Ancient sea levels reveal when the Earth's poles went wandering
60-Word AI Digest
Earth's poles do not always stay in the same place. For example, a region once near the North Pole can end up near the equator, and an area near the equator can shift up toward the pole. This is known as true polar wander (TPW), and it's when Earth's crust and mantle shift together relative to...
