I know my boundaries for
100
This type of plate boundary occurs when two
plates slide past each other forming a zigzag
plate margin. The San Andreas Fault in California
is an example of a ______ boundary.
I know my boundaries for
100
What are Transform Boundaries?
I know my boundaries for
200
These are boundaries where plates
move together and form a collision
or subduction zone.
I know my boundaries for
200
What are
Convergent Boundaries
I know my boundaries 300
These boundaries are created when plates move
apart and new material is added to the Earth’s
crust. An example is the Mid-Atlantic Ridge.

What are earthquakes?
Boundaries-2 for 100
When an oceanic plate collides with a
continental plate deep trenches may
form. The most famous of these is an
11,000 meter deep trench called the
_________.

What is
The Marianas Trench?
Boundaries-2 for 200
When plates collide, one plate may
slide beneath another creating an area
called a __________ zone.

Volcanic arcs and oceanic trenches
encircle the Pacific Basin creating a
zone of frequent earthquakes and
volcanic eruptions. This large area
of convergence and subduction is
called _________ ________ ___
__________.

History of Tectonics for 100
The theory that the continents are
constantly moving over the surface of
the earth is called:
History of Tectonics for 100
What is
The Theory of Continental Drift?
History of Tectonics for 200
The scientist who proposed that the
continents were once part of a super
continent.
History of Tectonics for 200
Who is
Alfred Wegner?
History of Tectonics for 300
The name of the super continent
theorized by Alfred Wegner.
History of Tectonics for 300
What is Pangaea?
History of Tectonics for 400
When Paleontologists found evidence of
similar __________ on continents
separated by great geographic distance,
the idea of a super continent Pangaea
was supported.
History of Tectonics for 400
What are species or fossils?
History of Tectonics for 500
Scientists studying
_______________, the detection of
the Earth’s movement, proved that
earthquakes and volcanoes seem to
align along belts that define the
tectonic plates.

What is Seismology?
The Earth's Layers for 100
The continents and the oceans are part of
this layer of the earth’s surface. It is the
lightest layer of the Earth.
The Earth's Layers for 100
What is the Crust?
The Earth's Layers for 200
A semi-liquid layer of the Mantle just
under the lithosphere that flows as a
result of convection currents and causes
plates to move.
The Earth's Layers for 200
What is the aesthenosphere?
The Earth's Layers for 300
Fluid movements just below the
lithosphere that causes earthquakes,
mountain building and volcanoes.
The Earth's Layers for 300
What are convection currents?
The Earth's Layers for 400
This layer is composed of solid iron and
nickel. Although it is the smallest layer, it
is the heaviest.
The Earth's Layers for 400
What is the inner core?
The Earth's Layers for 500
Between the mantle and the inner core,
this layer is liquid iron and nickel.
The Earth's Layers for 500
What is the outer core?
Fact Maniac for 100
Most of these are due to the release of
built-up energy along plate boundaries.
When the pressure on a fault overcomes
the friction on a fault, this occurs.
Fact Maniac for 100
What is an earthquake?
Fact Maniac for 200
Earthquakes release energy in the form
of these
Fact Maniac for 200
What are
primary and secondary waves?
Fact Maniac for 300
The amount of energy released during an
Earthquake is measured by seismographs
and reported as _____________.
Fact Maniac for 300
What is magnitude?
Fact Maniac for 400
Inside the earth’s core, a reaction occurs
which that breaks heavy element into
smaller pieces causing a chain reaction.
This event is called
Fact Maniac for 400
What is Fission?
Fact Maniac for 500
Scientists believe that these reactions
inside the Earth’s core create convection
currents that move Earth’s plates.
Fact Maniac for 500
