Determine the difference in time between the arrival of the P waves and arrival of the S waves from the earthquake.
Use a travel-time graph to determine how far each seismograph station is from the epicenter.
Use the technique of triangulation to pinpoint the location of the quake.
Below is data from one of the stations to pick up the waves. It is located in Helena, Montana. The first set of squiggly lines represent the P wave while the 2nd set of squiggly lines represent the S wave (which moves slower). What is the time difference between the arrival of the P wave and the S wave? (remember reference the difference from where each wave BEGINS)

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.
