WIRED ScienceThe Lava That Doesn’t Erupt Anymore
Volcanoes have been a persistent feature on Earth since the planet condensed out of the primordial nebula of our solar system. The scale and style of that volcanism has changed dramatically over that 4.5 billion years—heck, after Thera bumped into proto-Earth to form the Moon, we probably had a planet-wide lava lake as the molten Earth coalesced and cooled from the collision. However, we lack much of a record of that tumultuous time beyond a few zircon found in younger sediments.
