Identify the TRUE statement. Question 19 options: The variety of different wave frequencies (the frequency content) of an earthq
uake remains the same with distance from the hypocenter. Low-frequency seismic waves cause more ground acceleration than do high-frequency waves. Low frequency waves lose energy more rapidly than high-frequency waves. In the Mexico City quake, high-frequency waves weakened with distance, but unconsolidated beds of the sedimentary basin there amplified low-frequency waves.
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.
The upper surface of this zone of saturation is called the water table. The saturated zone beneath the water table is called an aquifer, and aquifers are huge storehouses of water.
C) They believed Earth to be much younger than current estimates.
Explanation:
The proponents of the 18 and the 17th centuries believed that the earth was shaped by a strong and a violent forces such as the erosion that created the earth's geologic features and had a recent origin.
