Chapter 10, Lesson 4 Water Vapor and Humidity water vapor humidity relative humidity transpiration cloud formation thermal convection meteorologist 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 transpiration –watery vapor passed through a membrane or pores in a plant cloud formation – the way clouds form cloud formation – the way clouds form cloud formation – the way clouds form cloud formation – the way clouds form cloud formation – the way clouds form thermal – a rising air current caused by heating the Earth’s surface (radiation) thermal – heated air that rises thermals help these birds to soar, they help gliders soar, too. They push air into the atmosphere, that cools and forms clouds convection – when relatively warm air is raised into the atmosphere, often cooling and forming clouds meteorologist – a scientist who deals with the atmosphere, including weather and climate
