What are differences between the two surface waves?
P' waves and 'S' waves are both seismic waves that travel through the Earth. 'S'waves are unable to go through any liquid. 'P' waves, on the other hand, can go through both solids and liquids.
What do primary and surface waves have in common?
Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
How does the structure of the earth's interior affect seismic waves?
Earthquakes are made up of 4 different seismic waves, P, S, L and R. L and R are surface waves, and have virtually nothing to do with the interior. However, P and S are body waves and do. P waves are compressional waves, that is they push and pull against rock in the same direction as the waves move. They are the fastest. S waves vibrate material up and down. Both travel faster in more dense material, and P waves travel slower in liquid while S waves are unable to move through liquid at all. As the Earth's outer core is liquid, and inner core is very dense, this affects the waves as they travel through the Earth. It speeds them up and slows them down according to the density. Because S can't go through the outer core, there is a "shadow zone" at a certain area on the Earth where there are no S waves at all. P waves also have a smaller shadow zone, where the waves are diflected and bent within the outer core.
How do people now about earth layers?
From earthquake waves. There are 2 types of waves, p or primary waves and s or secondary waves that are generated when an earthquake occurs. Both types of waves move away from the epicenter of the earthquake in all directions including "down" through the layers of the Earth under the epicenter. Both waves start out at the same time from the same spot, but P waves move through the earth faster, hence the name primary waves. The farther the earthquake monitoring equipment is from the epicenter the bigger the lag time between when the p and s waves arrive. Monitoring stations on the side of the Earth opposite the epicenter do not receive any S waves. This is because S waves only move through solids so when the S waves hit the liquid outer core, the energy from these waves dissipates. When you move out far enough perpendicularly from the epicenter, S waves show up again on monitors. By overlapping these "shadow zones" from multiple quakes around the world, the depth at which the liquid outer core begins can be determined.
What type of seismic wave can pass through the Earth's mantle and core?
There are two types of waves ; P waves and S waves . P waves can travel through solids , liquids , and gases . S waves can only travel through solids . The mantle is pure solid rock ; the outer core is made of liquid-iron and nickel . In other words , only P waves can travel through both the mantle and the core . Hope this helps ! Give thanks to 7th grade Earth science ! :D
What is the area of the earth that is unaffected by both P and S waves?
The shadow zone
What is the area of the earth that is unaffected by both P S waves?
The shadow zone
What is the area of the earth that's unaffected by both p and s waves?
none, p-waves can travel anywhere
He area of earth that is unaffected by both p and s waves?
No, but P and S waves are used for earthquakes..and everybody should know that p waves come befoe s waves during an earthquake and maybe even during an aftershock....
What area of earth is not affected by both p and s waves?
The liquid outer core of the Earth's interior refracts p-waves at the boundary with the mantle, and does not carry s-waves.
What are the differences between the waves?
P' waves and 'S' waves are both seismic waves that travel through the Earth. 'S'waves are unable to go through any liquid. 'P' waves, on the other hand, can go through both solids and liquids.

What do primary and surface waves have in common?
Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
What do vertical and horizontal surface waves have in common?
Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
What techniques do you find in common between how we probe the internal structure of the Sun and the internal structure of Earth?
We use seismic waves (or pressure waves) to interpret the internal structure of both the sun and earth. When studying the sun it is called helioseismology on earth it is just called seismology

Is polarization a property of transverse waves longiudinal waves or both?
both
