Where would an earthquake's epicenter be in this diagram?
a. on earth's surface, directly above where the fault slippage begins
b. at the point on earth's surface where the fault line meets the surface
c. underground, at a point somewhere along the fault line
d. deep underground, below the point where the fault line meets the surface

The answer is A: On Earth's surface, directly above where the fault slippage begins

Hope this helps :)

Explanation:

Option (A)

Explanation:

The earthquake refers to the sudden shaking of the earth that occurs due to the release of energy during the seismic wave propagation through the interior of the earth. The point from which the earthquake arises is termed as the focus. The focus of an earthquake is also considered as the hypocenter. And the point that is directly above the focus (hypocenter) is known as the epicenter.

Similarly, this focus and the epicenter also occurs in a region where there is a presence of a fault, that results in earthquakes of various magnitudes. This means that the point that is directly above the start of the fault slippage is also known as the epicenter.

Hence, the correct answer is option (A).

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.
