when forces pull tow blocks of rock apart. The blocks of rock above the fault moves down relative to the block of rock below the fault.
What is a normal fault
100
a vent in Earth's crust through which molten rock flows
What is a volcano
100
a small, steep-sided volcano that erupts gas-rich, basaltic lave
What is cinder cone
100
what does the Richter Magnitude Scale measure
What is magnitude
200
energy that travels as vibrations on and in Earth
What is a seismic wave
200
two blocks of rock slid horizontally in opposite directions
located t transform plat oundaries
What is a trike sip
200
molten rock stored beneath Earth's surface
What is magma
200
a large volcano with gentle slopes off basaltic lavas, common along divergent pate boundaries and oceanic hotspots
What is shield volcano
200
what are the positive results of volcanic eruptions
What is rock and enriched soil
300
a crack or a fracture in Earth's lithosphere along which one block or rock moves toward, away from, or past another
What is a fault
300
when forces push two block of rock together. The block of rock above the fault moves up relative to the block of rock below the fault
What is a reverse fault
300
magma the erupts onto Earth's surface
What is lava
300
a large, steep-sided volcano that results from explosive eruptions of and andesitic and rhyolitie lavas along convergent plate boundaries
What is composite volcano
300
which volcano in the world is the most active
What is Kilauea
400
a type of seismic wave which causes particles in the group to move in a push-pull motion similar to a coiled spring. There waves arrive first to a seismometer
What is Primary wave
400
this fault occurs at a transform plate boundary
What is a strike slip fault
400
a location where volcanoes form far from plate boundaries
What is a hot spot
400
basaltic magma produces nonexplosive eruptions such as those at...
What is kilaues
400
What type of flow moves at speeds of more than 100 kn/hr and have temperatures of 2,000 degrees celsius
What is Pyroclastic flows
500
A type of a seismic wave that causes particles in the ground to move up and down in a rolling motion
What is surface wave
500
this fault occurs at a convergent plate boundary
What is reverse
500
tiny particles of pulverized volcanic rock and glass
What is volcanic ash
500
1. forms at convergent boundaries where one plate is forced under another
2. produces explosive eruptions
3. is thick and traps gas, causing pressure to build
What is examples of silica-rich magma
500
This scale evaluates the damage that results from shaking
