rises through Rift Zone. Newest
magma on either side of rift. Like conveyer
belts, the newer crust travels away from the
center on each side. Oceanic crust records
reversed and normal polarity episodes.

What I Have Learned
Direction: Write TRUE if the statement is correct and FALSE if the
statement is wrong on the column provided for every item.
No.
Statement

2
Magnetic Reversal is also called magnetic flip.
The OLDEST seafloor is located closest to the mid ocean
ridge.
A device used by scientists to have a clearer view of the
ocean floors is called Radar.
Subduction is the process by which the ocean floor sinks
beneath a deep ocean trench and back into the mantle.
The COOLEST seafloor temperature is located farthest
from the mid ocean ridge.
Year 1990 was when seafloor spreading theory was
proposed.
The deepest part of the ocean is called trenches.
The oceanic crust expands when it reaches the
continental crust.
Harry Hess and Alfred Wegener proposed the theory of
seafloor spreading.
Changes in magnetic polarity occur because the magnetic
poles switch positions.
Seafloor spreading is when new seafloor is formed as
magma is forced upward.
Rock shapes in the mid ocean ridge is one evidence of sea
floor spreading.
If subduction is faster than seafloor spreading, the ocean
gets wider.
Youngest rocks were always at the center of the ridges.
Ocean floors keep spreading, so all oceans are getting
bigger.
