PLATE TECTONICS
100
When rocks change shape and size.
Deformation
100
These faults move towards one another. One fault block rises above the other fault block.
Reverse Fault
100
This stress results in rock being squeezed together.
Compression
100
This type of mountain is eruptive.
Volcanic

What are the three compositional layers of Earth.
Crust, Mantle, Core
100
What are the mechanisms that have been proposed to explain the movement of Earth’s tectonic plates?
mantle convection, ridge push, and slab pull
200
When rock layers bend under stress.
Folding
200
This fault forms when rocks break and move past one another horizontally.
Strike Slip Fault
200
This stress results in rocks passing by one another horizontally.
Shear Stress
200
This type of mountain contains many anticlines and synclines.
Folded.
200
What is the process of sediment being transported from one place to another.
Erosion
200
Satellites can measure the small distances that GPS ground stations move over time. In what units is the movement of tectonic plates measured?
centimeters/year
300
When rocks break due to stress and pass by one another, they form...
Faults
300
This fault forms when fault blocks pull apart.
Normal Fault
300
This type of stress occurs when rocks are pulled apart.
Tension
300
This type of mountain contains many normal faults.
Fault Block
300
What are the three types of plate boundaries?
Convergent, Divergent, Transform
300
HOW ARE CONTINENTAL CRUST AND OCEANIC CRUST DIFFER?
OCEANIC CRUST IS THINNER.
400
What are the two types of folds?
Syncline Anticline
400
Which fault would result in an earthquake?
Strike Slip
400

The Appalachian Mountains formed when the North American Plate collided with the African plate years ago. What type of mountain would this be?
Folded
400
This process is what allows rock to move in the mantle.
Convection
400
According to this map, where can you infer that mountains are being formed?
between the Cocos Plate and the Caribbean Plate
500
What zone do volcanoes form in?
Subduction Zone
500
What are the three main parts of a fault called?
hanging wall, fault plane, footwall
500
Can tension, compression, and shear stress all occur at the same time? Why/why not?
No
500
Describe how a fault-block mountain forms.
Normal faults pull apart and pieces of land begin to drop.
500
What is the chemical that is found in lava that can make it faster or slower?
Silica
500
Over long periods of time, tectonic forces can cause rocks to fold. What kind of stress causes folding?
compression
600
Two fault blocks move past each other horizontally.
Strike \-slip fault.
600
the first fold, the rocks get younger the farther they are away from the center of the fold. In the second fold you observe that the rocks get older the farther they are away from the center
The first fold is the syncline AND THE SECOND FOLD IS THE ANTICLINE.

This diagram shows the formation of fault-block mountains. The arrows show the direction of force. The curving line on the top of each figure depicts a river.
What does the letter L represent?
THE HANGING WALL.

NAME THE 3 TYPES OF LATE BOUNDARIES AND DESCRIBE THEM.
TRANSFORM - PLATES SLIDE PAST EACH OTHER.
CONVERGENT - PLATES MOVE TOWARD EACH OTHER.
DIVERGENT - PLATES MOVE AWAY FROM EACH OTHER.
