Earth's Outer Core Flow Reverses Direction Under Pacific Ocean

Scientists have observed an unexpected reversal in the flow direction of molten material within Earth's outer core beneath the Pacific Ocean. Previously thought to flow predominantly westward, a significant region shifted strongly eastward in 2010, as revealed by ESA satellite data. This discovery challenges existing models of core dynamics and highlights the complex nature of Earth's interior, which is responsible for generating the planet's geomagnetic field. The implications for the geomagnetic field require further study.
