Secrets Revealed Inside the Earth’s Core

Geology is an amazing subject. Especially now when so much is happening around the world in terms of volcanic eruptions and seismic activities. Let’s review how the interior of the Earth is structured. We’ll take a journey into the depths of the Earth, down through the crust and mantle, nearly to the core. We’ll use seismic waves to show the way, since they echo through the planet following an earthquake and reveal its internal structure, like radar waves.
