GSCI 1051 Lecture Notes - Lecture 9: Evapotranspiration, Water Cycle, Hydrosphere
Document Summary
Metamorphic rock mineralogy- depends on protolith mineralogy, temperature, and pressure: rocks with one mineral often form rocks containing the same mineral. Only change is texture: in rocks containing multiple minerals, new ones often form. New england rocks indicate mountain building occurred here: metamorphic rocks return to the surface when they are exhumed by uplift, collaps, and erosion. Groundwater: total mass of water is the hydrosphere. Volume is 1. 4x10^17 0. 023% total mass: water cycle- water constantly circulating and changing phases. Sublimation- ice becomes gas, unused ice cubes get smaller this way. Evapotranspiration- evaporation from leaves during respiration: groundwater. Occurs in pores or cracks below ground. a major source of drinking and irrigation water.
