Data about P waves and S waves traveling through the mantle has been used to map out convection in the mantle. Waves tell researchers whether the mantle is more or less dense than average, hotter or cooler than average and whether it is rising and falling. The Earth releases internal heat by convecting.hanks to earthquakes, the seimic waves they give off and the instruments used to gather data abouth such events, we now know the chemical composition, temperature, density and depth of the layer's of the Earth's inside. The earth is divided in to four layers: CRUST, MANTLE, OUTER CORE and INNER CORE.
