  • Also called Cumberland Plateau (Lookout Mountain and Sand Mountain separated by limestone ridges)
  • Limestone, shale, and sandstone soils
Ridge and Valley
  • Between Blue Ridge Mountains and Appalachian Plateauu
  • Low open valleys parallel to narrow ridges
  • Elevations ranges from 700 to 1600 feet above sea level
  • Forests and pastures dominate the region
  • Limestone and clay soils in the valley
  • Shale and sandstone on the ridges
Blue Ridge
  • Northeastern part of state
  • Contains state’s highest and largest group of mountains
  • Brasstown Bald, Georgia highest mountain is here
  • Mountains provide much precipitation (water) for the state
  • Sandy loam and clay soils
  • Hardwood forests, vegetable farming, and apples
 Piedmont Plateau

  • Gently sloping hills in north, flatlands in the south
  • Hardwood timber, pine, and agriculture
  • Red clay and granite base
  • Chattahoochee, Flint, Ocmulgee, and Oconee rivers
 Coastal Plain
  • Largest region, three-fifths of state
  • Inner Coastal Plain: Mild climate, good underground water supply, state’s major agriculture region
  • Outer Coastal Plain (southwest corner): rich soil for peanuts, pecans, corn, and pulp production
  • Low-lying freshwater wetlands such as the Okefenokee Swamp
