An earthquake happens somewhere in the United States, and three different seismic stations record the earthquake: Station 1 is in Phoenix, Arizona;
Station 2 is in Denver, Colorado;
Station 3 is in Sacramento, California .

The geologists at each station look at their seismograms and determine the distance to the earthquake from each of their stations. It is found that the earthquake is 380 miles from Station 1, 280 miles from Station 2, and 880 miles from Station 3. Where is the epicenter of the earthquake

If you could drill a hole straight to the center of the earth, and keep track of what the hole is going through, youwould find: a) you would go through one sort of material, and then a different, denser material, and then a still-different, still-denser material, because the planet is made of concentric layers, sort of like an onion.b) you would go through one sort of material all the way to the center, because the planet is all mixed up.c) if your hole started at the north pole, you would go through different layers of different materials, but ifyour hole started at the equator, you would go through one sort of material all the way to the center.d) if your hole started at the equator, you would go through different layers of different materials, but if yourhole started at the north pole, you would go through one sort of material all the way to the center.e) you would strike diet pepsi when you got to the center.
