How are mountains made?

Mountains look like they've been standing forever — solid, still, ancient. But here's the wild part: they're not finished yet. Right now, while you're reading this, mountains are slowly growing, crumpling, and shoving themselves higher into the sky.
The secret is hiding under your feet. Earth's surface isn't one solid shell — it's cracked into enormous pieces called tectonic plates, like a planetary jigsaw puzzle. These plates float on hot, gooey rock deep below, drifting a few centimeters every year. About as fast as your fingernails grow.
