The document discusses key concepts related to water vapor and humidity in the atmosphere including relative humidity, dew point, transpiration, cloud formation, thermal convection, and the role of meteorologists. It defines water vapor, humidity, relative humidity, dew point, and explains how transpiration, cloud formation, and thermal convection occur. It also defines meteorologists as scientists who study the atmosphere and weather.
13. thermal – a rising air current caused by heating the Earth’s surface (radiation)
14. 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
15. convection – when relatively warm air is raised into the atmosphere, often cooling and forming clouds
16. meteorologist – a scientist who deals with the atmosphere, including weather and climate
