Question

Which statements describe surface waves? Check all that apply. They arrive before S waves. They travel slower than P waves. They result in much ground motion. They are produced by P and S waves. They travel deep below Earth’s surface.

Answer 1

Answer:

They travel slower than P waves.

They result in much ground motion.

Explanation:

There are three types of seismic waves: P waves, S waves and Surface waves.

P wave are primary waves which require medium to travel. These are fastest waves. S waves are the secondary waves. These are transverse waves. S waves move slower than P waves. Both of these waves can travel through the inner layers of Earth.

Surface waves travel near the surface or above the surface of the Earth. These travel slower than S waves and P waves but have large amplitudes which could much ground motion and cause huge destruction.

Hence, the statements describe the surface waves:

They travel slower than P waves.

They result in much ground motion.
