Georgia’s Key Physical Features Appalachian Mountains The Fall Line Barrier Islands Okefenokee Swamp The Fall Line •Natural Boundary; Separates the Piedmont and Coastal Plain •Stretches from Columbus, through Macon, into Augusta •Elevation drops & creates waterfalls •Early settlers found waterfalls a source of power •Prehistoric ocean shoreline •Location of mining operations; kaolin – clay used in paints, rubber, cement, fertilizers – most important use in paper (gloss) Okefenokee Swamp •Located in Coastal Plain •It is a freshwater wetland; home to prehistoric Indians •Pioneers move here & herded cattle, fished and hunted •Railroads appeared around 1830 & sawmills, turpentine stills and stores sprang up •Logging became a big industry until 1929 when it became a National Wildlife Refuge Appalachian Mountains •Stretch from Canada in the NE to Alabama in the SW •Large areas of commercial forests •Marble industry one of the largest employers. •Coal is found in this region; $1.6 billion a year •Popular tourist spot Chattahoochee River •436 miles from North Georgia to the Gulf of Mexico •Southern section is border between GA & Alabama Alabama Georgia •Home of Prehistoric Native Americans – food source and Florida travel •Industrial power source & water source •Lake Sidney Lanier is a reservoir on the river – Georgia’s largest city, Atlanta gets its drinking water from this river system Savannah River •314 miles; border between Georgia & South Carolina South Carolina Georgia •Important seaport; industrial power source •Attracted early settlers and industry as Georgia grew Barrier Islands •Chain of sea islands; form a wall that blocks waves and winds from hitting the mainland •Recreation & tourism boosts Georgia’s economy Atlantic Intracoastal Waterway •1,000 mile inland waterway that runs from New York to Miami, Florida •Important shipping lane for cargo ships Georgia’s Ports •Savannah & Brunswick are major deepwater ports •Savannah’s seaport concentrates on containerized cargo •Brunswick’s seaport concentrates on auto shipping, farm machinery and luxury tour buses •Exceeds $1.8 Billion in yearly income & over 81,000 jobs Major Lakes •Most of Georgia’s lakes are manmade. •Lakes provide hydroelectric power, water storage reservoirs & recreation facilities. Georgia’s Water Supply •Southern half of Georgia has groundwater; stored in underground layers of rocks & gravel called aquifers. •Water is not an endless resource; conservation is important. •North Georgia does not have easily accessible groundwater due to the bedrock. •North Georgia relies on surface water; reservoirs (holding tanks) constructed to help water needs
