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.

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 place within the earth where the speed of seismic waves increases sharply?
The Moho
A place within the earth where the speed of seismic waves increases sharply?
m to the o to the h to the o
What are seismic waves also called?
Seismic sea waves are also called a tsunami.
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.

What happens to seismic waves when they hit the MOHO?
They speed up
Which seismic wave moves through Earth at the fastest speed?
p-waves which is primary waves
Seismic waves increase in speed when they enter what?
a more rigid material
What is the effect of pressure and speed in sound waves?
Speed affects the frequency and pressure affects the wavelength.
What is a place inside the earth where the speed of seismic waves increase sharply?
MOHO(:
Where is the place within the earth where the speed of seismic waves increases sharply?
Moho
What place within the earth where the speed of seismic waves increases sharply?
The Moho
Is seismic waves and earthquake waves the same?
Seismic waves are any waves that travel through the Earth. As such all earthquake waves are seismic waves, however not all seismic waves are caused by earthquakes.
Do seismic waves speed up or slow down as they travel downward and reach the Moho?
Speed up
