Faults and Boundaries
This type of boundary is where two plates move apart.
What is a divergent boundary?
The resistance of a liquid material.
What is viscosity?
A place on the fault where the 1st motion occurs.
What is the focus?
The process in which rocks change shape under stress.
What is deformation?
Magma that has reached the surface.
What is lava?
This type of boundary is where two plates come together.
What is a convergent boundary?
It is melted rock and less dense than solid rock
What is magma?
This is located directly above the focus.
What is the epicenter?
This occurs when rock layer bend under stress.
What is folding?
A type of stress that squeezes or pushes rocks together.
What is compression?
This type of boundary is where two plates move past each other.
What is pyroclastic material?
A ground motion that occurs when rocks in the Earth move.
What is an earthquake?
Blocks on either side of the fault.
What are fault blocks?
A type of stress that stretches or pulls rocks apart.
What is tension?
This fault is caused by a divergent boundary.
What is a normal fault?
An opening at the top of volcanoes caused by eruptions.
What is a volcanic crater?
A large wave that can devastate cities.
What is a tsunami?
A type of stress the pushes rocks in parallel but opposite directions.
What is shear stress?
Mountains that form when tension makes the lithosphere split up into many different rocks.
What are fault block mountains?
This type of fault is caused by a convergent boundary.
What is a reverse fault?
An area where mantle plumes rise through the asthenosphere.
What is a hotspot?
The process where rocks return to the same shape after elastic deformation.
What is elastic rebound?
A process that causes land to rise and contributes to mountain building.
What is uplift?
A mountain that forms when melted rock erupts onto earth's surface.
What are volcanic mountains?
