If such an earthquake was to strike L.A., the epicenter and the magnitude would be <u>Los Angeles</u><u> </u>and <u>7.8 </u><u>o</u>n the Richter scale respectively.
<h3>What is the epicenter and magnitude of an earthquake?</h3>
The epicenter of an earthquake is the place on the surface of the Earth where the earthquake is first detected which in this case is Los Angeles.
The magnitude is measured on the Richter Scale and in this case is 7.8 on that same scale which means it was quite a strong quake.

I’ve researched this for an hour and don’t see any of these answer choices , but my method is “ when in doubt C your way out “
D. He saw that the continent fits together like pieces of a jigsaw puzzle
as well, he had evidence from having similar rock formations from places that seemed to "connect", and he found fossils of the same dinosaur in different areas, that would have been impossible to go to because of the size and the inability to swim by the dinosaurs

Groundwater Storage, Porosity, and Specific Yield: Groundwater occupies the cracks and pore spaces between rocks and mineral grains below the land surface. In the saturated zone, essentially all of the pores are filled with water. If a volume of saturated aquifer material is completely dried, the water volume removed reflects the total porosity of the material, or the fraction of pore space within the total volume of solids plus open spaces. This number can be surprisingly large; some minerals and rock formations can have total porosities in excess of 50%. In the unsaturated, or vadose, zone there can be significant amounts of water present, but the voids are not completely filled (see appendix on saturated thickness).
However, some of the pore spaces may be too small or too poorly connected to permit the water they contain to flow out easily. The effective porosity can be thought of as the volume of pore space that will drain in a reasonable period of time under the influence of gravity. Effective porosity is always less than total porosity, sometimes (as in the case of clays) much less. "Good aquifers" tend to have values of effective porosity in the range of 10-30%, although examples of higher and lower values can be found. Figure 1 illustrates the relationship among the types of porosity and the volume of water in storage.
