why p waves travel faster?

why p waves travel faster?
P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them. P-waves are compression waves that apply a force in the direction of propagation. ... The energy is thus less easily transmitted through the medium, and S-waves are slower.

Do P waves travel faster through denser material?
The first is that P waves travel faster than S waves. This is the reason they are referred to as primary waves, as they are the first seismic waves to arrive at a seismic station. ... More importantly for our purposes, P waves travel faster through denser rock, slower through less dense rock.

How do P waves travel?
P waves travel through rock the same way that sound waves do through air. That is, they move as pressure waves. When a pressure wave passes a certain point, the material it is passing through moves forward, then back, along the same path that the wave is traveling. P waves can travel through solids, liquids and gases. Jan 12, 2018

How fast do P waves travel?
Typical values for P wave velocity in earthquakes are in the range 5 to 8 km/s. The precise speed varies according to the region of the Earth's interior, from less than 6 km/s in the Earth's crust to 13.5 km/s in the lower mantle, and 11 km/s through the inner core.

Where do P waves travel the fastest?
Because the earth's mantle becomes more rigid and compressible as the depth below the asthenosphere increases, P - waves travel faster as they go deeper in the mantle. The density of the mantle also increases with depth below the asthenosphere. The higher density reduces the speed of seismic waves.
