Seismic waves travels faster through solid rock than water because their speed depends on the density and composition of material that they pass through.Solid rock is denser than water, hence the energy from seismic waves transfer faster through solid rock than in water.
Seismograms give information about the path of seismic waves and the speed of seismic waves. The speed of seismic waves depends on the density of the material the seismic wave is traveling in. We know, for example, that the core of Earth is liquid, because S waves do not travel through the center of Earth.
Seismic waves that can pass through the centre of the Earth must be capable of travelling through liquids (as the outer core is molten). As such we know that these waves are longitudinal or compression waves.
Seismic wave velocity is mostly dependent on the material they travel through (things like magnitude do not affect wave velocity). As the earth is relatively uniform, there is virtually no deviation in earthquake 'speed'. (Wave velocity will differ depending on phase, depth, etc. - but that's different.)
The speed of seismic waves is influenced by the density and elasticity of the material they travel through. Generally, denser materials can transmit seismic waves faster if they also possess high elasticity. This is because the stiffness of the material, which is a measure of its ability to resist deformation, combined with its density, determines how quickly the energy can propagate through it. Thus, while density alone affects wave speed, it must be considered alongside other properties like elasticity to fully understand its impact.
The speed of seismic waves are affected by the type of material that the waves are traveling through. in other words (as an example): some type of waves can travel through rocks but not through liquids.
Primary waves (P-waves) move through Earth at the fastest speed among seismic waves. They are able to travel through both solids and liquids, making them the first waves to be detected after an earthquake.
The velocity of seismic waves is controlled by the density and elastic properties of the material through which they travel. Solids tend to have larger elastic modulii than fluids. As the speed of a seismic wave increases as the elastic modulii increase, this means that they tend to travel faster through solids.
"True, the Seismic Waves change speed and direction when they encounter different materials."
The seismic wave that travels fast and increases its speed with depth is called a primary or P-wave. P-waves are compressional waves that can travel through solids, liquids, and gases, and they are the fastest seismic waves.
Seismic waves travel through the Earth's interior, primarily through solid rock. They can also travel through other mediums such as magma and other materials found in the Earth's crust and mantle. The speed and direction of seismic waves change as they encounter different materials with varying densities and properties.

A P-wave (primary wave) is expected to have the greatest wave speed among seismic waves, traveling through solids, liquids, and gases. P-waves are compressional waves that can travel through the Earth's interior with the highest velocity compared to other types of seismic waves.
The speed of the waves depends on the density of the material.
