QUESTION
The oceanic crust is made mostly of the rock
______________.
Continental crust is made mostly of the rock
___________.
Transforms faults can be identified by the
___________ they cause.
The Hawaiian Islands are an example of ______
_________ volcanoes.
What is the stress force called that pushes rock in
two opposite directions?
What theory states that pieces of Earths lithosphere
are in constant, slow motion?
Volcanic belts can form along __________
boundaries.
___________ ____________ in the asthenosphere
cause the Earth’s plates to move.
The place where to plates come together is called a
____________ ______________.
Why is there a high risk of earthquakes along the
Pacific Coast of the United States?
What landform is formed on top of a mantle plume
hot spot?
Which is more dense: old oceanic crust or young
oceanic crust? Why?
What are the two types of crust?
What is an island arc and how is it related to plate
tectonics?
What is the place where two plates slip past each
other in opposite directions called?
How does a trench form?
What is subduction?
ANSWER
basalt
granite
Earthquakes
Hot spot
Shearing
The theory of plate tectonics
Convergent
Convection currents
Convergent boundary
Because the North American Plate and Pacific Plate
meet here
Volcanic islands
Old – because it is cooler making it more dense
Oceanic crust and continental crust
A chain of volcanic islands; it forms where oceanicoceanic crust convergies
Transform boundary
When oceanic crust subducts under another plate
The process where the more dense plate is forced under
another plate and melts back into the mantle to be
recycled
18. What landform is created at a divergent boundary Rift valley
on land?
19. How do mountains form?
Convergent boundaries of continental – continental
crust or continental-oceanic crust or at the mid-ocean
ridge at diverging oceanic-oceanic crust
20. Draw what happens when a rock is put under
compression.
21. Draw what happens when a rock is put under
tension.
22. Draw what happens when a rock is put under the
stress of shearing.
23. What plate boundary is compression associated Convergent boundary
with?
24. What plate boundary is tension associated with?
Divergent boundary
25. What plate boundary is shearing associated with?
Transform boundary
