Scientists just found massive sand mounds under the North Sea that are literally upside down—like, the older layers are on top and the younger, heavier sand sank below. This wild geological twist is called stratigraphic inversion, and it’s never been seen on this scale before. It could totally change how we think about what’s happening under the ocean floor, especially for stuff like carbon storage. Nature is seriously full of surprises! #Science #science #oceanmystery
