Seismic waves can help scientists to determine the structures of Earth’s interior because: A. Seismic waves travel through different materials at different speeds.
An epicenter can be defined as the point on the surface of planet Earth, which is typically perpendicular to the hypocenter (focus) and it indicates where the seismic waves from an earthquake are most intense.
Similarly, the location of an earthquake’s epicenter and seismic waves are used as an evidence to study Earth’s interior (inner core).
In conclusion, seismic waves can help scientists to determine the structures of Earth’s interior because they travel through different materials at different speeds.
