Which type of wave do you think were useful to seismologists in their study of theearths interior?

Seismologists use seismic waves, specifically body waves such as P-waves and S-waves, to study the Earth's interior. These waves travel through the Earth at different speeds and can provide information about the composition and structure of the Earth's layers. By analyzing the behavior of these waves, seismologists can gain insights into the properties of the Earth's interior.
