Which type of seismic wave is the fastest?
P-waves
100
How do S-waves move?
Perpendicular to their direction of travel
100
What waves travel through earth solid crust?
P and S waves
100
What waves travel through mantle?
P waves
100
Who realized that s waves do not travel through earths center?
seismologists

What makes up the upper mantle according to seismic wave studies?
The upper mantle is composed of peridotite, primarily consisting of olivine.
200
How are seismic wave images created?
Seismic wave images are created using seismometer measurements worldwide
200
Which type of waves move horizontally, perpendicular to their direction of travel?
Love Waves or L-wave
300
How does the study of shadow zones help scientists understand the outer core?
It confirms the outer core is liquid since S-waves cannot pass through it
300
What changes do seismic waves undergo in the Earth's mantle?
Seismic waves change speed and direction at material boundaries, indicating density and composition variations.

What do p-waves travel through
The mantle, outer core and inner core.

What is a shadow zone?
A area in the earths surface where sesimographs cannot detect direct p and s waves from an earthquakes

What type of seismic waves are transverse and move perpendicular to their direction of travel?
Secondary Wave or S-waves
400
What are xenoliths and how are they brought to the surface?
Xenoliths are fragments of mantle rock brought to the surface by volcanic eruptions.
400
What happens to temperature as depth increases within the Earth?
It increases
400
Why do seismic waves bend as they travel through Earth’s interior?
Due to the changing density of materials inside the Earth
500
If a volcanic eruption ejects xenoliths, what can scientists learn from them?
The composition of the mantle
500
In what ways do seismic waves reflect and refract at different boundaries inside Earth?
Seismic waves reflect and refract at material boundaries
500
What instrument is used to detect and record seismic waves?
Seismograph
500
What type of waves are compression waves that move particles back and forth parallel to the direction of propagation?
Primary Waves
500
Why do seismologists use triangulation?
To locate the earthquake's epicenter
