LAB FLASHCARD What can you tell from studying seismic waves?

Front

What are the two main metals that make up the outer and inner core?

Back

Iron & Nickel

Front

What do S-waves do when they meet the outer core?

Back

They stop.

Front

What does the Earth's magnetic field protect us from?

Back

Solar radiation.

Front

Why do seismic waves change direction?

Back

Due to the change in density and composition of the materials they pass through.

Front

Why does the speed of seismic waves change when they reach the outer core?

Back

The outer core is liquid.

Front

What are seismic waves?

Back

Waves of energy that travel through the Earth, typically generated by earthquakes.

Front

What are the two main types of seismic waves?

Back

P-waves (primary waves) and S-waves (secondary waves).

Front

How do P-waves differ from S-waves?

Back

P-waves are compressional waves that can travel through solids and liquids, while S-waves are shear waves that can only travel through solids.

Front

What is the significance of studying seismic waves?

Back

They help scientists understand the Earth's internal structure and the dynamics of earthquakes.

Front

What is the outer core primarily composed of?

Back

Liquid iron and nickel.
