Front

Which behavior will NEVER occur with a P-wave as it travels through the Earth? Options: Refraction, Reflection, Absorption, Transmission

Back

Absorption

Front

Describe the speed of a P-wave and an S-wave as it travels through from the upper mantle to the lower mantle of the Earth?

Back

P and S waves' speeds increase.

Front

If a seismic wave's speed increases, then

Back

the wave is moving through more dense material
