Seismic waves
Earthquake waves travel fastest in the interior of the Earth, as speed of waves increases as we go inside the Earth. The speed of a wave depends on the properties of the medium it travels in. The wave propagates faster in the denser and heavier core.
The waves of earthquakes help us determine information about the interior of the earth. The more geologists know about the interior of the earth, the better they can predict earthquakes and other changes in the formation of the Earth's crust.
Scientists use seismic waves to map Earth's interior by using seismographs that measure the times at which seismic waves arrive at different distances from an earthquake.
It is caused by rcording of earthquake waves
Earthquake waves
earthquake waves travel through the earths crust.
Only primary waves travel thought the earths interior because S waves cannot travel through the liquid portion of Earths interior and P waves can. Whoever you are, you were just schooled by an eighth grader =)

Earthquakes are when the seismic plates on the earths crust move after pressure from on another is exceeded, seismic waves are produced after an earthquake, and can turn into a tsunami.
Primary Waves or P waves come first and they are the quickest and travel through earth's interior. So if there is an earthquake in China the P wave will go through the earth and onto the other side in a couple of seconds and scientists know this because only a p wave can travel through liquid, solid, and gas and the interior of the earth is made up of semi-molten rock, molten rock and solid rock so we kind or know how the earth is inside.
