Question

the diagram shows circles drawn by geologists trying to determine the location of an earthquakes epicenter. what does each star on the map represent? location of an epicenter location of a focus location of a seismograph location of a wave

Explanation:

To determine the epicenter of an earthquake, geologists use seismographs at different locations. The circles are drawn with radii equal to the distance from each seismograph to the epicenter. The stars represent the locations where seismographs are placed to record seismic waves. The epicenter is the intersection of these circles, the focus is the underground origin (not marked by stars), and waves aren't marked by stars. So the star represents the location of a seismograph.

Answer:

C. location of a seismograph
