What can P waves and S waves travel through?
P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. A P wave is a sound wave traveling through rock. These waves can travel through solids, liquids, and gases. P waves can travel through the liquid outer core.
Why can P waves travel through any substance?
P-waves pass through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km. S-waves passing from the mantle to the core are absorbed because shear waves cannot be transmitted through liquids. This is evidence that the outer core does not behave like a solid substance.
Can P waves travel through gas?
P waves are compressional waves. Therefore, they too can travel through solids, liquids and gases.
How does P wave move?
How do P and S-waves move? P-waves are the fastest waves created by an earthquake. They travel through the Earth’s interior and can pass through both solid and molten rock. They shake the ground back and forth – like a Slinky – in their travel direction, but do little damage as they only move buildings up and down.
