Rain's Patient Sculpture
How are caves formed underground?
You walk into a cave and the world opens up — a hidden room carved into solid rock, as if someone hollowed out the mountain with a giant spoon. Who dug this? When? And how did they know exactly where to scoop?
No one dug it. The cave carved itself, one raindrop at a time, over millions of years. Rain is the patient artist here. When raindrops fall through the air, they pick up carbon dioxide and turn slightly acidic — not vinegar-sour, just enough to be a very slow rock-melter.
