The seismograms were recorded at earthquake recording stations A, B, and C. The letters P and S on each seismogram indicate the arrival times of the compressional (primary) and shear (secondary) seismic waves. A fourth station recorded the same earthquake. The P-wave arrived, but the S-wave did not arrive. The best explanation for the absence of the S-wave is that the 1) S-wave traveled only on the Earth's surface and did not penetrate the Earth's interior 2) S-wave stopped when it reached a solid part of the Earth's interior 3) S-wave stopped when it reached a liquid part of the Earth's interior 4) S-wave was never transmitted by the earthquake

Which statement best explains why station X received only P-waves? 1) A liquid zone within the Earth stops S-waves. 2) P-waves and S-waves are refracted by the Earth's core. 3) Station X is too far from the focus for S-waves to reach. 4) S-waves traveled too slowly for seismographs to detect them.

The primary cause of convection currents in the Earth's mantle is believed to be the 1) rotation of the Earth 2) subsidence of the crust 3) occurrence of earthquakes 4) differences in densities of earth materials

Igneous rock along oceanic ridges is younger than the igneous rock farther from the ridges. This evidence supports the theory that 1) the ocean floor is stable 2) volcanoes one existed on both sides of the oceanic ridges 3) the ocean floor is spreading 4) oceanic ridges are areas of subsidence
