Rain's Wild Ride
Where does rain come from?
Rain starts with the sun — which sounds backwards, right? The sun doesn't make things wet, it makes them hot. But here's the trick: that heat is what kicks off the whole wild ride that ends with drops landing on your head.
When the sun heats up oceans, lakes, and rivers, it turns some of that water into vapor — an invisible gas that floats up into the air. You can't see it happening, but billions of water molecules are escaping right now, drifting upward like they're trying to fly.
