6.3 Water Beneath the Surface of the Earth:  6.3 Water Beneath the Surface of the Earth Cave Facts:  Cave Facts The world's deepest cave goes down 5,256 feet (1,602 meters) and is located in Haute Savoie, France. Mammouth Cave in Kentucky is the world's longest cave system, traveling for over 340 miles. 6.3 Water Beneath the Surface of the Earth:   Most water seeps downward into the zone of saturation.  Zone of saturation - where water fills all of the open spaces. 6.3 Water Beneath the Surface of the Earth Slide4:   Movement • Porosity • Permeability - The percentage of pore spaces - Determines how much groundwater can be stored Ability to transmit water through connected pore spaces Soils with low permeability readily form ponds. Slide5:   A spring forms where the water table intersects the ground surface. Geyser Eruption Cycle:  Geyser Eruption Cycle • Intermittent hot springs  Geysers • Water turns to steam and erupts. Slide7:   Well - hole bored into the zone of saturation. • Artesian well - groundwater rises on its own under pressure. Cone of Depression:  Cone of Depression A cone of depression may form around a well… it may eventually be left dry. Slide9:   Overuse and contamination threatens groundwater supplies in some areas. • We should treat water as a nonrenewable resource Groundwater Contamination:  Groundwater Contamination Your House Your neighbors house The water traveled 100 meters before it reaches the well, but it moves too quickly over the limestone to be purified! Ugh! As discharge from the septic tank permeates through the permeable sandstone it is purified. Slide11:  Cavern – naturally formed underground chamber Groundwater erodes away rocks (usually) limestone Dissolving of Groundwater Creates Caverns Dissolving of Groundwater Creates Caverns:  Dissolving of Groundwater Creates Caverns Dripstone Features- form from dripping calcite Stalactite (ceiling) Stalagmite (floor) What is the difference between a cave and a cavern? :  What is the difference between a cave and a cavern? Cave - any cavity in the ground large enough that some portion of it will not receive direct sunlight Cavern - A type of cave with the ability to grow dripstone features Slide14:  Dissolving of Groundwater Creates Caverns Who says there isn’t anything to do in Indiana? Looking for a roadtrip for you and your friends? Be a Goonie… :  Who says there isn’t anything to do in Indiana? Looking for a roadtrip for you and your friends? Be a Goonie… Marengo Cave in Southern Indiana Walk through the caves Put on a helmet and explore the caves by crawling through passages Make a campfire and stay in their cabins Slide16:  The Discovery of Marengo Cave Blanche Heistand, age 15 and her brother Orris Heistand, age 11 September 6, 1883 On September 6, 1883, fifteen-year-old Blanche Hiestand, a cook at Marengo Academy, overheard some of the schoolboys making plans to explore a deep sinkhole located in a graveyard near the school. Blanche decided to beat them to it! She excitedly ran home after work and recruited her eleven-year-old brother, Orris. They grabbed some candles and snuck out of the house. Blanche and Orris quickly hiked up the hill past the cemetery by the church. They found the sinkhole, surrounded by a grove of trees, and climbed to the bottom. Together they Blanche and Orris crawled down the steep, slippery slope. They found themselves in a large chamber that appeared to continue in several directions. They heard water falling and saw formations in the distance. Having only candles to light their path the pair decided to turn back. Blanche and Orris safely reached the top. The original land owner was notified of the cave's discovery a few days later and the cave was immediately opened to the public for tours. Slide17:   Formed by dissolving rock at, or near, Earth's surface • Sinkholes— form when bedrock dissolves and caverns collapse.  Common feature Sinkhole Formation:  Sinkhole Formation
