# Activity 162 How Seismic Waves Travel Through Earth Answers?

You might also be thinking, How do seismic waves travel through Earth’s activity?

Changes in composition, pressure, and temperature inside the Earth’s strata cause seismic waves to travel along a curved route across it. Seismic waves pass through various materials at varying rates. Two wave fronts collide in this two-layer model at the same moment, but the bottom layer is quicker.

Similarly, How do seismic waves travel through the Earth quizlet?

What is the path of seismic waves? They radiate outward in all directions from the focal point.

But then this question also arises, Do seismic waves travel through Earth?

Seismic waves flow through and around the Earth, and seismometers may detect them.

Which of the seismic waves travels the fastest answer?

P-waves and S-waves are two types of body waves that travel throughout the globe. Because the interior of the Earth does not respond the same way to both, P-waves move 60 percent quicker than S-waves on average.

Which seismic waves travel through the interior part of the Earth?

Body waves (P-waves and S-waves), which travel through the earth’s interior, and surface waves, which move just at the earth’s surface, are the two types of seismic waves.

## How do seismic waves tell us about the Earth structure?

We can learn about the strata of the Earth by studying how waves behave as they flow through various materials. The Earth’s interior is made up of a series of concentric shells, with a thin outer crust, a mantle, a liquid outer core, and a solid inner core, according to seismic waves.

## Why do seismic body waves refract as they travel through the Earth quizlet?

As seismic waves travel through the Earth, they are reflected, refracted, and diffracted. They reflect off the edges of distinct layers, refract while moving from one layer to the next, and diffract around any barriers they come across.

## What is seismic waves quizlet?

What is the entire definition of seismic waves? The energy created during an earthquake is carried by vibrations that pass through the Earth. P waves, S waves, and surface waves are the three kinds of seismic waves.

## What happens to seismic waves as they travel away from the focus?

As seismic waves move away from the focal point, their energy and intensity diminish. Why is it that the biggest damage occurs around the fault? Because the highest quantity of energy is located near the fault, the most damage happens there.

## How far do seismic waves travel through Earth?

P waves move at rates ranging from around 6 km (3.7 miles) per second near the Earth’s surface to about 10.4 km (6.5 miles) per second in the Earth’s core 2,900 km (1,800 miles) below the surface. The waves’ velocity reduces to around 8 km (5 miles) per second when they reach the core.

## Which seismic wave will cause most damage on the earth’s ground?

Love waves have a particle motion that is transverse to the propagation direction but has no vertical motion, similar to the S-wave. Because of their side-to-side motion (like a snake wiggling), Love waves force the earth to twist from side to side, causing the greatest damage to buildings.

## Which seismic wave will cause most damage on the earth’s ground body wave or surface wave?

waves on the surface

## Where do seismic waves travel slowest?

Surface waves propagate outward from the epicenter of an earthquake. The slowest seismic waves are surface waves. 07.05.2021

## How useful are seismic waves in understanding Earth’s interior?

We can learn about the strata of the Earth by studying how waves behave as they flow through various materials. The Earth’s interior is made up of a series of concentric shells, with a thin outer crust, a mantle, a liquid outer core, and a solid inner core, according to seismic waves.

## How do seismic waves help scientists understand Earth’s layers?

Scientists can detect the difference between faraway earthquakes by looking at seismic waves recorded all around the earth’s surface. The seismic waves are reflected (bounced off) by layers of varying densities and refracted (bent) by layers of varying densities.

## How do seismic waves tell us the Earth’s outer core is liquid quizlet?

At the mantle-core boundary, P-waves accelerate, indicating that the outer core is less rigid than the mantle. Seismic waves are reflected or refracted due to the various densities of the earth’s strata (bent.) We know the outer core is liquid because S-waves vanish at the mantle core boundary.

## How are seismic waves used to determine the position and thickness of Earth’s interior layers?

How are the location and thickness of Earth’s inner layers determined using seismic waves? … Seismic waves will be able to travel right through dense rock strata. Seismic waves’ velocity will be increased and their direction will be changed due to refraction in dense inner layers. 01.12.2021

## What type of seismic waves are S-waves quizlet?

What is the complete definition of the S wave? A form of seismic wave that pushes the earth up and down or side to side is known as a secondary wave. S-waves are slower than P waves and cannot pass through liquids.

## What causes seismic waves?

Seismic waves are created when elements inside the Earth move suddenly, such as when a fault slips during an earthquake. Seismic waves may be caused by volcanic eruptions, explosions, landslides, avalanches, and even flowing rivers.

## Which seismic waves travel the fastest quizlet?

What is the complete definition of a P wave? A main wave compresses and extends the earth. This is the fastest sort of wave, and it can pass through both solids and liquids.

## Which seismic wave type travels the fastest quizlet?

What is the complete definition of a P wave? A main wave compresses and extends the earth. This is the fastest sort of wave, and it can pass through both solids and liquids.

## Conclusion

The “p waves and s waves” is a question that has been asked many times before. The answer to this question is that the “P wave travels faster than the S wave.”
