The seismic waves with the largest amplitudes are called?
Ground motion consists of two things. What are the two things?
A magnitude 5 earthquake realeases _ times as much energy as a magnitude 3 earthquake?
Unconsolidated soil undergoes (MORE OR LESS) ground shaking than solid (consolidated) bedrock.

S waves have the larger amplitude.
Ground motions consists of compression and shear forces, or longitudinal and transverse (I think that's what you're asking)
I don't want to really answer this as I am sure you were taught something much simpler than the real answer. The energy released is logarithmic but the base is 32, not 10, so a two unit increase is actually about 900 times more energy.
Unconsolidated soils are subject to something called liquefaction, which can be more destructive.

Shear ( S ) wave and Raleigh ( R ) wave will have largest amplitudes.
Vertical & harizondal movements.
1024 times more energy and 100 times more shaking.
Building in solid rock is safer than that on loose soil because of the amplification factor and liquifications.
