Can P waves pass through liquids?
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.
What substances can P waves travel through?
P-waves travel through liquids and gases as well as through solids. Because the earth’s mantle becomes more rigid and compressible as the depth below the asthenosphere increases, P-waves travel faster as they go deeper in the mantle.
Can P waves travel through solids liquids and gases?
P waves are compressional waves. Therefore, they too can travel through solids, liquids and gases. Shear waves can travel only through solids. Thus, S waves (which are a type of shear wave)will travel through solids and but will be absorbed by liquids and gases.
Can secondary waves travel through liquids?
Secondary waves rock small buildings back and forth as they pass. Secondary waves can travel through rock, but unlike primary waves they cannot travel through liquids or gases. When scientists learned that secondary waves cannot pass through Earth’s outer core, they realized that the outer core is not solid.
