where is most the water in the atmosphere contained
within the troposphere
What is a source of moisture within the atmosphere
Evaporation from surface: requires energy to supply latent heat of evaporation – sunlight, conduction from surface (cools surface).
Evaporation of precipitation falling from above: latent heat supplied by cooling of air
what is a sink of moisture in the atmosphere
Precipitation: rain, snow, hail,…
Condensation at the surface: dew, frost
