WATER RECYCLE
Oceans are big masses of water. This water does not just stand still but keeps its cycle in the nature. Having a significant importance in our lives, oceans can also serve us as a resource for drinking water. At first, water evaporates from these oceans by the warming effects of the sun. Then, this vapor turns into clouds. When the clouds meet a cold layer in the atmosphere, the vapor is cooled and falls back on Earth as rain via precipitation. This event usually occurs around mountain area. The rain is usually stored as ice and snow on the mountains, and some of this rain runs down into the valleys as rivers and streams. Meanwhile, some of this water is absorbed by the ground and it goes underground. Later, the water finds its way to the surface and streams into rivers and join them on their way back to the oceans. Eventually, the water reaches to the oceans to restart its journey within the water cycle. Finally, the cycle starts all over again.
