Unit 3 pp #3 6th grade

  1. 1. Section 1 Florida's Land Resources<br />Chapter 15<br />The Natural Landscape<br /><ul><li>Florida’s land surface is about 36,000,000 acres.
  2. 2. Florida’s major ecological communities include woodland forests, dry prairies, wetlands, and beaches.
  3. 3. Woodland forests are located primarily in northern Florida, and dry prairies are found mainly in central Florida. Wetlands include the Everglades in southern Florida.</li></li></ul><li>Chapter 15<br />Section 1 Florida's Land Resources<br />
  4. 4. Section 2 Florida's Freshwater Resources<br />Chapter 15<br />Groundwater<br /><ul><li>Groundwater is one of Florida’s most valuable resources. It’s stored in formations called aquifers.
  5. 5. An aquifer is a body of rock or sediment that stores groundwater and allows the flow of groundwater.
  6. 6. Aquifers provide nearly 90% of Florida’s drinking water.</li></li></ul><li>Section 2 Florida's Freshwater Resources<br />Chapter 15<br />Groundwater<br />
  7. 7. Section 2 Florida's Freshwater Resources<br />Chapter 15<br />Groundwater, continued<br /><ul><li>The Floridan Aquifer underlies most of Florida and parts of three other states. It is one of the largest aquifers in the world.
  8. 8. Water from aquifers can rise to the surface to form springs.
  9. 9. Every day, nearly 9 billion gallons of water flows from more than 700 springs in Florida.</li></li></ul><li>Section 2 Florida's Freshwater Resources<br />Chapter 15<br />Groundwater, continued<br /><ul><li>Wells and Groundwater Groundwater is usually pumped to the surface from wells drilled in Earth’s crust.
  10. 10. As it flows down through rocks and sediments in an aquifer, groundwater becomes filtered and purified.
  11. 11. Therefore, deep wells can provide water that is free of pollutants.</li></li></ul><li>Section 2 Florida's Freshwater Resources<br />Chapter 15<br />Groundwater, continued<br /><ul><li>Threats to Florida’s Groundwater include overwithdrawal, saltwater intrusion, and pollution.
  12. 12. Overwithdrawal occurs when water is removed from an aquifer faster than it can be replaced.
  13. 13. In extreme cases, overwithdrawal causes part of the aquifer to collapse, forming a sinkhole. It can also cause springs and streams to dry up.</li></li></ul><li>Section 2 Florida's Freshwater Resources<br />Chapter 15<br />Groundwater, continued<br /><ul><li>Overwithdrawal in coastal aquifers can cause ocean water to flow into the aquifer, in a process called saltwater intrusion.
  14. 14. Since nearly 90% of Floridians live near the coast, saltwater intrusion is a problem in many aquifers.
  15. 15. Pollution from agricultural and lawn care chemicals and leaking underground fuel tanks also threatens groundwater.</li></li></ul><li>Section3 Water Underground<br />Chapter 16<br />The Location of Groundwater<br /><ul><li>Surface water seeps underground into the soil and rock. The water passes through an area called the zone of aeration and collects in an area called the zone of saturation.
  16. 16. The boundary between the two zones is known as the water table.</li></li></ul><li>Section3 Water Underground<br />Chapter 16<br />
  17. 17. Section3 Water Underground<br />Chapter 16<br />Underground Erosion and Deposition<br /><ul><li>Cave Formation Although caves are formed by erosion, they also show signs of deposition. Water that drips from a crack in a cave’s ceiling leaves behind deposits of calcium carbonate.
  18. 18. Sinkholes When the water table is lower than the level of a cave, the cave is no longer supported by the water underneath. The roof of the cave can then collapse, which leaves a circular depression called a sinkhole.</li>
