Question 5

The diagram shows a cutaway view of Earth in which the interior layers are visible. The paths of earthquake waves generated at point X are shown. A, B, C, and D are locations of seismic stations on Earth's surface, and point E is located in Earth's interior. 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?

Accepted Answer

The liquid outer core prevents S-waves from traveling to seismic stations C and D.

Answer

S-waves are much weaker than P-waves.

Answer

S-waves travel faster than P-waves.

Answer

The solid outer core prevents S-waves from traveling to seismic stations C and D.

Question 11

The diagrams below show demonstrations that represent the behavior of two seismic waves A (Push/Pull) and waves B (Perpendicular). Which statement concerning the demonstrated waves is correct?

Accepted Answer

Wave A represents a compressional wave, and wave B represents a shear wave.

Answer

Wave A represents a shear wave, and wave B represents a compressional wave.

Answer

Wave A represents compressional waves in the crust, and wave B represents compressional waves in the mantle.

Answer

Wave A represents shear waves in the crust, and wave B represents shear waves in the mantle.

Accepted Answer

silt and mud

Answer

hard igneous rock

Answer

sedimentary rock

Answer

coarse sediments

Question 14

Which statement best describes the relationship between the travel rates and travel times of earthquake P-waves and S-waves from the focus of an earthquake to a seismograph station?

Accepted Answer

Answer

P-waves travel at a slower rate and take less time.

Answer

S-waves travel at a slower rate and take less time.

Answer

S-waves travel at a faster rate and take less time.

Question 15

Question 18

When the seafloor moves as a result of an underwater earthquake and a large tsunami develops, what will most likely occur?

Accepted Answer

Severe destruction will occur in coastal areas.
