DESCRIPTION
Atmospheric Processes – The Water (Hydrological) Cycle Precipitation – ◦ Water has condensed to the point that the air in the atmosphere cannot hold it anymore. ◦ Clouds get heavy & water falls back to the earth in the form of rain, hail, sleet or snow Collection/Infiltration/Runoff – ◦ Water falls back to earth from the atmosphere as precipitation ◦ May fall into oceans, lakes or rivers or on land “Collection” ◦ On land, it will either soak into the earth or become part of the groundwater that plants & animals use to drink “Infiltration” ◦ May run over the soil & collect in oceans, lakes or rivers where the cycle starts all over again “Runoff”TRANSCRIPT

Atmospheric Processes• Atmospheric processes –
the interaction of Earth’s with land & water (oceans)• How much of Earth’s
surface is covered by water (oceans)?• Oceans exchange & transport heat & moisture in the
atmosphere

Atmospheric Processes – The Water (Hydrological) CycleEvaporation –
◦ The sun heats up water in rivers, lakes or the ocean ◦ Turns it into vapor or steam◦ Water vapor or steam leaves rivers, lakes, or oceans & goes into
the atmosphere
Transpiration – ◦ Plants lose water out of their leaves◦ Transpiration puts water vapor back up into the atmosphere.
So…you might ask…do plants sweat? Well, sort of.... people perspire (sweat) and plants transpire.
Condensation –◦ Water vapor in the atmosphere gets cold & changes back into
liquid, forming clouds, in the atmosphere

Atmospheric Processes – The Water (Hydrological) CyclePrecipitation –
◦ Water has condensed to the point that the air in the atmosphere cannot hold it anymore.
◦ Clouds get heavy & water falls back to the earth in the form of rain, hail, sleet or snow
Collection/Infiltration/Runoff –◦ Water falls back to earth from the atmosphere as precipitation◦ May fall into oceans, lakes or rivers or on land
“Collection”◦ On land, it will either soak into the earth or become part of the
groundwater that plants & animals use to drink “Infiltration”
◦ May run over the soil & collect in oceans, lakes or rivers where the cycle starts all over again “Runoff”

A. Groundwater stored in the pores and spaces in the ground below you…also known as an “aquifer”.
B. Your great-grandmother’s spitC. Water evaporated from Tempe Town LakeD. All of the above
A: D. All of the above!
