Earthquake P-waves are most like
A)water waves because they have crests and troughs.
B)vibrations in a string because they vibrate perpendicularly to the direction of travel.
C)light waves because they are transverse.
D)sound waves because they are longitudinal.

Question

Quizplus · Accepted Answer

P-waves, or primary waves, are a type of seismic wave that move through the Earth during an earthquake, compressing and expanding the material they move through in the same direction that the wave travels, similar to sound waves. This makes them longitudinal waves, not transverse waves like light or water waves, and they do not vibrate perpendicularly like vibrations in a string.
