How Water Travels
When the sun shines on a lake or ocean, it warms up the water, making it turn into vapor, like when you blow on a cold drink and see steam rise.
This vapor rises high up in the sky, where it meets cooler air. Then it changes back to tiny drops of water, forming clouds.
When those clouds get heavy, they drop their water as rain or snow, just like how you pour water from a glass into a cup.
That water then flows down hills and into rivers, lakes, or even oceans, and the cycle starts again!
It's like your toy going back to its starting place so you can play all over again.
