GEOL 1425 1st Edition Lecture 19Outline of Last LectureI. About the climate systemII. Components of the climate systemIII. Climate models and their limitationsOutline of Current LectureI. About the hydrological cycleII. Flows and reservoirsIII. Groundwater Current Lecture—the Hydrologic Cycle and GroundwaterI. About the hydrological cycle—important for climate system and our system. Hydrology: the study of movement and characteristics of groundwaterII. Flows and reservoirsa. Flows- water flows into things and then flows out of things… b. Reservoir- any staging spot where water is stored in or on Earth. Largest are oceans. Groundwater more important in storage than surface water. Largest supply of water after oceans and frozen water, but lots isn’t usable/drinkable.c. Hydrologic cycle: water cyclical movement of water between reservoirs. The sun drives the cycle in terms of evaporations, ice and snow melting, resulting insurface runoff or movement into the groundwater. Components: Precipitation- rain, hail, snow sleet… clouds and water droplets and rain.Mostly occurs mostly over the oceans; most of the precipitate into the oceans will flow back into the oceansInfiltration and runoff- how well a soil will absorb water. Infiltrate mostly through soil and occasionally through rock. Soil is developed by rock from weathering though. Evaporation, transportation (loss of water from flora), and sublimation (water going from one phase to another—water to gass)Groundwater flow- groundwater takes longer to move from cycle than runoff waterThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.d. Hydrology and climatei. Monsoon-type climates—water supply sinks during dry season and thenquickly replenished reservoirs during monsoon seasonii. Ocean-land relationships with onshore breezes and offshore breezesIII. Groundwatera. Aquifer—beds that store and transmit groundwater in sufficient quantity to supply wells. Can recharge streams. b. Sedimentary rocks are best for groundwater storagec. Porosity and permeabilityd. Groundwater tablee. Vados zone- above the saturated
