You’re standing on solid ground… or are you? New research has uncovered something shocking: parts of North America’s foundation are literally melting away — and it’s not from an earthquake or a sinkhole. Scientists used 3D imaging of Earth’s interior and found that nearly 37 miles of rock have dripped away into the mantle, like molten cheese off a pizza. The culprit? The ancient cratons — the billion-year-old roots of continents — are breaking down beneath our feet.

This video explores how our supposedly stable ground is changing, why it matters, and what it could mean for the future of the continent. Trust us, this is way more important than it sounds.
