Faults
What is a fault?
what is a break in Earth's lithosphere where one block of rock moves toward, away from, or past another?
Primary waves are often called what?
What are P-Waves?
What is a cinder cone volcano?
What are small, steep-sided volcanoes; made from moderately explosive eruptions of gas-rich, basaltic lavas; found along any plate boundary and oceanic hot spots
the spread of lava as it pours out of a vent; relatively slow moving
What is a normal fault?
What is when two blocks pull away from each other
What is the motion a P-Wave sends often compared to?
What is a slinky?
What is a shield volcano?
large, shield-shaped volcano with gentle slopes made from basaltic lavas; common along divergent plate boundaries and oceanic hot spots
What is viscosity?
a liquid's resistance to flow
A reverse fault is found where?
What do surface waves do?
They cause particles to move up and down in a rolling motion.
What is a composite volcano?
large, steep-sided volcanoes that result from explosive eruptions of andesitic and rhyolitic lava and ash; common along convergent plate boundaries
What is volcanic ash?
tiny particles of pulverized volcanic rock and glass
A normal fault is found at which plate boundar?
What is a divergent plate boundary?
What do P-waves do?
also called P-waves, cause particles in the ground to move in a push-pull motion similar to a coiled spring (or a slinky!); and travel through solids and liquids; are the faster and the first to be felt
What is a supervolcano?
volcanoes that have very large and explosive eruptions
What is magma?
Molten rock beneath Earth's surface
Where are strike-slip faults found?
What is a transform plate boundary?
What do secondary waves do?
also called S-waves, they cause particles to move up and down at right angles relative to the direction the wave travels; only travel through solids; are slower than P-waves but faster than surface waves
What is a caldera?
large volcanic depression formed when a volcano's summit collapses or is blown away by explosive activity
What is lava?
Molten rock above Earth's surface
