Earth Science June 16, 2019 admin Infiltration Process by which precipitation that has fallen on land trickles into the ground. Zone of saturation Region below the Earth’s surface in which groundwater fills all the pores of material. Water table Upper boundary of the zone of saturation Zone of aeration Area above water table. Materials are moist, but not saturated. Permeability Tendency of material to let water pass through it. Aquifers Water flows through permeable sediment and rock into large pore spaces. Aquicludes Impermeable layers that are barriers to groundwater flow. Springs Natural discharges of groundwater. Hot springs Springs with temperatures higher than the human body. Geyers Explosive hot springs. Cave Natural underground opening with a connection to the surface. Sinkhole A depression in the ground caused by the collapse of a cave Karst topography Limestone regions that have sinkholes and disappearing streams. Stalacite Hangs from the cave’s ceiling Stalagmites Grow from cave floor Drawdown Difference between original water table and water level in a pumped well. Recharge Water from precipitation replenishes the water content of an aquifer. Artesian well An aquifer that contains water under pressure Related posts: BoB Flash Cards-2 Geology test 2 Plant Pathology: Lab Exam CDC Integrative Management of Invasive Insect Pests: Quiz 2 BEI Test Environmental Science Exam 1 ESRM Midterm 2 ENVS4000 EAS 205 #2
