This illustration shows us the water cycle, which is the continuous movement of water on, above the below the surface of the Earth. On scientific language this cycle calls photosynthesis. The first step of photosynthesis starts in ocean . Interesting fact is about the ocean contributes about 60% of total water vapour in air. This is means that when ocean condensing vaporized water , it turns into a cloud. We all know that in certain seasons the cloud make precipitation, or rain. Now this water drops into the depressions, and replenishes lakes, and if the water falls on the mountain peak, the water is gonna creating to snow, because in mountain high ground the temperature is low. Other water or the water that created after melting the snow, going to through the inside of the mountain straight into the ocean or seas, penetrating through the earth and different types of minerals, water becomes salty. This is the cycle of water.
