Final answer:
Scientists use core samples, earthquakes, and S-waves to study the Earth's interior.
Step-by-step explanation:
Scientists use several sources to study the interior of the Earth. These include core samples, earthquakes, and S-waves.
- Core samples: Scientists drill deep into the Earth's crust to collect samples of rock and sediment. By analyzing these samples, they can study the composition and structure of the Earth's interior.
- Earthquakes: Seismic waves produced during earthquakes provide valuable information about the Earth's interior. Scientists analyze how these waves travel through different layers to understand the properties of the Earth's interior.
- S-waves: S-waves are a type of seismic wave that only travels through solids. By studying how S-waves propagate through the Earth, scientists can determine the presence of different layers and their properties.
