These plates aren’t just sitting there. They’re constantly sliding, colliding, and diving under each other at the speed your fingernails grow. Creepy, right?
This slow dance is why we have earthquakes, volcanoes, and entire mountain ranges like the Himalayas. The Himalayas? They started when the Indian Plate slammed into the Eurasian Plate like a car crashing into a brick wall—at two inches per year.
Imagine that: two continents having a slow-motion car crash for 50 million years. That’s why Mount Everest exists.

Except this egg is 7,900 miles wide, and the cracks are thousands of miles long. One plate, the Pacific Plate, is the size of five United States.
And get this: some plates are dense and heavy, like the ocean plates, while others are buoyant and light, like the continents. It’s a floating jigsaw where some pieces sink and others ride high.
