What causes the shadow zone for no S-wave arrivals beyond epicentral angles of 100°?
A) The Earth is hollow.
B) The liquid outer core will not pass shear waves, so any down-going shear wave energy is converted to additional "late" P waves at the mantle-core boundary.
C) All shear waves are converted to surface waves at the mantle-core boundary.
D) All seismographs are located on the near side of the earth.
