Show:
earthquakes
faults and boundaries
volcanos
volcano eruptions
scales and waves
100
vibrations caused by the rupture and sudden movement of rocks along a break or a crack in Earth's crust
What is earthquakes
100
forces pull two blocks of rock apart. the block of rock above the fault moves relative to the block of rock below the fault
What is Normal Fault
100
magma that erupts onto earths surface
What is lava
100
positive results of volcanic eruptions
What is soil and rock are enriched with valuable nutrients
100
measures magnitude
What is Ritcher MAgnitude scale
200
the location on Earth's surface directly above an earthquake's surface
What is the epicenter
200
two blocks of rock slide horizontally past each other in opposite directions
What is Strike-slip
200
a vent in Earth's crust though which molten rock flows
What is volcano
200
what does a high amount of silica do to lava
What is higher viscosity which makes thicker lava
300
energy that travels as vibrations on and in Earth
What is seismic waves
300
forces push two blocks of rock together. the block of rock above the fault moves up relative to the block of rock below the fault
What is Reverse fault
300
molten rock stored beneath Earths surface
What is magma
300
how does the amount of silica effect the flow of the magma
What is the more silica the higher the viscosity, the thicker the magma and slower the flow
400
a location inside Earth where seismic waves originate and rocks first move along a fault and from which seismic waves originate
What is focus
400
the boundary where the plates come together(reverse fault)
What is convergent boundary
400
tiny particles of pulverized volcanic rock and glass
What is volcanic ash
400
basaltic magma produces nonexplosive eruptions such as those at...(the most active volcano)
What is Kilauea
500
a crack or a fracture in Earth's lithosphere along which one block of rock moves toward, away from, or past another
What is fault
500
the boundary where the two rocks slide past eachother horizontally(Strike-slip)
What is transform boundary
500
a location where volcanoes form far from plate boundaries
What is hot spot
500
what type of flow moves at speeds of more than 100 km/hr and have temperatures of 2,000 degrees celcius
What is pyroclastic flows
