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.
The correct answer is: dependent variable.
