One summer day a raindrop fell from a cloud. Many other raindrops fell at the same time, but our story is about just one raindrop.
The raindrop fell to the ground on the side of a hill. The water in the raindrop ran down the hill into a little river. The little river carried the raindrop to a big river. Then the raindrop traveled far to the east into the sea. There the water of the raindrop mixed itself with the salt water of the sea.
Now the water of the raindrop was on the surface of the sea. As the sun made it very warm, it changed into steam. The steam left the sea and went up into the air, and it did not carry any salt with it. It had left the salt in the sea.
The steam from the raindrop moved with the warm air towards the north. On the way the warm air met some cold air. The cold air pushed the warm air high above the ground.
The warm air became cool when it went up, and the steam in it changed into very small drops of water again. There were millions and millions of these small drops in the cloud. The small drops came together into bigger and bigger drops. Our raindrop was one of them. Now the drop became so big that it was too heavy to stay in the cloud, and it fell to the ground. In this way the water of our raindrop, started traveling to the sea again.
