Question

how do the behaviour of the seismic waves suggest layering of the interior of the earth?​

Answer 1

Answer:

The structure of the Earth

Because the speed of the seismic waves depends on density, we can use the travel-time of seismic waves to map change in density with depth, and show that the Earth is composed of several layers. ... Both P- and S-waves from earthquakes travel through the mantle, demonstrating that it is solid.
