Unformatted text preview: ATMOSPHERIC MOISTURE The proportional distribution of water Nearly all of the Earth's water is contained in the world ocean. Fresh surface and soil water make up only a small fraction of the total volume of global water. Ice sheets and glaciers are the second largest reservoir of water. The Hydrologic Cycle Circulation of water in the atmosphere. It is a continuous cycle of evaporation, condensation, and precipitation. Water is continually transferred from one state to another as a liquid, vapor, or solid. The Hydrologic Cycle Precipitation has three fates: 1. 2. 3. It can evaporate and return to the atmosphere as vapor It can soak into the soil and into the surface rock layers below. Subsurface water emerges from below to feed rivers, lakes, and ocean margins. Precipitation can run off land into streams and rivers that eventually carry it to the ocean or lakes...aka Runoff. The Hydrologic Cycle
Water from the oceans and from land surfaces evaporates, changing state from liquid to vapor and entering the atmosphere. Once in the atmosph...
