Linked from

The 20 pages that link to P waves, each with the reason it gives.

• Seismic waveBroader topic: Its early arrival and ability to cross liquid layers distinguish it from other seismic waves.

• SeismologyBroader topic: First arrival at a seismometer; its travel time fixes the earthquake's distance.

• Seismic tomographyBroader topic: Its travel times provide a major source of constraints on interior speeds.

• Seismic reflectionBroader topic: P-waves commonly provide the principal arrivals in reflection surveys.

• Seismic anisotropyBroader topic: Its direction-dependent speed can provide evidence for anisotropic elastic structure.

• Mohorovičić discontinuityBroader topic: Its velocity typically rises across the crust–mantle boundary.

• Seismic refractionBroader topic: Its speed commonly increases with depth, making it the principal refraction-wave type.

• Longitudinal waveBroader topic: P-waves are longitudinal waves that travel through Earth’s interior.

• Seismic velocityBroader topic: Its speed is governed by bulk and shear moduli together with density.

• SeismogramBroader topic: It is commonly the first earthquake wave visible on a seismogram.

• Birch's lawBroader topic: Birch's law is commonly applied to the velocity of compressional waves in minerals.
