- 9. Multiple Choice
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?
P and S waves' speeds increase.
P and S waves' speeds decrease.
P and S waves' speeds remain constant.
P and S waves' speeds stop.
- 10. Multiple Choice
If a seismic wave's speed increases, then
the wave is moving from a solid to a liquid
the wave is moving through more dense material
the wave is moving through less dense material
the wave is moving through material that has the same density
