Chapter 7: Water and Atmospheric Moisture I. Water on Earth I.a. Outgrassing : continuing process by which water and water vapor emerge from layers deep within and below the crust I.a.i. Still happening, examples: volcanic eruptions, geysers, and seepage I.a. Worldwide Equilibrium I.a.i. Water lost when it dissociates into hydrogen and oxygen--> hydrogen escapes Earth's gravity to space or breaks down to form new compounds I.a.i. Steady-state equilibrium due to water continuously seeping onto surface from crust I.a.i. Eustasy : describes global sea-level condition, relates to water volume in oceans (not changes in overall quantity of water on planet) I.a.i. Glacio-eustatic factors: amount of water stored in glaciers and ice sheets that varies I.a.i.1. Cooler times: more water bound up in glaciers (high latitudes, mountains) and ice sheets (Greenland, Antarctica)--> lower sea level I.a.i.1. Warmer times: less water stored as ice--> rise in sea level I.a.i. Isostasy : refers to actual vertical physical movement in landmasses
