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.

How the structure of earth interior affects seismic waves speed and direction?

The structure of Earth's interior affects seismic wave speed and direction differently at different boundaries. As P waves enter the mantle, they pick up speed until they enter the core, where the wave paths are bent sharply.


How does the composition of earths interior effect an earthquake?

The composition of Earth's interior affects earthquakes by influencing the propagation of seismic waves. The different layers, such as the crust, mantle, and core, have varying densities and properties that impact how seismic waves travel through them. This influences the speed, direction, and intensity of seismic waves during an earthquake.


Why do seismic waves change speed?

"True, the Seismic Waves change speed and direction when they encounter different materials."


What happens to seismic waves in the air?

In air, the seismic waves(P-wave) are simply sound waves, and travel with the speed of sound (approx. 335 m/s).


What is ther kind of seismic wave that travels fast and increase its speed with depth?

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.


What is the effect of pressure and speed in sound waves?

Speed affects the frequency and pressure affects the wavelength.


What is the speed of seismic waves from the fastest to the slowest is it p waves s waves l wave or all three?

The speed of seismic waves from fastest to slowest is P waves (primary waves), S waves (secondary waves), and then surface waves. L waves are a type of surface wave, so they are generally slower than both P and S waves.


Which seismic wave moves through Earth at the fastest speed?

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.


Seismic waves increase in speed when they enter what?

Seismic waves increase in speed when they enter more rigid materials, such as solid rock or the Earth's mantle. This increase in speed is due to the higher elasticity and density of these materials, allowing the waves to propagate faster.


Where is the place within the earth where the speed of seismic waves increases sharply?

The place within the Earth where the speed of seismic waves increases sharply is known as the Moho discontinuity, or Mohorovicic discontinuity. This boundary separates the Earth's crust from the underlying mantle, and seismic waves are thought to speed up due to the change in composition and density between these two layers.


What is a place inside the earth where the speed of seismic waves increase sharply?
