Sound (unlike ocean waves) is a pressure wave, not a transverse wave. Pressure waves (as the name suggests) are waves the oscillate in the direction that they are moving, hence have a pressure difference. If you bang a piece of steel with a hammer, then you are momentarily changing the pressure in the steel at that point. The pressure change moves along very rapidly, and your ears pick that up as sound. Because the atoms in a solid are much closer together than the atoms in a gas, sound can travel much, much faster in a solid than a liquid or a gas.

What are two types of seismic waves that travel through earth's interior?
The two types of seismic waves that travel through the Earth are P and S waves. The P wave means primary wave and the S wave is secondary. The wave that travels around the Earth's crust is the L wave, which stands for the Love wave.Hope this helps :)
What type of seismic wave does not travel through the core?
Surface waves, also known as Love and Rayleigh waves, do not travel through the core of the Earth. These waves move along the surface of the Earth and are responsible for the most destruction during an earthquake.
What happens to P- and S- waves when they reach the center of the earth?
P waves travel much faster than S waves so they reach the core faster. They can travel through the outer core, but change direction slightly, causing a p-waves shadow zone. S waves cannot travel through the outer core because it is liquid and has zero rigidity so they are diverted around it causing a much larger shadow zone called the S wave shadow zone. Surface, or L waves cannot travel through the earth at all. P-waves are observed directly opposite to the epicentre of earthquake which states that the wave passing through the earth as a diameter has no effect on its path.
What does the L in l-waves stand for?
l waves are the slowest our waves . They are also called "Long Waves" . They travel along the surface of the Earth . They are the ones that people notice the most .
What are P S and L waves?
They are seismic waves - those emitted by an earthquake. P-waves are known as primary waves. They have the fastest velocity of all the seismic waves and so arrive at a seismometer station first. They are a longitudinal or compression wave. S-waves are secondary waves. They travel more slowly than P-waves, but faster than surface waves so are the second seismic wave to be recorded at a seismometer station. They are transverse or shear waves. Finally there are the surface waves of which there are two main types. The L-wave or Love Wave and the R-wave or Rayleigh wave. These waves tend to have the largest magnitude and cause the majority of the damage that occurs during an earthquake.
What do L waves travel through?
L waves, also known as Love waves, are a type of surface wave that travel through the solid layer of the Earth's crust. These waves move by shaking the ground side-to-side in a horizontal direction. L waves are slower than other seismic waves but can cause significant damage during earthquakes.

What matter do L-Waves travel through?
only through the surface of the earth
What are the three seizmic waves?
The 3 seizmic waves are primary or P-wave, secondary or S-wave and surface or L-wave. P-waves expand and compress material. Particles around the wave vibrate and the P-wave is the fastest wave out of the 3. S-waves travel through the ground perpendicular to the forward motion. these waves are slower than P-waves and these waves travel through solids only! L-waves are the most desructive wave. once you know where this guy hits you know where the epicenter of an earthquake is. L-waves are the combination of P- and S-waves.
How do seismic waves tell us about the properties of the outer and inner core?
We know about the nature of the different kinds of waves because each earthquake produces three kinds of wave: Primary, Secondary and Long (or another variation) waves. L waves only travel at the surface, so these are irrelevant to this question. P waves are longitudinal and can travel through solids and liquids; S waves can only travel through solids. Thus, when P waves travel through the core, but S waves don't, we know the outer core is liquid. We know that the inner core is solid because the amount of refraction of the P waves changes within the core, so it cannot be uniform in composition, so we believe it to have a solid element to it.
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 type of seismic wave does not travel through the core?
Surface waves, also known as Love and Rayleigh waves, do not travel through the core of the Earth. These waves move along the surface of the Earth and are responsible for the most destruction during an earthquake.
What kind of waves are associated with earthquakes?
Seismic waves are associated with earthquakes. These waves travel through the Earth's layers and cause shaking and ground displacement during an earthquake. There are two main types of seismic waves: body waves, which travel through the interior of the Earth, and surface waves, which travel along the Earth's surface.
Which waves come first P-waves L-waves or S-waves?
P-waves typically arrive first during an earthquake, followed by S-waves, and then L-waves. P-waves are compressional waves that travel fastest through the earth's interior, followed by S-waves which are shear waves. L-waves are surface waves that travel along the earth's crust.
What happens to P- and S- waves when they reach the center of the earth?
P waves travel much faster than S waves so they reach the core faster. They can travel through the outer core, but change direction slightly, causing a p-waves shadow zone. S waves cannot travel through the outer core because it is liquid and has zero rigidity so they are diverted around it causing a much larger shadow zone called the S wave shadow zone. Surface, or L waves cannot travel through the earth at all. P-waves are observed directly opposite to the epicentre of earthquake which states that the wave passing through the earth as a diameter has no effect on its path.
Which waves s-waves or p-waves reach a seismograph first why?
The Pressure wave is a longitudinal wave - it is a compression/rarefaction wave and has the highest velocity.The Secondary wave is a transverse wave (side to side) and is much slower.
What does the L in l-waves stand for?
l waves are the slowest our waves . They are also called "Long Waves" . They travel along the surface of the Earth . They are the ones that people notice the most .
