which statement describes how geologists use data from seismographs to learn about earthquakes? they often compare information from all over the world. they map the location of an earthquakes focus. they use one reading to determine the location of an epicenter. they measure the difference between the arrival times of surface waves.

which statement describes how geologists use data from seismographs to learn about earthquakes? they often compare information from all over the world. they map the location of an earthquakes focus. they use one reading to determine the location of an epicenter. they measure the difference between the arrival times of surface waves.

Answer

Brief Explanations:

Geologists use data from multiple seismographs around the world to map the location of an earthquake's focus. One seismograph reading is not enough to determine the epicenter. Measuring surface - wave arrival times is not the main way to learn about earthquakes from seismographs. Comparing global information helps in understanding seismic patterns and locating earthquake foci.

Answer:

They map the location of an earthquake's focus.
