Earthquakes #2
Vocabulary
100
Types of boundaries on Earth's crust where mountains form.
What are convergent and divergent boundaries?
100
Molten rock that spews out of a volcano.
What is lava?
100
Plates break and slide, creating a rapid release of energy that is sent out as seismic waves.
What is the cause of an earthquake?
100
Earthquake waves
What are seismic waves?
100
Molten rock beneath the Earth's surface.
What is magma?
200
Mountains formed by folding of rock layers caused by compression forces.
What are folded mountains?
200
Gentle-erupting volcano, usually formed in the ocean.
What is a shield volcano?
200
The type of boundary where earthquakes usually occur.
What is a transform boundary?
200
It identifies the intensity of an earthquake by measuring the height of the amplitude of the largest wave.
What is the Richter Scale?
200
A "water volcano" below the surface of Earth that shoots out hot water and steam.
What is a geyser?
300
Mountains that form due to the breaking and sliding of slabs of rock along faults.
What is fault block mountain?
300
Magma punches through the crust within a plate. Think Hawaii!
What is a hot spot?
300
The most damaging type of seismic wave.
What are surface waves?
300
This is the point on the surface directly above the focus.
What is the epicenter?
300
A build up of energy that produces a pulling force on tectonic plates. This usually occurs along transform boundaries.
What is tension or stress?
400
The Appalachian Mountains.
What is an example of folded mountains?
400
The hot cloud of gas and ashes that flow out of composite volcanoes. This was the cause of the death's of the people of Pompeii and Herculaneum.
What is pyroclastic flow?
400
Fractures or breaks in the tectonic plates where earthquakes occur.
What are faults?
400
This scale measures the intensity of an earthquake by a rating of 1-12 of the total destruction that was caused.
What is the Mercalli Scale?
400
The tendency for the deformed rock to spring back along a fault after an earthquake.
What is elastic rebound?
500
Hypothermia, disorientation, blindness, lack of oxygen, avalanches, and death.
What are some hazards of climbing Mount Everest?
500
The lava's resistance to flow.
What is viscosity?
500
Famous fault line in California.
What is the San Andreas fault?
500
The instrument used to measure earthquakes.
What is a seismograph?
500
Area beneath Earth's surface where rock that is under stress begins to break, triggering an Earthquake.
What is the focus?
