no! ITS BECAUSE s WAVES GO ONLY THROUGH SOLIDS AND P WAWES GO THROUGH LIQUID GASSES AND SOLIDS AND WE CAN TELL LIKE HOW THE CORE IS A LIQUID
s waves cannot travel through liquids. p waves can. so after an earthquake happens the other side of the earht only receives p waves therefor the earhts interior is made up of liquids

The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.

it tells us that the earths interior (core) is a liquid
that the earth is going to end in 2 days

Seismic waves are the waves that rapidly move through the earth's crust causing a shift in techtonic plates. These waves tell us how strong an earthquake was.

A sizemograph is used to mesure the sizemic waves under the earths surface
No. Fossils tell us about what was living at or near the earths surface in the past, they do not tell us about the Earth's interior. When studying the Earth's interior, geologists look at micro gravity variations (which tell us about density differences in deep rocks), magnetic variations (which tell us a bit about the deep rocks composition) and most importantly seismic records (which tell us about the physical properties of the deep rocks). We also look for deep rocks that have been brought to the surface during the collision of continents (the roots of mountains) and volcanic events (such as diamond pipes).
scientists can tell what the interior looks like by the different type of waves there is. scientists know that P (primary) waves can travel through any substance, and that S (secondary) waves can travel only through solids and stop at liquids when P waves slow down at liquids. when they monitor the p and s waves they realize that after a certain distance (2932 km) the s waves stop and p waves slow down. thus meaning it is in the liquefied outer core. but after a certain amount of time the p waves speed up again. this means it has left the outer core into the solid inner core.
