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.
Explanation:
Functional regions are made up of a central place and surrounding areas affected by it. Often, this is a metropolitan area that consists of a major city and lots of smaller towns or cities that surround it.
It would be a line going straight through the graph under the middle.
