Document Summary
Gg101 chapter 7 notes- water and atmospheric measure. Pure water is colourless, odouress and tasteless; yet, because it is a solvent (dissolves solids), pure water rarely occurs in nature. Constitutes nearly 70% of our body mass; we can only survive 2-3 days without water. Earth"s hydrosphere contains about 1. 36cu. kilometers of water: most water came from icy comets and hydrogen/oxygen laden debris. Outgassing: a continuing process by which water and water vapes emerge from layers deep within and below the crust. In the early atmosphere, massive quantities of outgassed water vapes condense and then fell to earth in torrential rains. For water to remain in earth"s surface, land temp"s had to stay below 100 degrees c. Most water that was originally on earth is still here today. Water is lost when it dissociates into hydrogen and oxygen and the hydrogen escapes. Eustacy: describes global sea-level condition; volume in the oceans.
