Determining Earth's Interior

Scientists have determined the internal layers by...

• Creating a map using seismic waves
• Creating a map using information gathered by satellites
• Drilling and digging to the layers underneath
• All choices

Scientists can find oil and gas underneath us by...

• Creating a map using seismic waves
• Creating a map using lasers
• Drilling and digging 
• All choices

Scientists can find metals underneath us for mining so that we can make steel by...

Seismic waves are vibrations that travel through Earth and are caused by

• Earthquakes
• human made blasts 
• volcanic eruptions
• All choices

which type of waves cannot pass through the liquid outer core?

• p waves
• s waves

When an earthquake on one side of Earth produces S-waves there is a large area on the other side where they can't be detected. This is called the

• P-shadow
• S-shadow
• S-zone
• P-zone

Vibrations that travel through the Earth's interior are called?

• P Waves
• S Waves
• Seismic Waves
• Vibrational Waves

The green seismic body waves are...

• S Waves because they don't travel through the outer core
• P Waves because they don't travel through the outer core
• S Waves because they refract as they hit the outer core
• P Waves because they refract as they hit the outer core

Each layer of Earth is made up of something different

• True
• False
