LET’S LOCATE GEORGIA IN RELATION TO REGION, NATION, CONTINENT, AND HEMISPHERE. Earth is a sphere. A sphere can be divided into two halves called “hemispheres.” Equator • Divides the northern and southern hemispheres Prime Meridian • Divides the eastern and western hemispheres Continents • There are 7 continents: Europe, Asia, Australia, Africa, Antarctica, North America, and South America Georgia is on the Northern AND Western hemispheres Northern Hemisphere Western Hemisphere Georgia is on the North American continent. Georgia is one of the 50 states in the United States of America Georgia is in the southeastern region of the US.

Describe the five geographic regions of Georgia; include the Blue Ridge Mountains, Valley and Ridge, Appalachian Plateau, Piedmont, and Coastal Plain. The Regions of Georgia © 2010 Clairmont Press Geographic Regions of Georgia Appalachian Plateau Coastal Plains Piedmont Blue Ridge Mountains Ridge and Valley What is Physical Geography? • The study of the natural features of the earth's surface, especially in its current aspects, including land formations, climate, currents, and distribution of flora and fauna. Also called physiography Georgia has 5 geographic regions. • • • • • Appalachian Plateau Valley and Ridge Blue Ridge Piedmont Coastal Plain The characteristics of each region make unique contributions to our state. Appalachian Plateau Region • Also called the TAG corner because Tennessee, Alabama, and Georgia connect • Smallest region in GA • Mining was an important economic activity in the region. • Coal was the most important product. 19 Appalachian Plateau • the location of Cloudland State Park. • Northwest corner of Georgia • Ellison’s Cave is 12th largest cave Valley and Ridge Region • long ridges of mountains, separated by long valleys. • Chickamauga – (Civil War battle) • Valleys have fertile land good for farming. • Roads and streams follow the valleys. A few roads cross the ridges to connect roads in the valleys. • traditionally a mining region, with the valleys being used for agriculture. • Natural resources – farmland, rock, and timber 21 Valley and Ridge • Lower elevation than Appalachian Plateau • Soil good for forests, pastures, and crops such as grain and apples • Industry includes textiles and carpet (Dalton is the carpet capital of the world) Blue Ridge Mountains Region • The Blue Ridge range is a part of the larger Appalachian Mountains. • The mountains are more rugged and the valleys randomly arranged as compared to the Ridge and Valley region. • Most roads follow the winding valleys. • Elevations of 1,600 to 4,700 feet above sea level give the region a cooler climate. • Brasstown Bald (4,784 feet) is tallest mountain. • Appalachian Trail begins here. • Gold has been found in the region, and marble is an important natural resource. • Tourists come to hike, view wildlife, canoe, raft, and enjoy trees in their fall colors. • Highest rainfall amounts in GA 23 Blue Ridge • Highest mts. in the state. • Provides water for the entire state through precipitation from trapping warm moist Gulf air • Sandy loam and clay soil good for hardwoods, vegetable farming and apples • Home to Amicalola Falls, Tallulah Gorge, and Helen • 1800’s gold was found – first gold rush in US • Cherokee Native Americans lived here until forced off their land Blue Ridge Images Brasstown Bald: You can see 3 states from this point. Can you name them? Amicalola Falls Think…. • What are the significant physical features of Georgia that have impacted its development? Piedmont Region • The Piedmont is known for its rolling hills between the mountains and Coastal Plain. • Plentiful granite and clay soil with fertile farms. • Many Georgians live in the region. • Rivers flow through the Piedmont, including the Chattahoochee and Savannah. • Southern boundary is the Fall Line. • Changes in rock type cause the ground to fall away, creating waterfalls at the “fall” line across the state. 27 Lakes and Rivers of Georgia • Cities grew along the Fall Line since ships could navigate from the Atlantic to this point (Augusta: Savannah River; Milledgeville: Oconee River; Macon: Ocmulgee River; Columbus: Chattahoochee River). Piedmont • Piedmont means “foot of the mountain” • Begins in the mountain foothills of N. Georgia and goes to the central part of the state. • Rolling farmland • Soil is sandy loam and red clay suitable for growing hardwoods, pine, and agriculture. • Granite mining and cotton production important in region • Cotton belt before the Civil War, now wheat, soybeans, corn, poultry, and cattle. • Some of the most densely populated cities and crossed by Chattahoochee, Flint, Ocmulgee, and Oconee rivers. Piedmont • • • • • Largest populated region Rolling Hills Chattahoochee River flows through this region Stone Mountain is located in this region Atlanta is located in this region Piedmont Images Georgia’s Flint River Why do you think most of starts in Clayton County. Georgia’s major cities are located in the Piedmont region? Why do you think most of Georgia’s rivers start in the Piedmont region? Sandy loam and red clay make good soil for agriculture. Stone Mountain Coastal Plain Region • • • • • • the southern half of state and is the largest region. Lower coastal plain has Georgia’s barrier islands, 100 miles of coastline, marshes, and the Okefenokee Swamp. Flatland makes for highways that are straight and level. Home to many types of wildlife. Farming is important to the region’s economy. Loblolly and slash pines are grown in the region today for lumber. Tybee Island, GA 32 Coastal Plain Region • Once covered by the Atlantic • Aquifers are the largest source of fresh water • Low, flat, marshland • Okefenokee Swamp located in region • Rivers in this region are used for shipping and recreation • You live in this region. 33 Coastal Plain There are two parts to Georgia’s coastal plain: •The Inner Coastal Plain •The Outer Coastal Plain The Inner Coastal Plain • Good supply of underground water • Major agricultural region: Vidalia Onions, peanuts, pecans, and corn Pecans Vidalia Onions GA Peanuts Corn The Outer Coastal Plain • Soil not good for agriculture but trees provide naval stores and pulp production • Deep harbors & barrier islands also provide for tourism/recreation, fishing industry, and ports for importing/exporting goods. • Location of the earliest visits by explorers, first forts for protection, and Georgia’s first settlements. Outer Coastal Plain Images Trees are used to produce pulp and naval stores. The processed goods are then shipped from our shores. Fort Frederica National Monument, on St. Simons Island, Georgia, preserves the archaeological remnants of a fort and town built by James Oglethorpe between 1736 and 1748 Our shores continue to bring visitors to our state.

Okefenokee Swamp – Covers 681 square miles making it the largest swamp in North America – Freshwater wetland (wetland: low-lying land area where water lies close to the surface) – Native Americans from the Archaic period lived here – Area is protected by the federal government Okefenokee Swamp See the Okefenokee like never before: http://www.gpb.org/georgiaoutdoors/season-18/episode/okefenokee Another type of wetland • Salt Marshes: – A wetland that is influenced by tides – Georgia ranks 4th in the nation in wetland acres A marsh at low tide. tide. The same marsh at high Georgia’s Barrier Islands “Islands of Gold” • Barrier islands protect the mainland from wind, sand, and water that cause erosion. • Georgia has 18 barrier islands. • These islands are tourist destinations but 2/3 of the land remains wilderness sanctuaries. Barrier Islands Fall Line natural boundary between the Piedmont and Coastal Plain regions Appalachian Mountains • The southernmost point of the Appalachian Mountains is located in Georgia. • Georgia’s highest peaks are in here. • In the southern states these mountains are often called the Blue Ridge due to the blue haze that appears around their peaks. • The highest peak in Georgia is Brasstown Bald, w/ an elevation over 4700 ft. above sea level. Appalachian Mountains Chattahoochee River • begins in Blue Ridge region of GA and ends at the Gulf of Mexico • forms part of the border b/t Alabama and Georgia • Native Americans & European settlers long used the river as a food and water source. • Today, river is used as water source, for industry, and for recreation Chattahoochee River Savannah River • forms the border between Georgia and South Carolina • One of Georgia’s longest waterways • The river has been a source of water, food, and transportation for thousands of years. • Historically, it was used for three reasons: – Transportation – cultures could move to other places easier – Settlement – allowed cultures to settle near a steady source of food – Economic – allowed cultures to trade with others Savannah River continued… • Today, the river is navigable for over 200 miles between the city of Savannah and Augusta • In addition to shipping, the river, today, is used as a major source of drinking water for Savannah and Augusta, to cool two nuclear power plants in South Carolina, and to generate hydroelectric power.
