Packet 10: Bonus 14
This adjective describes two types of waves whose velocity is related to density and little g by the Adams-Williamson equation. For 10 points each:
[10e] P-waves and s-waves are examples of disturbances described by what adjective that cause vibrations in the Earth and may arise from earthquakes?
ANSWER: seismic [accept seismic waves; accept seismic wave velocity]
[10m] Due to a decrease in density, seismic wave velocity increases after passing this feature. This boundary marks the transition between the Earth’s mantle and crust.
ANSWER: Mohorovičić discontinuity
[10h] The velocity of p-waves is proportional to the square root of this quantity, which is the ratio of volumetric stress to volumetric strain.
ANSWER: bulk modulus [prompt on B or K; prompt on incompressibility]
