Presentation Transcript

  1. Aquifer Geology and Geography Permeable materials such as sandstone, limestone and layers of sand and gravel

  2. Recharge Zone • Ground surface where water enters an aquifer • Dependent on permeability

  3. Springs and Wells • Movement determined by the slope of the water table • If the water table reaches the Earth’s surface water will flow out of the ground (Spring) • Water table higher than the Earth’s surface lakes will form.

  4. Artesian Well • Water flows from a crack in the cap rock of an aquifer. http://www.bartleby.com/images/A4images/A4artwel.jpg

  5. Hot Springs • one form of an artesian well http://www.personal.engin.umich.edu/~yeq/images/YellowStone%201/Mammoth%20Hot%20Springs%201.jpg

  6. Wells • A human made hole that is deeper than the level of the water table http://mainegov-images.informe.org/doc/nrimc/mgs/sites-1999/oct99-1.gif

  7. Cave Formations • The underground erosion of limestone • Caused by carbonic acid

  8. Deposition • Deposits of calcium carbonate

  9. Stalactites • Stalactites-form from the ceiling http://www.goodearthgraphics.com/virtcave/staltite/stal1.jpg

  10. Stalagmites • Stalagmites-form from dripping water http://www.dudleycc.pwp.blueyonder.co.uk/stalagmites.jpg

  11. Dripstone Column http://science.nature.nps.gov/im/images/cavecol1.jpg

  12. Sinkholes • When the water table is lower than the level of a cave • Results in the roof collapsing
