Water and Sunlight is the most important key for the living being to live on earth. But due to sunlight the water forms into vapour and vapourized to sky. But why it does not moves to space. In following reason we have discussed about the topic.
Temperature and Speed: Due to sunlight high temperature generates and the water forms into vapour. As the temperature of vapour is hot, it moves to upper atmospheric level. But due to the gravity the speed is not expected.
Condensation and Precipitation: Water Vapour does not condense and precipitate out of atmosphere easily at high temperature. Due to raining it does not have any chance to store in atmosphere. After forming cloud it includes on rain cycle.
Hydrological Cycle: This is also known as water cycle. The process of vapouring to forming cloud to rain.
Atmospheric Pressure: Due to pressure of atmosphere the vapoured water completes the journey to formation of cloud. Because the hot air is less dense than cold. So, after vapourising the vapoured hot vapour moves to upper surface of atmosphere and cold air replace its space. But due to this pressure and gravity it is unable to reach space.
So, in conclusion we can say that it is not possible to complete the journey from earth to space by water vapour. Follow for more and don't stop your imagination. To be continued..
