water vapor - water in its gas form is water vapor. If you can see it, it’s
not really water vapor!

humidity – the level of moisture in the air; the amount of water
vapor in the air

relative humidity – is when you compare how much water vapor
is in the air to how much it COULD hold

dew point – point when the air is completely saturated with
moisture and can hold no more.

transpiration –watery vapor passed through a membrane or
pores in a plant

thermal – a rising air current caused by heating the Earth’s
surface (radiation)
![Page 14: Chapter 10, Lesson 4 Water Vapor and Humidity](https://reader034.fdocuments.in/reader034/viewer/2022050821/56816519550346895dd7975d/html5/thumbnails/14.jpg)
thermal – heated air that risesthermals help these birds to soar,they help gliders soar, too. They
push air into the atmosphere, that cools and forms clouds
![Page 15: Chapter 10, Lesson 4 Water Vapor and Humidity](https://reader034.fdocuments.in/reader034/viewer/2022050821/56816519550346895dd7975d/html5/thumbnails/15.jpg)
convection – when relatively warm air is raised into the
atmosphere, often cooling and forming clouds
