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.
