Chapter 2 — The Land of Georgia

1. Physical Geography

• Physical geography = the study of Earth’s physical features and how they are arranged.

• Landform = a natural formation on Earth’s surface.

• Elevation = the height of land above sea level.

• Relief = the difference in elevation between the lowest and highest points of an area.

• Slope = how steep a piece of land is.

• Precipitation = water that falls from the atmosphere, such as rain, snow, sleet, or hail.

• Erosion = the wearing away and movement of soil and rock by forces such as water and wind.

2. Georgia’s Five Physiographic Regions

A physiographic province/region is an area with similar physical characteristics, including landforms, elevation, rocks, minerals, and soils. Georgia has five major regions. 

🌊 Coastal Plain

• Largest region in Georgia.

• Covers about 60% of the state.

• Located south of the Fall Line.

• Mostly flat and low land.

• Has clay, sand, and limestone soils.

• Important crops include:

  • Peanuts

  • Peaches

  • Pecans

• Contains the Okefenokee Swamp.

• Important minerals include kaolin, limestone, phosphate, and fuller’s earth. 

🟥 Piedmont

• Located between the Coastal Plain and the mountains.

• Covers roughly 30% of Georgia.

• Characterized by rolling hills and valleys.

• Famous for its red clay soil.

• Red clay gets its color from iron minerals.

• Has a lot of exposed bedrock, including granite, gneiss, and marble.

• Important agriculture includes:

  • Cotton

  • Soybeans

  • Wheat

  • Cattle

  • Poultry

  • Pine trees 

⛰ Blue Ridge Mountains

• Located in northeast Georgia.

• Contains Georgia’s highest mountains.

• Brasstown Bald is the highest point in Georgia.

• Receives a lot of rainfall because of its elevation.

• Many rivers begin in this region.

• Farming is more difficult because of steep land and a shorter growing season.

• Apples, corn, vegetables, and hardwood trees are important products. 

🏔 Ridge and Valley

• Located in northwest Georgia.

• Has long, parallel ridges with valleys between them.

• Elevation is generally higher than the Piedmont.

• Important products include:

  • Corn

  • Soybeans

  • Wheat

  • Cotton

  • Hardwood and pine trees

• Minerals include limestone, bauxite, and barite. 

🪨 Appalachian Plateau

• Smallest of Georgia’s five regions.

• Located in the far northwest corner.

• Has flat or gently sloping land above deep valleys.

• Includes Lookout Mountain and Sand Mountain.

• Has relatively little farmland.

• Minerals include coal and iron. 

3. The Fall Line ⭐

The Fall Line is one of the most important things to remember for a test.

• It separates the Piedmont from the Coastal Plain.

• It marks approximately where the shoreline of a prehistoric ocean once existed.

• Rivers flowing from the Piedmont toward the Coastal Plain drop in elevation.

• This creates rapids and waterfalls.

• The falling water could be used as a source of water power.

• Mills and factories were built along the Fall Line.

• Important cities that developed along it include:

  • Columbus

  • Macon

  • Augusta 

Easy way to remember:

Fall Line = water falls → water power → cities and industry.

4. Okefenokee Swamp

• Located in southeastern Georgia.

• It is Georgia’s largest freshwater wetland.

• It is an extremely important ecosystem.

• It contains many different species of plants and animals.

• The name is associated with the idea of “land of the trembling earth.” 

Why is it important?

It provides:

• Wildlife habitat

• Wetlands

• Recreation

• Natural resources

• Protection for many species

5. Georgia’s Rivers

Chattahoochee River

• Begins in the Blue Ridge Mountains.

• Flows south toward the Gulf of Mexico.

• Forms much of the border between Georgia and Alabama.

• Provides water for:

  • Cities

  • Farming

  • Businesses

  • Recreation 

Savannah River

• Forms much of the border between Georgia and South Carolina.

• Flows into the Atlantic Ocean.

• Important for:

  • Transportation

  • Shipping

  • Hydroelectric power

  • Water supply 

Why are rivers important?

Georgia’s rivers provide:

• Drinking water

• Transportation

• Hydroelectric power

• Irrigation

• Recreation

• Water for businesses and industries

6. Georgia’s Barrier Islands

• Barrier islands are islands located along Georgia’s coast.

• They help protect the mainland from storms and waves.

• Examples include:

  • Tybee Island

  • St. Simons Island

  • Jekyll Island

  • Cumberland Island

• Where rivers meet the ocean, estuaries form.
