Due to the movement of Earth’s tectonic plates, our planet’s crust is constantly recycled, making rocks and minerals from its earliest days incredibly rare. That’s frustrating for geologists, since surface-level Hadean rocks (rocks older than 4.03 billion years) could provide significant insight into the first geological stages of Earth’s 4.5-billion-year history. In a study published […]
How Did This 1,300-Ton Boulder Travel Up a Cliff? Scientists Just Figured It Out
A giant boulder in Tonga rode a wave from an ancient tsunami 7,000 years ago. The 1,300-ton rock traveled a distance twice the size of a football field, swept away by the sheer force of the wave, according to a new study. But this was no ordinary giant rock. It was also sitting on a […]
New Evidence Bolsters Theory of Megaflood That Refilled the Mediterranean Millions of Years Ago
Millions of years ago, the Mediterranean Sea evaporated. It may have then been refilled by the largest flooding event ever experienced on Earth. An international team of researchers has uncovered new evidence supporting the Zanclean megaflood, a theorized event that refilled the Mediterranean Sea after the Messinian Salinity Crisis had transformed it into a dry, […]
