How do we know what's inside the earth
WebOne ingenious way scientists learn about Earth’s interior is by looking at how energy travels from the point of an earthquake. These are seismic waves (figure 1). Seismic waves travel outward in all directions from where the ground breaks at an earthquake. These waves are picked up by seismographs around the world. WebScientists know about the layers of the earth by sending sound waves through the earth. Because layers of different densities (see earlier question) will allow sound waves to …
