Aquifer Flash Cardsaquifer - correct answer An aquifer is a pool of groundwater that is large enough to be an economic recourse exists in sediment Ways to clean Aquifers - correct answer -Pump water out of aquifer on downhill side Pump clean water into the aquifer on the uphill side -Close off Aquifer from the world when it becomes too dangerous -Stop the pollution at the source. Find the source and shut it down. -Dig a deeper well (very hard to contaminate deep aquifer because the soil acts as a filter. However, it is very difficult to clean deep aquifers because it is very expensive) Confined Aquifer - correct answer A confined aquifer is an aquifer that is sandwiched between two layers of rock or clay. It lets water in but doesn't let the water out (deeper) Unconfined Aquifer - correct answer An aquifer that has no confining layer. NO sandwiching. This aquifer is less deep than a confined layer. (Shallower: water doesn't stay well) Artesian Aquifer - correct answer An Aquifer that needs no pump: Water comes from such a height that gravity acts as its pump Aquitard - correct answer A rock like granite or clay that doesn't let the water out or in, when water is stuck between two aquitards, it acts as a tunnel. Water table - correct answer The highest level of the water saturating the water beneath the ground -Sizes of sediment - correct answer a. Sand (5) b. Gravel (3) c. Clay (7) d. Boulder (1) e. Cobblestone (2) f. Pebble (4) g. Silt (6) Porosity: - correct answer The percentage of open viod space in the surface material; it is expressed as a percent Permeability - correct answer How readily a fluid can flow through a material; often referred to as connected pore space. A rock can be porous but not permeable All permeable rocks are porous Clay is impermeable (aquitard) Largest Aquifer in USA - correct answer The Ogallala aquifer What 8 states does the Ogallala Aquifer go through? - correct answer Texas, Nebraska, Oklahoma, Kansas, New Mexico, Wyoming, South Dakota, Colorado KNOWNCTS What are the two things a rock must be to make up an aquifer - correct answer Permeable and porous. (Not all rocks that are permeable are porous) Best material for Aquifers - correct answer Gravel, Sand Karst includes what type of rock - correct answer limestone
