Step-by-step explanation:

Earthquake waves produces two very important waves that useful in studying the composition of the earth.

These waves are P and S-waves.

  • P-waves are primary longitudinal waves that propagates through any material medium.
  • S-waves are secondary transverse waves that can only pass through solids but not fluids.

Using these waves we can know the composition of the earth.
