what is the process of changing a liquid to a vapor?
what is the general name for water in any form falling from clouds?
what is the greenhouse effect?
the trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

the process by which water in the plants is transferred as water vapor to the atmosphere?
Transpiration is the process by which plants lose water out of their leaves (kind of like when people perspire).
