Are rocks alive? The truth about the egg-laying rocks of China’s Guizhou province
In China's Guizhou province, smooth oval stones emerge from cliff faces, a geological phenomenon locals call "egg stones." Scientifically known as concretions, these form over millions of years as minerals cement within softer rock, eventually being exposed by erosion. This natural process, occurring every few decades, has inspired generations of folklore and continues to draw tourists.
