How does rain form and what is the water cycle?

Rain is when water from the sky falls down to Earth because it got too heavy and cold.

Imagine you're playing with a ball in a pool. You throw the ball up, and it goes higher and higher until it can’t go any further, then it comes back down. That’s kind of like what happens with water vapor in the air.

When the sun warms up water from lakes, rivers, or even puddles, some of that water turns into vapor (like steam from a hot soup). This vapor goes up into the sky and cools down as it rises. When it gets cool enough, the vapor changes back into tiny drops, these are clouds.

If lots of drops join together in the clouds, they get heavy and fall down to Earth as rain. It's like when you pile too many toys on your bed, eventually, the bed can't hold them all anymore!

The water cycle is like a never-ending game of hide-and-seek between water and the sky. Water from Earth goes up into the sky (this is evaporation), turns back into rain (condensation), then falls again, and the whole process starts over! It's how we get fresh water for lakes, rivers, and even your bathtub!
