Volcanology
A phaneritic texture indicates the magma cooled...
Slowly
We can interpret this property based on the presence of specific minerals sensitive to the temperature of formation.
Metamorphic grade
The second type of wave to arrive after an earthquake.
S-wave
An episode of mountain formation.
Orogeny
Carboniferous, or Pennsylvanian/Mississippian
A porphyritic texture tells us this about the history of the magma.
It cooled partly underground, and then erupted.
This type of metamorphism occurs close to igneous intrusions.
Contact metamorphism
The location of an earthquake underground.
Focus or hypocenter
A fault produced by shear stress.
Strike-slip fault
Renewable energy source with significant energy production where a large vertical drop exists.
Hydroelectric power
A stratovolcano with felsic magma is likely to erupt in this manner.
Explosively
This rock texture, seen in some metamorphic rocks, is a product of deviatoric stress.
Foliation
This setting produces the deepest possible earthquakes.
Subduction zones
A fault where the hanging wall drops relative to the footwall.
Normal fault
Anthracite
This tectonic setting is associated with melting because of water.
Subduction zone
This type of metamorphism is associated with continental collision settings.
Regional metamorphism
This is the only type of seismic wave that can travel through the outer core.
P-wave
This type of fold is shaped like the letter 'U.'
Syncline
Hydrocarbon 'seal' rocks have low...
Permeability
This process in the mantle produces the most abundant volcanism on Earth.
Decompression melting
A mica schist formed from this protolith.
Mudstone or shale.
This is a surface wave that moves side to side, like a snake.
Love wave
What two 'dip directions' are possible for a strike direction of 0º (that is, striking due north)?
East (90º) and West (270º)
Energy source whose only byproduct is water vapor
Nuclear, or hydrogen cells
