I believe the answer would be D higher temperatures and more evaporation.
For much of the last quarter century, the leading theory of the driving force behind tectonic plate motions envisaged large scale convection currents in the upper mantle, which can be transmitted through the asthenosphere.
Answer:
C. Low-frequency seismic waves cause more ground acceleration than do high-frequency waves.
Explanation:
Low-frequency seismic waves covers more distance as compared to high-frequency waves because high frequency wave provide more energy to the medium while low frequency waves supply less energy to the medium so which makes the wave to go further. Lower frequency waves "penetrate" into a materials better, because energy particles having lower frequencies having less energy and they pass through the medium without interacting with the matter.
