Answer:
The correct options are;
A. The longer the S- and P-waves travel, the farther apart their wave fronts are in kilometers.
D. The larger the S–P value is, the farther the seismometer is located from the epicenter.
E. The farther the epicenter is, the greater the time difference in the arrival of the P- and S-waves at a seismometer.
Explanation:
Analyzing each of the statements, we have;
A. A P wave travels much faster than an S wave and a S wave can travel only through solid rock.
Therefore, A. the longer the S and P waves travel, the farther apart their wave fronts are in kilometers is correct
B. A P wave travels much faster than an S wave therefore, B is not correct as the epicenter and seismometer are two points separated by a distance which if the distance increases, the time interval between the arrival of the P and S wave increases
C. For similar reason, C is not correct
D. As the P wave travels much faster than an S wave, D is correct
E. Similarly, E. is correct, due to the difference in speed of the S and P waves
