Answer 1

The tool that has allowed scientists to learn about the characteristics of Earth's layers is the seismograph. Seismographs are instruments that measure and record the vibrations of the earth, such as those caused by earthquakes. By analyzing the way seismic waves travel through the Earth, scientists can infer the composition, state (solid or liquid), and other properties of its inner layers.
