Did you know there’s a 430-mile-long chain of ancient volcanoes buried deep under China’s Yangtze Block? Geologists just uncovered this epic volcanic arc using magnetic sensors and rock samples. Turns out, these volcanoes formed over 800 million years ago when tectonic plates collided, and they may have even helped shake up Earth’s climate back in the day. Imagine what else is hiding beneath our feet! #Science #Geology #Volcanoes
