How seismic waves revealed the hidden layers of our planet
In short: By analyzing how different types of earthquake waves travel through the ground, scientists were able to map the interior of the Earth without ever digging a hole.
The video explains how S and P waves serve as tools for deep-earth exploration. By observing these seismic movements, researchers discovered that the Earth is not uniform but possesses a distinct layered structure.
Key findings include the identification of a solid inner core encased within an outer liquid core. This knowledge was made possible by studying the specific behaviors of S and P waves as they propagate through various materials.
