Answer:The order of seismic wave speeds from fastest to slowest is:
Primary waves (P-waves)
Secondary waves (S-waves)
Surface waves
P-waves are the fastest type of seismic wave, with speeds of up to 6-7 km/s in the Earth's crust, while S-waves are slower, with speeds of up to 3-4 km/s in the Earth's crust. Surface waves are the slowest type of seismic wave, with speeds of up to 0.5-1 km/s in the Earth's crust.
