structure of Earth?

Answer 1

3. What is the relationship between S- and P-waves?

The relationship between S and P waves is that they both arrive before surface waves, but P waves arrive before S waves.

4. How did the study of earthquake waves lead to a greater understanding of the interior structure of Earth?

The study of seismic waves led to a better understanding of the interior of Earth since these waves travel at different speeds in different materials. This study has helped scientists get a better understanding of the inner components of Earth.

Answer 2

3. p waves travel faster than s waves, and are the first waves recorded by a seismograph in the event of a disturbance. p waves travel at speeds between 1 and 14 km per second, while s waves travel significantly slower, between 1 and 8 km per second.
4. seismic waves, the waves of energy that travel through earth as a result of an earthquake can tell us a lot about the internal structure of the earth because the waves travel at different speeds in different materials. there are two types of waves that travel through the earth: p waves and s waves.
