Question

Evaporation Humidity Transpiration Precipitation is caused by two forces: (1) increasing water vapor and (2) decreasing air temperatures to its dew point. Increasing water vapor happens in a variety of ways. The dominant source of atmospheric water vapor is evaporation. As a warm air mass moves across a cooler body of water, liquid water evaporates into gaseous water increasing the air mass's humidity, or the amount of water in an air mass. Secondly, when plants absorb water from their roots, the water Is carried through their vascular system and is released to the atmosphere through small pores in their leaves, a process known as transpiration. Condensation As air masses cool, water vapor condenses to liquid water, forming clouds. Eventually, this water falls back to Earth as precipitation (as rain, snow, or ice), when the atmosphere becomes saturated with water vapor. Dew point is the temperature at which water vapor condenses into liquid water at the same rate it evaporates. At temperatures below the dew point, water in the atmosphere condenses and precipitates; while at temperatures above the dew point, atmospheric liquid water vaporizes into As warm air moves across a cool ocean, do the following phenomena increase, decrease or remain the same? Evaporation___ Humidity___ Transpiration___ As air rises (Fig. 10), do the following phenomena increase, decrease or remain the same?
