Now, heat gets water up into the sky, but gravity is the one that brings it back down to Earth. You can’t see gravity, but you feel it, especially after a long run or when you drop your phone. Water feels it, too.
Once water vapor rises high enough, it cools down, turns back into tiny droplets, and forms clouds. When those droplets get too heavy for the cloud to hold, gravity takes over. Down comes the rain. That’s the simplest and most beautiful part of the cycle: what goes up must come down.
Think about it like this: You’re holding a wet sponge over a sink. The more water you squeeze into it, the heavier it gets. Eventually, you can’t hold it anymore, and gravity pulls the water out. That’s exactly what a cloud does—it’s just a fluffy, floating sponge that eventually gets too full.
Stages Of The Water Cycle In Order
Gravity also does the second part of the job: it pulls the rain downhill. All that water runs into streams, which run into rivers, which eventually make their way back to the ocean. This is called runoff. Water is basically on a nonstop slide, coasting downhill thanks to gravity’s gentle nudge.
And the groundwater? That’s gravity’s quiet work, too.
Some water soaks into the ground, filtering through soil and rock. Gravity pulls it deeper and deeper until it settles in underground aquifers. This is the water that fills your glass at a well, and it only got there because gravity took it on a slow underground road trip.
