The diagrams show what happens when P waves and S waves pass through the Earth. S waves do not pass through the Earth's core S waves cannot pass through the liquid outer core, but P waves can.

Earth’s innermost layer is a hot ... Earthquakes generate two types of waves. Primary waves, or P waves, are the first waves ...

P-waves (P stands for primary) are compressional earthquake waves that pass through the interior of the Earth. P-waves change the volume of the material through which they propagate. Note ...

Traveling through the interior of the Earth, body waves arrive before the surface waves emitted by an earthquake. These waves are higher frequency than surface waves. P waves are also known as ...

The Earth has a layered structure ... There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their relative speed is faster than ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...
