Both P-waves and S-waves were received at seismic

stations A and B, but only P-waves were received at

seismic stations C and D. Which statement best

explains why this occurred?

• S-waves are much weaker than P-waves.

• S-waves travel faster than P-waves.

• The liquid outer core prevents S-waves from

  traveling to seismic stations C and D.

• The solid outer core prevents S-waves from

  traveling to seismic stations C and D.
