About 71% of Earth’s surface is water. That’s a lot of wet stuff.
But here’s the kicker: 97.5% of that is salty ocean water. You can’t drink that unless you want to shrivel up like a raisin.
So, the water we actually drink comes from the tiny fraction left over. We’re fighting over the leftovers, basically.
The Secret Life of a Water Drop
Your glass of water has a crazy travel itinerary. It might have been an iceberg in Greenland last year.
Or maybe it was sweat on a llama in Peru. Or a teardrop in a romantic comedy.
Here’s how the drop gets to your glass. It’s a road trip with four weird stops.
Stop 1: The Sky Toilet
The sun heats up a puddle, a lake, or your dog’s water bowl. The water turns into vapor and floats up.
This is called evaporation. It’s basically the sky sucking up moisture like a giant, invisible straw.
Once it’s up there, it gets cold. The vapor turns back into tiny droplets. That’s a cloud.
Stop 2: The Cloud Traffic Jam
Clouds are just millions of water droplets bumping into each other. Think of it as a really slow, wet mosh pit.
When the droplets get too fat, they can’t float anymore. They fall as rain, snow, or hail.

Sometimes it’s snow. A single snowflake can contain up to 200 ice crystals. That’s a lot of frozen math.
Stop 3: The Underground Parking Lot
Rain hits the ground. Some of it runs into rivers (that’s surface water).
But a lot of it soaks deep into the ground. It seeps through sand and rock, like coffee through a filter.
This becomes groundwater. It can sit underground for thousands of years. It’s the world’s slowest, most secret swimming pool.
