Station 1: Theory of Plate Tectonics

Lithosphere is broken up into many ___________.

Interaction between the plates causes _____ to move and __________ to expand

Earthquakes, __________, and other plate movement all caused by heat trying to escape from the Earth’s core

Station 2: Transform Boundary

Plates move _______ past each other

Many __________________

All these _______________ faults are called ____________________
o
(Use your webquest) A fault is_____________________________________________________

Example of transform boundary: __________________________________________

Example of transform boundary from your webquest:______________________________________________
Mini Lab: How would you move 2 graham crackers to simulate a transform boundary?

Describe the direction of the plate movement.

Describe what happened to the graham crackers (did they easily move past each other or was there some
resistance?)

Why do earthquakes occur here often? (Use your webquest to answer)

Why don’t you think volcanic eruptions happen here?

Station 3: Divergent boundary
Date __________________
Period __________

Plates move _______

Seafloor ___________ at the _____________________ is most common divergent boundary

A lot of __________ activity in the rift valley (opening between crust where magma pushes through).

Example of a seafloor divergent boundary is ______________________________.
o
Magma in the ________________________________ starts to push through and form a “break” called a
_____________________.
o
What is a rift? (Use your webquest) ______________________________________________________
_____________________________________________________________________________________________
Mini Lab: How would you move 2 fruit roll ups to simulate a divergent boundary?
o
Describe the direction of the plate movement.
o
Would there be earthquakes? Why?
o
Is there volcanic activity? Why?
label the parts

_________________________ boundary can form on a continent too.
o
Less common
o
When this happens a new _______________ forms.
o
Example is the _____________________________ in Africa.
What is Evidence of Sea Floor Spreading? —Think about your seafloor diagram to answer
1. Older rocks are ____________________ from the mid oceanic ridge on either side.
2._________________ ________________ is recorded in the rocks as iron is always pointed in the direction of
magnetic north, even when magnetic north switches directions.
Name _________________________________________
Station 4: Convergent boundary
Date __________________

_________ are pushed together

Features formed depends on which types of _______________ are converging
Period __________
A. Convergent (oceanic/continental crust)

________________ goes under _________ due
to greater ________ of oceanic crust.

__________ is created off the coast

__________ created on continental crust due to
rising magma.

Example of this type of convergent boundary is _______________________.
Mini Lab--How would you use a fruit roll up piece and a graham cracker piece to simulate this type of convergent
boundary?
o
What type of crust is the fruit roll up? Graham cracker?
o
What land form would form here?
o
Would there be earthquakes?Why?
o
Would there be volcanic activity?Why?
Station 5:
B. Convergent (oceanic/oceanic)

The _______________ oceanic plate will sink beneath the other

______________ is created in between the plates

An ___________________ is created due to the rising
magma.
o

What is an island arc? (Use your webquest)
An example of this type of convergent boundary is

Station 6: Subduction Zones (Use your webquest to answer questions)

Subduction Zones
What are they?

In ocean/continental plate collisions, which plate is subducted?
o

Period __________
Why?
In oceanic/oceanic plate collisions, which plate is subducted?
o
Why?

What occurs at subduction zones that is the opposite of seafloor spreading at divergent boundaries?

Place the terms next to the correct arrow: Subduction, Trench, Magma, Volcanic Mountain
Station 7:
C. Convergent (continental/continental)

The crust thickens as ________ are pushed upward.

_________________ ___________________ takes place.

An example of this type of convergent boundary would be ___________.
Mini Lab: Use two graham crackers and simulate this boundary.
o
What landform would form here?
o
Would there be earthquakes? Why?
o
Would there be volcanoes? Why?
o
Why is there no subduction zone here? (Use webquest for help)
