  1. Physiographic Regions of Georgia EQ: What are the characteristics of Georgia’s five geographic regions?

  2. Region • An area on Earth’s surface that is defined by certain unifying characteristics (cultural, physical, or human)

  3. Appalachian Plateau

  4. Plateau

  5. 300 square miles NW corner (TAG-TN,AL,GA Corner) of Georgia Part of Appalachian Mountains 800-2000 feet Size/Location Elevation

  6. Landforms • Broad flat topped mountains separated by ridges of limestone • Limestone caves, deep canyons, interesting rock formations, waterfalls

  7. Soil/Rocks, minerals • sandstone, shale, limestone

  8. Resources/Crops • Appalachian Oak Forests cover most of it. • pastures • Coal • the only source of coal in Georgia

  9. Cities/Places of Interest • Sand Mountain • Lookout Mountain • Long narrow valley between these mts. • Cloudland Canyon • Chickamauga-civil war battle site

  10. Ridge and Valley

  11. Ridge and Valley

  12. most of NW Georgia Part of Appalachian Mountains 700-1600 feet Size/Location Elevation

  13. Landforms • long, parallel ridges • wide rolling valleys

  14. Soil/Rocks, minerals • sedimentary rock • sandstone ridges • limestone and shale valleys

  15. Resources/Crops • Forests, pastures • Apple orchards, wheat, cotton, hardwoods, pines, • 4% of Georgia’s farmland • timber

  16. Cities/Places of Interest • Taylor Ridge, Pigeon Mountain • Dalton • Carpet industry – more than 70 carpet manufacturing plants

  17. Blue Ridge

  18. Blue Ridge

  19. most of NE Georgia 2000 square miles Part of Appalachian Mountains 1600-4800 feet Size/Location Elevation

  20. Landforms • highest mountains in Appalachian highlands • Rivers begin here. • steep slopes • waterfalls

  21. Soil/Rocks, minerals • clay, sand • erosion • High precipitation – provides water for the entire state

  22. Resources/Crops • Hardwood forests • apples • Small vegetable farms

  23. Cities/Places of Interest • Chattahoochee National Forest • Brasstown Bald (treeless on top) 4,784 ft. • Amicalola falls • Tallulah Gorge • Helen

  24. Other Features • Springer Mountain • start of the Appalachian Trail which stretches from Georgia to Maine (2,144 miles)

  25. Piedmont “foot of the mountain”

  26. Piedmont

  27. 30% of state between the Coastal Plain and the mountains 500-1700 feet Size/Location Elevation

  28. Landforms • Gently, sloping hills, flatlands • valleys • many streams and rivers • ravines

  29. Soil/Rocks, minerals • red clay, sandy loam • fertile soil • bedrock • large areas of solid rock just below the earth’s surface • often exposed where soil has washed away • granite, gneiss, marble

  30. Resources/Crops • oak-hickory-pine forests • marble, granite • cotton, soybeans, wheat, poultry, cattle

  31. Cities/Places of Interest • Athens • Atlanta • Milledgeville • Six Flags • Zoo Atlanta • Stone Mountain

  32. Other features • 60% of Georgia’s population lives here. • Chattahoochee, Flint, Ocmulgee, Oconee Rivers

  33. Coastal Plain

  34. Coastal Plain

  35. 60% of state lower half of the state 0-400 feet Size/LocationElevation

  36. Landforms • Two parts • Inner Coastal Plain • Outer Coastal Plain • gentle slopes • wide, deep, slow rivers

  37. Soil/Rocks, Minerals • Limestone, sand, clay • Outer coastal plain -- poorly drained • Inner Coastal plain -- fertile soil, underground water

  38. Resources/Crops • Outer Coastal Plain • wetlands (freshwater swamps, salt marshes) • used for pasture and timber • shrimp and fish • naval stores and pulp production • Barrier Islands • Inner • grows most of Georgia’s agricultural products • crops such as peanuts, cotton, Vidalia onions, corn, soybeans, peaches, pecans

  39. Cities/Places of Interest • Savannah (GA’s 1st settlement), Columbus, Macon, Augusta, Albany, Valdosta • Deep water ports (Savannah and Brunswick) • Okefenokee Swamp – largest freshwater wetlandin N.America

  40. Other features • once covered by ocean • Barrier Islands • protect mainland by blocking sand, wind, water that might cause erosion • tourism, recreation, wildlife sanctuaries (2/3 wilderness) • Jekyll Island (state park) • Cumberland Island (national seashore)

  41. Fall Line • Point at which hilly or mountainous lands meet the coastal plain • Columbus, Macon, Augusta • Waterfalls provide a power source
