Question
Seismic wavesMultiple choice question.are longitudinal waves or transverse waves.have amplitudes equal to half their wavelength.are always longitudinal compression waves.
Solution
Seismic waves are both longitudinal and transverse waves. They are generated by earthquakes, volcanic eruptions, magma movements, large landslides and large man-made explosions that give out low-frequency acoustic energy.
Longitudinal waves, also known as P-waves, cause particles in the ground to move back and forth in line with the direction the wave is moving.
Transverse waves, or S-waves, move the ground up and down and side-to-side in perpendicular motion to the direction the wave is moving.
Therefore, the correct answer to the multiple choice question is "Seismic waves are longitudinal waves or transverse waves."
