Answer 1

Answer:

Core structure

Core structureMost of what we know about the interior of the Earth comes from the study of seismic waves from earthquakes. Seismic waves from large earthquakes pass throughout the Earth. These waves contain vital information about the internal structure of the Earth.

Instead of using CAT-scans and X-rays to see the center of the Earth, researchers use waves emitted by earthquakes to get a sense of the planet's innards. Just like an X-ray, seismic waves bounce around, changing direction and speed based on the material they pass through
