Question 17 (1 point)
A seismic wave is a wave that propagates through a solid only
True
False

False! Seismic waves can travel through solids, liquids, and gases. There are two main types of seismic waves: primary § waves, which are compressional and can travel through all states of matter, and secondary (S) waves, which are shear waves and only move through solids. So, next time the earth shakes, remember that waves are on a multi-state mission!

When it comes to detecting these waves, seismographs are the rock stars of the show! These instruments measure ground motion and can help scientists analyze the intensity and duration of earthquakes, ultimately aiding in safety measures and preparedness strategies for communities in seismically active areas.
