What do P and surface waves have in common?

What do P and surface waves have in common?

-Body waves travel within Earth, and surface waves travel along Earth’s 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. -Rocks within Earth both expand and contract as P waves pass.

How are S waves and P waves similar both arrive after P waves?

S waves are called secondary waves because they always arrive after P waves at seismic recording stations. Unlike P waves, S waves can travel only through solid materials. After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth’s surface.

How do P waves and S waves travel through solids and liquids?

In a P wave, the rock particles are alternately squished together and pulled apart (called compressions and dilatations), so P waves are also called compressional waves. These waves can travel through solids, liquids, and gases. P waves can travel through the liquid outer core. An S wave is a different beast.

What happens to P waves and S waves as they travel inside the Earth?

The speed of P waves and S waves increases as they travel deeper into the Earth’s mantle . They travel through the Earth in curved paths, but they change direction suddenly when they pass through the boundary between substances in different states.

Which of the following is a characteristic of an S wave?

S-waves are shear waves (though that is not what the S stands for). They move by material flexing or deforming sideways (shearing) from the direction of wave travel, and then returning to the original shape once the wave passes.

What are the typical characteristics of S waves?

S-waves are transverse waves. Even though they are slower than P-waves, the S-waves move quickly. Typical S-wave propagation speeds are on the order of 1 to 8 km/sec. The lower value corresponds to the wave speed in loose, unconsolidated sediment, the higher value is near the base of Earth’s mantle.

Do P and S waves travel through solids?

P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. These waves can travel through solids, liquids, and gases. P waves can travel through the liquid outer core. An S wave is a different beast.

Do both P and S waves travel through solids?

Surface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids.
