Different materials have different velocities of sound propagation.
Yes, P-waves (primary waves) can travel through the Earth's mantle. P-waves are a type of seismic wave that is capable of propagating through solid, liquid, and gaseous materials. They are the fastest seismic waves and can travel through the mantle, which is the layer between the Earth's crust and core.
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
The ozone layer.
Through condensation and evaporation.
Earth's outer core is liquid because S-waves are not transmitted through this layer
waves that travels only on the surface

The light takes approximately 8 minutes and 20 seconds to travel through layer 3.
Heat waves do not travel through the ozone layer. Some infrared radiation passes through it, but "far infrared" does not. Ozone is a greenhouse gas.
Seismic waves change speeds as they move through Earth's layers due to differences in the physical properties of the materials in each layer. Factors such as density, rigidity, and composition of the rock can affect how fast seismic waves travel through them. The waves can speed up, slow down, or change direction as they encounter different materials with varying properties.
S-waves are not transmitted through the outer core.
