WebFeb 13, 2015 · In order to understand layers in the Earth scientists use body waves. They are Primary (P) and Secondary (S) waves. After an earthquake seismic stations record P and S waves respectively. P waves are faster than S waves (Fig 1). Since P waves are faster than S waves there is a lag between two of them. WebScientists know about the layers of the earth by sending sound waves through the earth. Because layers of different densities (see earlier question) will allow sound waves to …

WebThe interior of the earth is not simply layered. Some of the layers, particularly the crust and lithosphere, are highly variable in thickness. The boundaries between layers are rough and irregular. Some layers penetrate other layers at certain places. WebEach of those layers (lithosphere, asthenosphere, mesospheric mantle, outer core, inner core) contain different mechanical (and chemical) properties.
