How do scientists know what the earths interior is like?
scientists can tell what the interior looks like by the different type of waves there is. scientists know that P (primary) waves can travel through any substance, and that S (secondary) waves can travel only through solids and stop at liquids when P waves slow down at liquids. when they monitor the p and s waves they realize that after a certain distance (2932 km) the s waves stop and p waves slow down. thus meaning it is in the liquefied outer core. but after a certain amount of time the p waves speed up again. this means it has left the outer core into the solid inner core.
What does the S wave and P wave stand for?
P waves are primary waves and S waves are called secondary waves
When do P waves arrive at the surface in relation to S waves?
when the P waves arrive at the surface in relation to s waves and surface waves is called the promary waves.
What directions does P waves and S waves go?
P waves go side to side. S waves go up and down.
Do surface waves move faster than P-waves or S-waves?
No. Surface waves are slower than both P and S-waves.
What are two factors scientists monitor that could indicate a volcano might erupt?
s-waves and p-waves
How have scientists determined that the outer layer is liquid?
Seismic waves can be separated into basically two different types; S-waves and P-waves. P-waves are able to travel through liquid and solid, but S-waves can not travel through a liquid, they can only travel through a solid. When scientist "shoot" P and S-waves at the outer core, they detect the P-waves coming out the other side, but not the S-waves.

How did you discover that the outer core was liquid?
It was observed that p (pressure) waves from earthquakes passed through the core bus s (sheer) waves from earthquakes did not.
Are P-waves and S-waves transverse or longitudinal waves?
P-waves are longitudinal and S-waves are transverse waves.
What type of seismic wave are P waves and S waves?
P and S waves are body waves.
What do scientists use to calculate the distance from the seismograph station to the focus?
The diffrence in arrival times of P and S waves.
What two things do scientists use P and S waves for?
To determine the approximate location and the time the earthquake will occur.
What is the difference Between S waves P waves?
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
What does the S wave and P wave stand for?
P waves are primary waves and S waves are called secondary waves
What are the three seismic waves in order?
The three types of seismic waves are: P waves S waves Surface waves ( two surface waves. Riley surface wave and love surface wave named after scientists
When do P waves arrive at the surface in relation to S waves?
when the P waves arrive at the surface in relation to s waves and surface waves is called the promary waves.
