With references .

Answer 1

The structure of Earth's deep interior cannot be studied directly. But geologists use seismic (earthquake) waves to determine the depths ... Seismic and the Earth. they came. Geologists use these records to establish the structure of Earth's interior. The two principal types of seismic waves are P-waves (pressure; goes through liquid and solid) and S-waves (shear or secondary; goes only through solid - not through liquid). A seismologist is a scientist who studies earthquakes and seismic waves. ... Traveling through the interior of the earth, body waves arrive before the surface waves emitted by an earthquake. These waves are of a higher frequency than surface waves. P Waves. The first kind of body wave is the P wave or primary wave.
