Document Summary
Because atmosphere press decreases with altitude, air moving upwards expands -> it gets colder. + when colder air mass slides under the warmer air mass. + can be buoyed upwards due to unequal heating at the surface. + follows a physical barrier (i. e mountain range) Water can exist in three states - solid (ice), liquid (water), and gas (water vapor) ***draw diagram of latent heat flow: = energy i. e: sublimation: + old ice cubes begin to shrink (smaller) when stored for a long time because of the constant circulation of cold, dry air in the freezer. + reserve process: from water vapor to ice (solid water) causes frost on a car windshield on a winter"s night. The earth"s water in all its forms. Majority of water occurs as ocean saltwater (~ 98%) Of the remaining water (only 2. 8% of fresh water) the majority is accounted for by glaciers and ice sheets (both 2. 15%) and groundwater.
