Waves and Earthquakes
Terms in this set (20)
solids, liquids, gases that a wave can travel through
A wave in which the vibration of the medium is parallel to the direction the wave travels
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels
light waves, radio waves, X rays
no medium needed waves
stretched-out areas of a longitudinal wave
The shaking that results from the movement of rock beneath Earth's surface.
the maximum distance that the particles of a wave's medium vibrate from the rest position
distance between crest to crest on a transverse wave
P waves (Primary waves)
a type of seismic wave that is a compression wave and is parallel to the direction of the wave.
number of full wavelengths that pass a point in a given time interval
S waves (secondary waves)
Seismic waves that is a transverse wave and is perpendicular to the direction of the wave.
Point on Earth's surface directly above an earthquake's focus
seismic waves that travel along the Earth's surface
in tectonic plates, the site at which an oceanic plate is sliding under a continental plate.
measured in m/s
The theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle.
convection currents in the mantle
Most geologists think that the movement of Earth's plates is caused by
the record of an earthquake's seismic waves produced by a seismograph
