LAB FLASHCARD What can you tell from studying seismic waves?

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, typically as a result of geological activity such as earthquakes.

Front

What are the two main types of seismic waves?

Back

The two main types of seismic waves are P-waves (primary waves) and S-waves (secondary waves).

Front

What is the primary characteristic of P-waves?

Back

P-waves are compressional waves that can travel through solids, liquids, and gases.

Front

What is the primary characteristic of S-waves?

Back

S-waves are shear waves that can only travel through solids.

Front

Why do S-waves stop at the outer core?

Back

S-waves stop at the outer core because the outer core is liquid, and S-waves cannot travel through liquids.

Front

What happens to P-waves when they reach the outer core?

Back

P-waves bend as they enter the outer core due to the change in density and state of matter.

Front

What is the composition of the Earth's outer core?

Back

The Earth's outer core is primarily composed of liquid iron and nickel.

Front

What is the composition of the Earth's inner core?

Back

The Earth's inner core is primarily composed of solid iron and nickel.

Front

How does the Earth's magnetic field protect us?

Back

The Earth's magnetic field protects us from solar radiation and charged particles from the sun.

Front

What is the significance of studying seismic waves?

Back

Studying seismic waves helps scientists understand the Earth's internal structure and the processes that occur within it.
