ATEP Â©2006-2008 UAF Geophysical Institute B-5 Seismic Waves Activity Procedure: 1. Explain students will study seismic waves. Seismic waves are waves that propagate through Earthâs interior. Much of what we know about Earth comes from study of seismic waves and how they travel through different materials. waves associated with earthquakes. Seismic waves can be classified into two major groups: body waves and surface waves. may be classified as compressional waves (P waves) or shear waves (S waves).
