Answer:
There is no drawing here to label but I will go on to explain the the various types of waves with a diagram
Explanation:
P wave or the primary waves are the fastest waves in seismic waves. It is usually the first to arrive at seismic station. P waves are called compressional waves because they have ability to pull and push rocks as they pass through them. It is the first waves you notice during an earthquake.
S waves or the secondary waves is slower than the primary waves and moves through solid rocks and can not pass through liquid. It travels outside the earth core, and that has made seismologist to believe that the outer crust is liquid. It moves rocks up and down, side by side.
Surface Waves only travel through the earth crust. It is slower than P and S waves. It is the surface waves that cause physical destruction we notice during earthquake. The strength and extent of damage of surface waves is determined by the depth of the earthquake.
