What are some
similarities between
Continental Drift theory
and Plate Tectonics
theory?
What evidence do you see
in your “Reuniting
Pangaea” activity that
shows you the continents
were once connected?
Where are the oldest
fossils in a rock column
located?
How can you determine
which animal lived first
from a rock column?
The Theory that states that all
continents were once one large
continent (Pangaea) that broke apart
into the continents on Earth today.
1. Some continents fit together like jigsaw
pieces.
2. Matching fossils on Africa and South
America.
3. Matching mountain belts in Africa and
South America.
4. Glacier deposits in South America and
coal deposits in Antarctica.
5. Data showing that Greenland is moving.
Both help us to understand how
features (mountains, rift valleys, etc.)
have formed on continents and how
continents have moved.
Evidence from Reuniting Pangaea can be
found as…
1.
2.
3.
4.
Glossopteris
Lystrosaurus
Mesosaurus
Rock evidence
5. Cynoganthus
What are the five pieces
of evidence Wegener
used to support
Continental Drift theory?
What is Continental Drift?
How does sea-floor
spreading create midocean ridges?
What are the three types
of plate boundaries?
The three types of plate boundaries
are…
1. Divergent
2. Convergent
3. Transform
Sea –floor spreading happens at a
divergent boundary. When magma
pushes up from the divergent
boundary, it creates a mid-ocean
ridge.
The oldest fossils in a rock column
are found at the bottom.
You can determine which plant or
animal lived first by finding the
fossil that is lower in the rock
column.
Which direction do the
three plate boundaries
move?
Convergent boundaries create
mountain ranges by pushing two
pieces of continental crust together
and causing them to “build up.”
Which features are
associated with a
convergent boundary?
Divergent boundaries create rift
valleys because they are moving in
opposite directions and “tear” the
land between them.
Which features are
associated with a
divergent boundary?
Transform boundaries create
earthquakes when two plates push
past each other, catch, build up
energy, and release that energy
suddenly.
What is the only feature
of a transform boundary?
Convergent boundaries create
earthquakes, volcanoes, mountain
ranges, deep sea trenches and
subduction zones.
What is plate tectonics
theory?
Convergent → ←
Divergent ← →
Transform – sliding past each other
Transform boundary
(match the picture)
Transform boundaries create
earthquakes ONLY.
Convergent boundary
(match the picture)
Divergent boundaries create midocean ridges, sea-floor spreading
and earthquakes.
Divergent boundary
(match the picture)
How does a convergent
boundary create a
mountain range?
How does a divergent
boundary create a rift
valley?
The theory that states that the
Earth’s crust is divided into plates
that move around on the putty-like
mantle.
How does a transform
boundary create an
earthquake?
Where is the lithosphere
and what is it made of?
Convection currents happen in the
asthenosphere.
Where is the
asthenosphere and what
is it made of?
The asthenosphere is just below the
lithosphere. It is made of putty-like
liquid rock.
Where do convection
currents happen?
Convection currents move the plates
when the currents move the plates
like groceries on a conveyor belt.
How do convection
currents move the
plates?
The lithosphere is the layer of the
Earth below the crust that makes up
the tectonic plates. The lithosphere
is made of solid rock.
Weathering (match to the
picture)
Erosion (match to the
picture)
Explain weathering in the
picture.
Explain erosion in the
