In 2021 and 2022, NASA’s InSight lander picked up the tremors coming from the depths of Mars. These Marsquakes were quickly linked with orbital images revealing fresh craters. This was no coincidence: ...

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.

Primary waves, or P waves, are the first waves produced by a quake, and move the ground in the same direction that the wave is moving. Shear waves, or S waves, are slower than P waves and move the ...

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 ...

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 ...
