* P waves (Primary waves) are compressional waves that travel through solids, liquids, and gases. They are the fastest type of seismic wave and are the first to arrive at a seismograph after an earthquake.

* Surface waves are slower waves that travel along the Earth's surface. They are generated by the interaction of P waves and S waves with the surface. There are two main types of surface waves:

* Love waves: These waves are horizontal shear waves that travel along the surface.

* Rayleigh waves: These waves are a combination of compressional and shear motions that travel in a rolling motion.

Speed Comparison:

* P waves: Typically travel at speeds of 4-8 km/s (2.5-5 mi/s).

* Surface waves: Typically travel at speeds of 2-4 km/s (1.2-2.5 mi/s).

Therefore, P waves move faster than surface waves.
