Good luck! ~K
Seismic waves change speed when they encounter boundaries between different materials in the Earth's interior. These boundaries can be caused by changes in temperature, pressure, or composition, which lead to variations in the density and stiffness of the materials. This change in speed is known as refraction and can help seismologists study the structure of the Earth's layers.
It all depends on the intensity that plates grind together with, if they grind with little force you don't get much of a seismic reaction; however if the collide with a great amount of force then there is more energy behind it causing a the powe and speed of a seismic wave to change.
When they pass through different substances
...they pass through a material of different density.
they use vaginas

Acceleration is a change in speed or direction. Velocity is the speed and direction. ex. 41 mph northeast
The bending of a seismic wave as it crosses a boundary is called refraction. This occurs due to the wave changing speed as it moves from one material to another with different properties, causing it to change direction.
A force must be applied to that object according to Newton's First Law of Motion in order to change the speed and its direction.
L waves
change in speed is acceleration. change in speed is the slope of the speed versus time graph, or the derivative of such.
it is the mohorovic or the moho

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

When seismic waves hit the Moho (MohoroviΔiΔ discontinuity), they can either be reflected back to the surface, refracted as they pass through the boundary, or converted into a different type of wave. This boundary separates the Earth's crust from the underlying mantle, resulting in changes in seismic wave behavior.
Speed up
a more rigid material
Seismic waves are waves that travel through the Earth or other elastic body2 to 8 kilometersThe primary factor is the composition of the rock that the wave travels through. Secondarily, temperature tends to lower the wave speed and pressure tends to increase the wave speed.
The boundary between the mantle and the outer core is a layer known as D". It is a thermal and chemical boundary where a change in speed of seismic waves has been noted.
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.
