A_24 P and S-Waves

Front

What are P-waves?

Back

P-waves, or primary waves, are seismic waves that compress and expand the material they move through, traveling forward and backward.

Front

What are S-waves?

Back

S-waves, or secondary waves, are seismic waves that move the ground side to side and can only travel through solids.

Front

How do P-waves differ from S-waves in terms of travel medium?

Back

P-waves can travel through both liquids and solids, while S-waves can only travel through solids.

Front

What is the first type of seismic wave to arrive at a location from an earthquake's epicenter?

Back

P-waves are the first waves to arrive at any location from the epicenter.

Front

Which seismic wave is considered the most destructive?

Back

S-waves are considered the most destructive seismic body waves.

Front

What is the relationship between the distance from the epicenter and the arrival time of P-waves and S-waves?

Back

P-waves arrive first, followed by S-waves; the greater the distance from the epicenter, the longer the time difference between their arrivals.

Front

What is the role of seismic stations in earthquake detection?

Back

Seismic stations detect and record seismic waves, helping to determine the location and magnitude of an earthquake.

Front

What type of wave is a surface wave?

Back

Surface waves are seismic waves that travel along the Earth's surface and are typically more destructive than body waves.

Front

What is the significance of the epicenter in an earthquake?

Back

The epicenter is the point on the Earth's surface directly above where an earthquake originates, and it is often the location of the most intense shaking.

Front

How do scientists use the difference in arrival times of P-waves and S-waves?

Back

Scientists use the difference in arrival times to calculate the distance to the earthquake's epicenter.
