100
crust, mantle, and core
What are the compositional layers of Earth?
100

thin, more dense crust

What is oceanic crust?

100
bending of rock layers due to stress
What is folding?
100
melted rock found in underground chambers
What is magma?
100
the Pacific plate boundaries
What is where most earthquakes occur?
200
lithosphere, asthenosphere, mesosphere, inner core, and outer core
What are Earth's physical layers?
200
thick, less dense crust
What is continental crust?
200
normal fault
What is when the hanging wall falls due to tension?
200
volcanoes formed primarily by pyroclastic materials
What is cinder cone?
200
building materials best able to withstand an earthquake
What are steel and wood?
300
convection currents
What is the motion within the asthenosphere that moves the plates?
300
mid-ocean ridge
What is formed at a divergent plate boundary?
300
Folded mountains are formed as a result of compressional stress.
What is when two continents collide?
300
volcanic feature that is a relatively small depression around a volcano's vent
What is a crater?
300
body waves travel outward from the focus and surface waves travel only on the surface
What is the difference between body and surface waves?
400
combination of crust and upper most mantle
What is the lithosphere?
400
plates come together
What is a convergent plate boundary?
400
volcanic mountains and trenches form at these zones (located at convergent boundaries)
What is the process of subduction?
400
where hot plumes of mantle rise through convection
What is a hot spot?
400
rocks along an underground fault move suddenly and release energy
What is the cause of an earthquake?
500
mesosphere
What is the lowest layer of the mantle?
500
plates slide past each other
What is a transform boundary?
500
the process by which rocks change shape under stress
What is deformation?
500
an opening at the surface of Earth through which volcanic material passes
What is a vent?
500
Rock deforms, and then returns to its undeformed shape, releasing energy.
What is earthquake formation?
