A wave produced by an earthquake is traveling from west to east through rock. If the particles of the rock are vibrating in a north-south direction, what is the best classification of the wave? Group of answer choices

The best classification of wave mentioned in the question is longitudinal wave.

Explanation:

If the particle displaces parallel in the direction of wave propagation then it is simply called as the longitudinal wave. As mentioned in the question, the particle of rock is vibrating parallel to the wave propagation i. e north south direction not top down so it is shows the nature of longitudinal wave. In this wave system particle do not move top down, it only oscillates back forth.
