The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.

## Why are P waves received but S waves are not received by seismic stations?

Answer: P and S waves are types of seismic waves . The reason whey P waves are received but S-waves are not received by seismic stations located on the opposite side of Earth from an earthquake epicenter is because those waves(S-waves) cannot travel through the liquid core of the earth.

## Which statement best describes the arrival of P waves and S waves?

S waves are slower than P waves, even if emitted at the same time. In this case, we can say that if a station is located close to the earthquake epicenter, the station would receive these waves quickly. The P wave would be received first, since it has a higher speed, the S wave would arrive soon.

## How are S waves and P waves similar?

How are S waves and P waves similar? They shake the ground. They travel through liquids. They arrive at the same time.

## Why are seismic P waves called primary waves?

P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel. They are called primary waves because they are the first type of wave to arrive at seismic recording stations.

## Why do P waves arrive first?

The direct P wave arrives first because its path is through the higher speed, dense rocks deeper in the earth. The PP (one bounce) and PPP (two bounces) waves travel more slowly than the direct P because they pass through shallower, lower velocity rocks. The different S waves arrive after the P waves.

## What is the movement type of P wave?

Seismic P waves are also called compressional or longitudinal waves, they compress and expand (oscillate) the ground back and forth in the direction of travel, like sound waves that move back and forth as the waves travel from source to receiver. P wave is the fastest wave.

## How are tsunamis generated?

Tsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.

## Why do geologists believe the inner core is solid?

Why do geologists believe the inner core is solid? P-waves refract at the boundary between the outer core and inner core. If S waves arrive on the opposite side of the planet, then the core is solid.

## How do we know the inner core is solid?

Metals such as iron are magnetic, but rock, which makes up the mantle and crust, is not. Scientists know that the outer core is liquid and the inner core is solid because: S-waves do not go through the outer core.
