Earthquakes
When an earthquake occurs in the ocean, water displaced by the earthquake can form this.
What is a tsunami?
The type of fault caused by shearing.
What is a transform fault?
A volcano that is not active, but may become active in the future.
What is a dormant volcano?
This is a major volcanic belt that rims the Pacific Ocean.
What is the Ring of Fire?
The type of eruption that has magma easing slowly with gases bubbling out gently.
What is a quiet eruption?
Earthquakes typically result at this kind of tectonic plate boundary.
What is convergent?
The type of stress associated with the creation of mid-ocean ridges.
What is tension?
The interior area found at the bottom of the volcano.
What is the magma chamber?
Bowl-shaped area around a volcano's central vent.
Normal faults result in what typical landform.
The seismic wave that arrives at the seismometer first.
What are P waves or primary waves?
When a fault is formed, this type of strain is illustrated.
What is plastic strain?
fast moving, hot lava
Pahoehoe
This type of volcano results from ash, cinders, and bombs building up in a steep pile around the vent.
What is a cinder cone volcano?
Water heated by magma can provides this kind of energy source.
What is geothermal?
The point below the Earth's surface which breaks and triggers the earthquake.
What is the focus?
The type of stress that produces a reverse fault.
What is compression?
The three stages of volcanic activity.
What are active, dormant, and extinct?
Magma that hardens in the volcano's pipe becomes this type of landform.
What is a volcanic neck?
A fluid's resistance to flow.
What is viscosity?
The type of seismic wave that travel in an up and down motion.
What are S waves or secondary waves?
A change in rock caused by stress but is not permanent.
What is elastic strain?
Magma becomes lava one it reaches this part of a volcano.
What is the crater or vent?
Magma that is solidified under the surface of earth.
What is a batholith?
The hanging wall moves down the foot wall causes this type of plate boundary.
What is divergent?
