Hello, my name is Drippy, and I am a tiny drop of water. I live in the big blue ocean near Busan with millions of other drops. Every day, I splash and play in the waves with my friends.
One hot summer morning, the sun shone down on the sea. Its warm light made me feel lighter and lighter. Then I began to rise slowly into the sky! This change is called evaporation. I turned into water vapor, a gas that you cannot see.
High up in the sky, the air was very cold. The cold air changed me back into a tiny drop of water. I held hands with many other drops, and together we made a white cloud. This change is called condensation.
Our cloud grew bigger and darker as more drops joined us. Soon we were too heavy to stay up in the air. Down, down, down we fell as rain! Water that falls from the sky is called precipitation. In winter, it can fall as snow, too.
I landed on a green mountain and ran down into a stream. The stream joined a wide river that flowed all the way to the sea. At last, I was back home in the ocean.
Soon the warm sun will lift me up again, and my trip will start over. Round and round I go, from the sea to the sky and back again. This never-ending trip is called the water cycle!
