Water Vapor

Water vapor or water vapour (see spelling differences), also aqueous vapor, is the gas phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Unlike other forms of water, water vapor is invisible. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation. It is lighter than air and triggers convection currents that can lead to clouds.

Water vapor is a potent greenhouse gas along with other gases such as carbon dioxide and methane.

Famous quotes containing the word water:

    We wished our two souls
    might return like gulls
    to the rock. In the end,
    the water was too cold for us.
