Got this from google, scientists count a species population by first knowing the population in a certain area or small geographical sample location then multiply the result by the total area.
In the mid-twentieth century and corroborated ever since, researchers dredging the seafloor could not find any materials older than 180 million years.

What do you understand by seafloor ?</h3>
The surface of an ocean or sea: seafloor According to this theory, the Earth's crust is divided into a number of enormous plates that together form the continents and ocean floors and are supported by a warm, plastic "mantle" beneath the surface. Mr. Walter Sullivan
Deposits of common minerals like copper, zinc, nickel, gold, silver, and phosphorus can be found on the seafloor. These deposits are nodules on silt from the abyssal plain that are typically 3 to 10 centimeters (1 to 4 inches) in diameter and appear as crusts on volcanic and other rocks.

Answer would be B. Earthquakes happen most of the time when a volcano is about to erupt.
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.
