Question

which statement describes surface waves?
○ they arrive before s waves.
○ they travel faster than p waves.
○ they are produced by p and s waves.
○ they travel deep below earths surface.

Explanation:

Surface waves are seismic waves that form when P (primary) and S (secondary) waves reach Earth's surface, making them the slowest and last to arrive. They travel along the surface, not deep underground, and are slower than both P and S waves.

Answer:

They are produced by P and S waves.
