D)fold to form synclines or anticlines.

Question

Quizplus · Accepted Answer

Seismic waves are produced when rocks rupture or break under stress, particularly along fault planes. This typically occurs when there is a sudden release of energy due to tectonic activity, such as earthquakes or volcanic eruptions. Compressional stress and plastic deformation may also contribute to the formation of seismic waves, but the primary cause is the breaking of rock. Fold formation is a type of deformation that does not necessarily involve breaking or rupture of rock and is therefore less likely to produce seismic waves.
