Secondary (S)seismic waves in Earth have the following characteristics:
A) vibrations perpendicular to the direction of travel of the waves;cannot traverse liquids.
B) vibrations perpendicular to the direction of travel;only travel along the surface of Earth.
C) vibrations along the direction of travel of the waves;cannot traverse liquids.
D) vibrations perpendicular to the direction of travel of the waves;can traverse liquids.

Question

Quizplus · Accepted Answer

Secondary (S) seismic waves, also known as shear waves, exhibit vibrations that are perpendicular to the direction of wave travel. Unlike primary (P) waves, S waves cannot travel through liquids, which is a key characteristic used in studying the Earth's internal structure, including the liquid outer core.
