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.

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 ...

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 ...

The stronger the wind, the longer it blows and the longer the fetch, or stretch of ocean over which it blows, the larger the waves (Figure 1). The world's greatest wave factories are in the zone ...
