Here’s a wild fact: The massive eruption of Deccan Traps in India—a flood of igneous basalt over a million years—might have helped push the dinosaurs toward extinction. The volcanic gases changed the climate long before the asteroid hit. Talk about a slow burn.
On a lighter note, Roman concrete—which still stands today—mixes volcanic ash (called pozzolana) with lime. That ash is basically pulverized igneous rock. The Colosseum is standing because of ancient volcano trash. Sustainability win.

The world’s largest monolith, Uluru (Ayers Rock) in Australia, is made of sandstone, but the world’s largest single igneous rock is probably Ayer’s Rock’s cousin: the Bishop’s Peak in California. Nah, it’s actually Stone Mountain in Georgia—a massive dome of quartz monzonite. It’s bigger than a skyscraper and entirely solid.
