Discovery of Underground Mountain Ranges in Antarctica

Samantha Hansen, a geologist, led a team in Antarctica to study the Earth's interior. Using seismic waves from earthquakes, they found massive underground mountain ranges beneath the Earth's mantle. These structures called ultra-low velocity zones, distorted seismic waves and stand out due to their unique characteristics. These underground mountains might be made of pieces of ancient oceanic sea floor that have been subducted deep into the Earth over millions of years. This discovery challenges our understanding of how the Earth functions and could shed light on important geological processes and the planet's ability to support life.
