Plate Tectonics
List the layers of the Earth from outermost to the innermost layer
lithosphere, asthenosphere, outer core, inner core
The place where the vibrations of an earthquake starts
focus
What type of volcano is this sloping volcano that produces slow oozing lava?
shield volcano
What type of fault would most commonly occur along a divergent boundary?
normal fault
The process by which new oceanic crust forms along a mid-ocean ridge and older crust moves away from the ridge
seafloor spreading
What type of plate boundaries most commonly form earthquakes?
transform boundaries
What type of volcano is this symmetrical volcano that produces very explosive eruptions?
stratovocano/composite volcano
What causes the Earth's tectonic plates to move?
Convection currents in Earth's mantle/athstenosphere
Denser plate sinks below the more buoyant plate
subduction
What is the name of the crack in the rock that often causes earthquakes
fault
What type of volcano is this volcano with one sloped and one steep side that is made through pyroclastic flows?
cinder cone volcano
What is formed by divergent boundaries on land?
rift valleys
What happens to plates at a divergent boundary?
They move apart
Three types of faults
strike slip, normal, reverse
What is this cauldron shaped mountain called? It was formed when a stratovolcano blew its top off during an eruption
Caldera
Name all of the earthquake waves in order that they appear during an earthquake
p waves, s waves, surface waves
What would form at a convergent boundary, where two continental plates are crashing into each other?
Mountains
What four natural disasters are triggered by earthquakes
landslides, liquefaction, tsunami, fire
why would high viscosity lava be easier to get away from than low viscosity lava after an eruption?
because it moves slower than low viscosity lava
Where is the largest volcano in our solar system?
Mars - olympus mons
