The percentage of water vapour present in the earth's atmosphere is variable, it keeps changing from place to place as well as time to time. In rainy season it is very high but in the dry season it is very low.
Yes, in the atmosphere water vapour falls as rain.
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
Stomatastomata is a pour found on the leaf or stem of a plant which opens and closes to release water vapour and gases into the atmosphere.
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
Yes, it evaporates, becoming water vapour which moves up into the atmosphere to form clouds.
It varies. There is no single percentage value
What happened to all the water vapour in the early atmosphere
Yes, in the atmosphere water vapour falls as rain.
it becomes water vapour in the atmosphere.
I'm guessing water vapour
ionosphere
Humidity is the amount of water vapour in the atmosphere
transpiration
Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
The most variable abundance in the atmosphere is Water Vapour and Ozone
As the earth cooled, water vapour in the atmosphere condensed to a liquid (water) and fell to the earth as rain the make the oceans.
