Surface waves usually have larger amplitude than the other waves and cause the most damage. A P wave is a longitudinal wave and travels the fastest. It can travel through solids and liquids. An S ...

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 ...

Tell students that the released energy can travel through the Earth's interior and along its surface ... wave passes, the material first compresses and then expands. P-waves (P stands for primary ...

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 ...
