Rock's Endless Journey
How are rocks formed and what is the rock cycle?
Pick up a pebble. Hold it. That little gray nothing in your palm is older than every dinosaur, every ocean, every breath ever taken — and here's the wild part: it isn't finished. Rocks don't sit still forever. They travel, melt, crumble, and remake themselves in a slow, looping journey called the rock cycle. Let's follow one rock around the loop.
Our story starts deep underground, where it's so hot that rock turns into thick, glowing liquid called magma. When magma cools, it hardens into the first kind of rock: igneous rock. If it cools slowly deep below, it grows chunky crystals, like granite. If it bursts out of a volcano and cools fast in the air, it freezes into smooth, dark rock almost instantly.
