GEO 105 Lecture 11: GEO 105 Chapter 6 Part 1: Atmospheric Moisture
Document Summary
Net positive charge on one side and a negative side on the other. Electrical polarity causes the surface of liquid water to bead, hydrogen bonds are stronger than the (cid:271)ug"s weight. Adhesion describes how water sticks to many other substances. Caused by a combination of surface tension and adhesion. Plants make use of capillarity to bring water to their leaves. Evaporation and transpiration from the surface is how water vapor is put into the air. The warmer the water, the easier it is to evaporate. The equilibrium condition when the rate of evaporation is equal to the rate of condensation is called saturation. This is when the relative humidity is 100% The change of phase of water is an important energy sources. Water vapor is the source of all clouds and precipitation. The amount of water in the atmosphere determines the rate of evaporation. Water vapor is the most important greenhouse gas.
