Warm-UpCompare and Contrast these pictures. What do

these pictures tell you about the different physiographic regions of Georgia?

Geographic Regions of Georgia

SS8G1 The student will describe Georgia with regard to physical features and location. b. Describe the five geographic regions of Georgia; include the Blue Ridge Mountains, Valley and Ridge, Appalachian Plateau, Piedmont, and Coastal Plain. c. Locate and evaluate the importance of key physical features on the development of Georgia; include the Fall Line, Okefenokee Swamp, Appalachian Mountains, Chattahoochee and Savannah Rivers, and barrier islands.

So…Where in the world is Georgia??

• Region?• Nation?• Continent?• Hemispheres?

Terms to Know:

• Physiogeographic• Region• Precipitation• Wetland• Barrier Island• Continental Shelf• Fall Line

Georgia has 5 physiographic regions.

• Appalachian Plateau• Ridge and Valley• Blue Ridge• Piedmont• Coastal PlainThe characteristics of each region make

unique contributions to our state.

Appalachian Plateauaka: Cumberland Plateau/ TAG corner

• Our smallest physiogeographic region• From Lookout Mt. to Sand Mt. with ridges of

limestone & a long narrow valley in between • Soil of limestone, shale & sandstone = hardwoods

and pastureland• Our only significant coal deposits.

Ridge and Valley• Lower elevation than Appalachian Plateau • Low open valleys and narrow ridges• Soil good for forests, pastures, and crops such as

grain and apples (Ellijay)• Industry includes textiles and carpet (Dalton is the

carpet capital of the world)

Blue Ridge Images

Brasstown Bald: You can see 3 states from this point. Can you name them?

Helen, Georgia has a strong German influence. Why do you think that is? How does the town of Helen contribute to our state?

Amicalola Falls

Ga. Fruits & Vegetables

Blue Ridge• Highest mts. in the state including Brasstown

Bald- Georgia’s highest point.• 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• Beginning of Appalachian Trail, home to Amicalola

Falls, Tallulah Gorge, and Helen• See it while you can. Erosion continues to wear

down the height of the mountains.

Piedmont Images

Why do you think most of Georgia’s major cities are located in the Piedmont region?

Sandy loam and red clay are make good soil for agriculture.

Piedmont: “Foot of the mountain” • Begins in the mountain foothills of N. Georgia and

goes to the central part of the state.• You live in the Piedmont region.• Granite based foundation (What’s our largest granite

outcropping?)• Soil is sandy loam and red clay suitable for growing

hardwoods, pine, and agriculture.• 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.

Coastal PlainThere are two parts to Georgia’s coastal plain:• The Inner Coastal Plain• The Outer Coastal

Plain

Which color do you think represents the Inner Coastal Plain and which color represents the Outer Coastal Plain? Why?

The Inner Coastal Plain• Good supply of underground water• Major agricultural region: Vidalia Onions,

peanuts, pecans, and corn • Why do you think President Jimmy Carter was

known as “The Peanut Farmer from Georgia” during his campaign?

Outer Coastal Plain Images

Trees are used to produce pulp and naval stores. The processed goods are then shipped from our shores.

Why do you think a British flag flies over Fort Frederica?

Early map of Savannah

Our shores continue to bring visitors to our state.

The Outer Coastal Plain• Soil not good for agriculture but trees provide

naval stores and pulp production (Naval Stores – originally meant wood for ship building. Now it refers to products produced from pine trees – pine old, tar, rosin, turpentine, etc..)

• Deep harbors and barrier islands also provide for tourism/recreation, fishing industry, and ports for importing/exporting goods.

• Location of the earliest visits by European explorers, first forts for protection, and Georgia’s first settlements. Why?

Other Important Coastal Plain Features• 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)

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. The same marsh at high tide.

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.

Other Georgia Geographic Features• Continental Shelf:– Where the land meets the sea

• The Fall Line:– Where hilly land meets the coastal plain– Runs from Columbus through Macon to Augusta– Prevented exploration but provided for settlements

Chattahoochee River• First steamboat ran in 1828 making

Columbus a thriving cotton-marketing center with river travel north and south

• By the late 1830’s, towns located at the Fall Line along the Chattahoochee also used the river as an industrial power source for textile mills and grist mills

• Played an integral role in the Civil War • Present day—the river is now more

valued for its drinking water and recreation activities

• Georgia, Alabama, and Florida are currently in a legal battle over the unrestricted right to use the river
