Stress & Strain
Mountains
Random
100
A condition of gravitational, and buoyant equilibrium between Earth's lithosphere and asthenosphere.
What is isostasy?
100
A form of ductile strain in which rock layers bend, usually as a result of compression.
What is a fold?
100
Materials that respond to stress by breaking or fracturing.
What is 'brittle'?
100
Large, flat areas of rock high above sea level.
What is a plateau?
100
Materials that respond to stress by bending or deforming without breaking.
What is 'ductile'?
200
The bending, tilting, and breaking of EEarth's crust; the change in shape or volume of rock in response to stress.
What is deformation?
200
The sloping sides of a fold.
What are limbs?
200
Stress that stretches and pulls a body apart.
What is tension?
200
It forms when rock layers are squeezed together and uplifted.
What are folded mountains?
200
It develops when steep faults break the crust into blocks and one block slips downward relative to the surrounding blocks.
What are grabens?
300
The movements of the lithosphere to reach isostasy.
What is isostatic adjustments?
300
Limbs meet at the bend in the rock layers.
What is a hinge?
300
Compression,tension, and shear stress.
What are the three types of stress?
300
The Hawaiian Islands are an example of this mountain.
What are volcanic mountains?
300
The black Hills of South Dakota and the Adirondack Mountains of New York.
What are examples of dome mountains?
400
As a mountain becomes smaller and lighter, the area may rise by isostatic adjustment in a process.
What is uplift?
400
A break in a body of rock along which one block slides relative to another; a form of brittle strain.
What is fault?
400
Temperature and pressure affect how rocks deform.
What are the factors that affect strain?
400
It forms where faults break Earth's crust into large blocks drop down relative to other blocks.
What is a fault-block mountain?
400
Brittle and ductile.
What are the types of permanent strain?
500
The added weight of the deposited material causes the ocean floor to sink by isostatic adjustment in a process.
What is subsidence?
500
The rock on either side of the fault plane of the fault plane slides horizontally in response to shear stress.
What is strike-slip?
500
During isostatic adjustments, the lithosphere sinks and rises atop the asthenosphere. As the lithosphere sinks, the rock in the crust is squeezed and the direction of stress changes.
What is an example of stress?
500
A range in California that contains many fault block mountains.
What is the Sierra Nevada range?
500
Challenge: It has been worn down by erosion. As the mountain shrinks, the crust underneath it is uplifted. (Hint available)
