Earthquakes
a break in the Earth's lithosphere where one rock moves towards, past, or away from one another
faults
scientist who studies earthquakes
seismologist
molten material below the surface
magma
where most volcanoes and earthquakes occur
plate boundaries
Oregon State University
Beavers
energy that travels as vibrations in or on Earth's surface
seismic waves
tool used to measure ground motion
seismometer
volcanoes that are not associated with plate boundaries
hot spot
a fluids resistance to flow
viscosity
Huskies
location above earth's surface directly above the earthquakes focus
epicenter
graphical illustration of a seismic wave
seismogram
3 main types of volcanoes
cinder, shield, and composite
2 of 4 possible effects- other things that could happen because a volcano erupts
lava flows, mud flows, ash fall, pyroclastic flow
University of North Carolina
Tar Heals
3 types of seismic waves
p- waves (primary), s-waves (secondary), and surface waves
How much more intense is a 7 earthquake than a 4 earthquake
1000 times more intense
(7-4 = 3 so, 10 x 10 x 10= 1000)
volcanic depression formed when a volcano's summit collapses or is blown away by explosive activity
caldera
mineral present in magma that determines its viscosity
silica
University of Alabama
Crimson Tide
area or location where sections of Earth's lithosphere move away, past, or towards each other
plate boundaries
3 scales used to measure an earthquake
Richter scale, moment magnitude scale, and mercalli scale
2 characteristics used to classify volcanoes
size and shape (maybe eruption type)
2 effects worldwide due to volcanic eruptions
increase in acid levels (in water), lower of global overall temperature
