Random Tidbits
100
These waves originate where waves first move along the fault at the location inside earth called the focus.
What are seismic waves?
100
Is a vent in earths crust through which melted or molten rock flows.
What is a volcano?
100
Are the vibrations in the ground that result from movement along breaks in earths lithosphere.
What is a earthquake?
100
Volcanoes that are common along divergent plate boundaries and oceanic hot spots.
What is a shield volcano?
200
Cause particles in the ground to move in a push-pull motion similar to a coiled spring
What are primary waves?
200
Molten rock below the earth's surface.
What is magma?
200
Is a break in Earth's lithosphere where one block of rock moves toward, away, from, or past another.
What is a fault?
200
Tiny particles of pulverized volcanic rock and glass.
What is volcanic ash?
300
Cause particles in the ground to move up and down in a rolling motion.
What are surface waves?
300
Molten rock that erupts onto earth's surface.
What is lava?
300
Is the location on Earth's surface directly above the earthquake's focus
What is an epicenter?
300
A graphical illustration of seismic waves.
What is a seismogram?
400
They cause particles to move up and down at right angles relative to the direction the wave travels.
What are secondary waves?
400
Volcanoes that are not associated with plate boundaries.
What is a hot spot?
400
Scientists that study earthquakes.
What is a seismologist?
400
Are large steep-sided volcanoes that result from explosive eruptions of andesitic and rhyolitic lava and ash along convergent plate boundaries.
What is composite volcanoes?
500
Are small steep sided volcanoes that erupt gas-rich, basalt, and lava.
What is a cinder cone volcano?
500
Measures and records ground motion and can be used to determine the distance seismic waves travel.

500
A liquids resistance to flow.
