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.

These waves are higher frequency than surface waves. P waves are also known as compressional waves, because they push and pull. Particles subjected to a P wave move in the same direction that the wave ...

When a quake or impact occurs, it generates P-waves (primary waves) and S-waves (secondary waves) that travel through different layers at varying speeds. By analyzing how these waves reflect ...

using both P waves and S waves to explain how scientists calculate the epicentre of an earthquake. Use a glass bowl filled with tomato soup and cut outs of the continents to show how they would ...

This rare wave pattern occurs when two swells coming from different directions meet and form squares on top of the water, often resembling a checkerboard or grid. It's called a cross sea because ...

It’s easy to hear a note from [ELP Lucky Man] and when listening carefully one can start to equate sine wave distortions with “spray” or the extra harmonics that give some depth to a note ...
