P waves: the rock spring back to its original shape
S waves: the rock is deformed from side to side
Surface waves: the rock goes up and down

Seismic waves travel through Earth's layers at different speeds depending on the what?
Density and the composition of the different layers affect the behavior of seismic waves.
What are three things that can happen to wave as it moves through different materials?
Seismic waves change speed as they travel through Earth because of the four different layers. The layers differ, changing from a thin crust, to a rocky mantle, a liquid outer core, and finally a solid metallic core. Each of the layers affect the speed of seismic waves due to the differences in their makeup. They move faster through the crust and mantle than they do through the cores. In fact, "S" waves are unable to move through the liquid outer core at all.
Why doesn't the triangulation method give an exact location of an earthquake's epicenter?
In order to locate an earthquake's epicentre it is necessary to calculate the distance of the epicentre from the seismometer stations that recorded the seismic waves. To do this, it is necessary to know the velocity of the P and S seismic waves through the Earth's crust. This velocity is in turn dependent on the density and elastic moduli of the material that the seismic waves travel through. As the Earth is formed from a very wide variety of rocks that have different properties and have undergone differing levels of deformation as well as chemical and other physical changes, the relevant properties can be very variable. Because of this, seismologists cannot know the exact nature of all the material that the seismic waves must travel through and therefore have to create simplified models of the ground in order to estimate the seismic wave speed and in turn estimate the distance to the epicentre. This approximation and simplification will introduce an error into the result and this will mean that the position of the epicentre will be approximate. Normally the margin of error will be quoted along with the best estimate of the location. For more information on the methodology used for the triangulation of earthquake epicentres and the parameters that affect the velocity of seismic waves, please see the related questions.
Explain three factors that affect the rate of stream erosion?

How can filled land and loose soft soil affect the amount of damage caused by an earthquake?
The amplitude (size) of seismic waves is affected by the material through which they travel. Soft soil and fill causes the seismic wave amplitude to increase and therefore this allows them to cause more damage to structures. Also soft ground and certain types of soil are prone to a phenomenon known as liquefaction which can cause damage to buildings. For more information, please see the related questions below.

Does Hydraulic Fracturing for natural gas affect seismic activity?
yes hydraulic fracturing of natural gas does effect seismic activity.
How does earths solid inner core affect seismic waves?
They go faster through the inner core than the liquid outer core.
What is a seismic wave?
A seismic wave is mechanical energy, and it arises in earthquakes or other shifts that affect the crust of the earth. The energy is transferred through the crust and core in wavesthat we identify as P-waves and S-waves. A link is provided below for more information.
Does the size of a core of a planet affect seismic activity on the surface?
yes
How do seismic waves affect us?
Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.
