P A N G A E A .
This is referred to as the waters surrounding Pangaea:
P _ _ T _ _ L _ _ _ _ .
P A N T H A L A S S A .

a) one
b) all
c) whole
b) all
The “GAEA” in Pangaea means:

This is referred to as the theory that is originated by Alfred Wegener:
C _ _ T _ _ _ _ T _ _ D _ _ _ T
C O N T I N E N T A L D R I F T .
Which is NOT the reason why Wegener’s Continental Drift Theory was rejected?
a) He explained fossil similarities based on land bridges, but not founded because some land bridges had eroded or sunk into the seas.
b) His handwriting was not legible.
c) He thought that continents were moving at a rapid rate.
b) His handwriting was not legible.
What are the two major forces that make massive plates move?
D _ _ _ _ _ _ and R _ _ _ _ _ _ _ _ forces.
Driving and Resisting forces.
These four are part of Driving Forces:
M.S.S.R.
Mantle Convection
Slab Pull
Slab Suction
Ridge Push
These four are part of Resisting Forces:
S.C.T.D.
Slab Resistance
Collisional Resistance
Transform Fault Resistance
Drag Force
ALONG THE PLATE EDGE:
These are the four discussed theories on Earth’s Movements:
C. C. S. T.
Contraction Theory
Continental Drift Theory
Seafloor Spreading Theory
Theory of Tectonic Plates
ALONG THE PLATE EDGE:
This is the theory that is originated by Edward Suess:
C _ _ T _ _ _ _ I _ N T _ _ _ R _
C O N T R A C T I O N T H E O R Y .
ALONG THE PLATE EDGE:
The Contraction Theory refers to the other feature of the Earth forming during one cooling event.
TRUE or FALSE?
TRUE.
ALONG THE PLATE EDGE:
This is the process of forming mountains and mountain ranges, and is caused by collision of plates and forces of compression.
a) Orogenesis
b) Oroexodus
c) Oroleviticus
a) Orogenesis
ALONG THE PLATE EDGE:
According to Wegener’s Continental Drift Theory, how many millimeters of movement per year is observed, based on his what he theorized?
a) 13 mm
b) 15 mm
c) 18 mm
b) 15 mm
ALONG THE PLATE EDGE:
He is the person who discovered the Seafloor Spreading Theory:
a) Harry Styles
b) Harry Hess
c) Edward Suess
b) Harry Hess
ALONG THE PLATE EDGE:
The Seafloor Spreading Theory refers to the moving of the ocean floors.
TRUE or FALSE?
TRUE.
This theory incorporates the Seafloor Spreading and the Continental Drift Theory:
The Theory of T _ _ _ _ N _ C P _ _ _ _ _ .
The theory of Tectonic Plates.
Which two words among these seven words… are not included in the 15 major tectonic plates?
Australian Pacific Singaporean Caribbean Nazca Indian Spanish
Singaporean and Spanish are not included in the 15 major tectonic plates.
This refers to regions that are between plates:
P _ _ _ _ B _ _ _ _ _ R _ _ S .
P L A T E B O U N D A R I E S .
There are three kinds of plate boundaries, and those are:
D. C. T.
Divergent
Convergent
Transform
These refer to the fractures on
Earth’s crust that develop
as plates move:
a) Reasons
b) Faults
c) Explanations
b) Faults
This type of plate boundary has a spreading motion and a constructive effect:
a) Divergent
b) Convergent
c) Transform
a) Divergent
This type of plate boundary has a subducting motion and a destructive effect:
a) Divergent
b) Convergent
c) Transform
b) Convergent
This type of plate boundary has a lateral sliding motion and a conservative effect. This is the only type of plate boundary that has no volcanic activity.
a) Divergent
b) Convergent
c) Transform
c) Transform
