Water vapor is a relatively common atmospheric constituent, present even in the solar atmosphere as well as every planet in the Solar System and many astronomical objects including natural satellites, comets and even large asteroids.
Where is vapor found?
Atmospheric water vapor is found near the earth’s surface , and may condense into small liquid droplets and form meteorological phenomena, such as fog, mist, and haar. Mercury-vapor lamps and sodium vapor lamps produce light from atoms in excited states.
Where does most of our water vapor come from?
About 90 percent of water in the atmosphere is produced by evaporation from water bodies , while the other 10 percent comes from transpiration from plants. There is always water in the atmosphere.
What are examples of water vapor?
An example of water vapor is the floating mist above a pot of boiling water . Water in the form of a gas; steam. Water in its gaseous state, especially in the atmosphere and at a temperature below the boiling point. Water vapor in the atmosphere serves as the raw material for cloud and rain formation.
Is water vapor found everywhere?
Introduction. Water is a compound of hydrogen and oxygen having the chemical formula H 2 O and is found everywhere on the surface of Earth , even in deserts and high in the atmosphere. ... Although water vapor is a trace gas in Earth’s atmosphere, making up only about .
Can we see water vapor?
Although you can’t see water vapor, you can feel it . ... On humid days, there’s a lot of water vapor in the air. You feel hotter and stickier than on less-humid days because the water vapor is slowing down the evaporation of sweat. (As sweat evaporates, your skin feels cooler.)
Why can we see water vapor?
Unlike clouds, fog, or mist which are simply suspended particles of liquid water in the air, water vapour itself cannot be seen because it is in gaseous form . Water vapour in the atmosphere is often below its boiling point. ... Steam often has droplets of water, which is what is seen water is boiling.
Which is a better source of water vapor?
As the temperature of the atmosphere rises, more water is evaporated from ground storage ( rivers, oceans, reservoirs , soil). Because the air is warmer, the relative humidity can be higher (in essence, the air is able to ‘hold’ more water when its warmer), leading to more water vapor in the atmosphere.
How long does water vapor stay in the atmosphere?
Water vapour will generally stay in the atmosphere for days (before precipitating out) while other greenhouse gases, such as carbon dioxide or methane, will stay in the atmosphere for a much longer period of time (ranging from years to centuries) thus contributing to warming for an extended period of time.
Where is most of the water on Earth stored?
Over 68 percent of the fresh water on Earth is found in icecaps and glaciers , and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
What is water vapor in simple terms?
: water in a vaporous form especially when below boiling temperature and diffused (as in the atmosphere)
Is water vapor matter Yes or no?
Water vapor is water in its gaseous state -instead of liquid or solid (ice). Water vapor is totally invisible. If you see a cloud, fog, or mist, these are all liquid water, not water vapor. Water vapor is extremely important to the weather and climate.
Is water vapor the same as water?
Water vapor just means the gas form of water . Water is a molecule, not specifically a liquid.
Is there more water in the sky or ocean?
| Water source Water volume, in cubic miles Percent of total water | Oceans , Seas, & Bays 321,000,000 96.54 | Ice caps, Glaciers, & Permanent Snow 5,773,000 1.74 | Groundwater 5,614,000 1.69 | Fresh 2,526,000 0.76 |

What is the process called when water from ice or snow turns directly into vapor without melting?
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.
