The name of the German Meteorologist that
Developed the theory of Continental Drift
Alfred Wegener
The super
continent that
existed 200-250
mya
Pangaea
These two
continents seem to
fit together like a
puzzle
South America
and Africa
Small freshwater reptile found
on South America and Africa
that helped support continental
drift
Mesosaurus
This tropical plant was
found on several
continents which helped
support continental drift
Glossopteris
The name of the naval
officer/scientist that came up
with the theory of how the
continents were moving
Harry Hess
Was proven that the rocks near
this point were younger than
rocks farther away from this
point
A ridge
This research vessel found
evidence that helped support
the idea that the seafloor was
spreading apart
The Glomar
Challenger
By studying the iron in the
rocks of the ocean floor
scientists found that this
unusual phenomenon was
happening
The Earth’s
magnetic north
pole is flipping
periodically
Tiny oceanic plate
subducting under
North American
plate feeding Mt.
St. Helens
Juan De Fuca
The surface of the
Earth is broken up
into several of
these.
Plates/Tectonic
Plates
The Himalayas are being formed
due to this type of boundary
Convergent
Boundary
Huge divergent
boundary located
in the Atlantic
Ocean
The Mid-Atlantic
Ridge
The San Andreas
Fault line is located
at this type of
boundary
Transform
Boundary
The area where one
plates is being
pushed under
another plate
Subduction Zone
The molten liquid portion of the
Earth’s interior
The Outer Core
Portion of the Earth that
consists of the Earth’s outer
crust and upper mantle
The Lithosphere
When an ocean plate and
continental plate collide, this
plate will subduct because it is
denser
Ocean Plate
Boundary between
the lower mantle
and outer core
Guttenberg
Discontinuity
The reason why it is so hot
deep within the Earth’s
mantle
Radioactive
Elements
When rocks fracture or break,
this is formed
A Fault
This type of forces squeezes
Rocks together
Compression
At a strike-slip fault the force
acting on the rock is a
____________force
Shear
The San Andreas fault line is an
example of this fault
A strike-slip
fault
Area where one plate is
subducting under another
plate is called an
oceanic__________.
Trench
Formed when two ocean plates
collide
Trench and
Volcanic Islands
Wegener believed the
continents were moving apart
because of this
Spinning of Earth on its axis
Mt. St. Helens was formed due
to this type of boundary
Convergent
Boundary
At a divergent boundary,
magma rises to the surface
because of
Change in
pressure
This scientist said the
continents are plowing
through the ocean floors
Alfred Wegener
Make your wager
Convection
currents within the
Earth’s mantle
Final Jeopardy
The leading theory behind
why the plates are moving
