Universal Solvent
Gaseous water forming liquid water (i.e. clouds) in the atmosphere.
condensation

photosynthesis or carbon fixation
The current atmospheric conditions is known as....
weather
This property of water allows water to stick to itself.
cohesion
Contact lens design relies on water's ______ so a thin, stable tear film clings to the lens surface, keeping the eye moist and comfortable
adhesion
Water lost by plants to the atmosphere, often during photosynthesis.

The two primary measures of climate are ____ & ____. Think, for example what two conditions of the atmosphere make a desert different from a forest.
temperature and precipitation
A change in this property of water occurs when water changes from liquid to solid, resulting in ice floating.
Density

temperature
When water moves from the surface of the Earth, such as from a river or lake, down into the soil and rock layers beneath.
infiltration
