There Are Mountains Deep Within the Earth

The video explores the complex structure of Earth's interior, challenging the traditional view of neat layers. It highlights the discovery of a mountain range between the upper and lower mantle, which may hold clues to Earth's missing elements. Seismic waves from earthquakes help scientists study these deep regions, revealing rough and chemically distinct mantle boundaries. These findings suggest ancient oceanic crust may be trapped in the mantle, potentially containing hidden elements. The video emphasizes the dynamic and intricate nature of Earth's structure.
