Section 3: Georgia’s Climate

Section 1: What is Geography?

• Essential Question

- What roles do the essential elements of geography play in our lives?

Section 1: What is Geography?

• What geographic terms do I need to know?

-- geography

-- absolute location

-- relative location

What is Geography?

• Geographica (Greek origin) means “earth’s description”.

• Science of studying Earth as the home of humans.

• Geography helps us understand why Georgia’s native peoples and later settlers chose certain parts of the state for their home.

Understanding Georgia: Spatial Geography

• Spatial: How Georgians organize their space and environment: –159 counties (2nd most of all of the

states) – five bordering states– largest state east of the Mississippi

Only Texas has more counties

than Georgia.

Understanding Georgia: Places and Regions

• Places and Regions: People create regions to understand Earth’s complexities

• Georgia has five physiographic regions• 18 islands• 58, 910 square miles • 854 square inland water miles

Understanding Georgia through Geography

• Physical Systems: Physical processes that shape the earth’s surface

• Coastal islands (southeast Georgia) • Appalachian Mountains (north Georgia)• Fall Line divides east and west Georgia

Understanding Georgia: Human Systems

• Human Systems: Where Georgians migrated and settled

• Atlanta (Fulton County) is the capital • Twiggs County (geographic center)• Port of Savannah (first major

settlement)• Brasstown Bald (highest geographic

point)

The Geographic center of Georgia is located in

Twiggs County.

The highest point in Georgia is Brasstown

Bald(4,784 ft).

Understanding Georgia: Environment and Society

• Environment and Society: Actions of humans modify the environment

• Suburban sprawl in metropolitan Atlanta• Interstates and highways • Urban population centers • Rural farmlands and agricultural regions

Urban sprawl is the unregulated growth of metropolitan areas.

Agriculture is an important component of Georgia’s economy.

Understanding Georgia: Uses of Geography

• Uses of Geography: Interpret Georgia’s past, understand its present, plan for its future

• Location from one settlement to another affects how each settlement develops

• Georgia’s location relative to other states affects Georgia’s growth and economic development

Understanding Location

• Absolute location: A precise position on Earth’s surface

• Georgia is located at 30°– 35°N latitude, 80°– 85° W longitude

• Georgia borders Florida (south), Alabama (west), Tennessee and North Carolina (north), and South Carolina (east).

Understanding Location

• Relative Location: Where Georgia is located compared with other places

• North America • Southeastern United States• Atlantic coast

.

Section 2: Geographic Regions of Georgia

• ESSENTIAL QUESTION

-- How would you describe the geographic regions of Georgia?

Section 2: Geographic Regions of Georgia

• What words do I need to know?

-- Fall Line

-- Region

-- Precipitation

-- Wetland

-- Barrier Island

-- Continental Shelf

Section 2: Geographic Regions of Georgia

• What regions do I need to know?

-- Appalachian Plateau Region

-- Ridge and Valley Region

-- Blue Ridge Region

-- Piedmont Plateau

-- Coastal Plain Region

-- Okefenokee Swamp

GA’s 5 geophysical regions. Which isLargest?Smallest?

What separates the Coastal Plain and the

Piedmont?

Appalachian Plateau Region• Georgia’s smallest physiographic region • Many limestone caves, deep canyons,

rock formations• Cumberland Plateau (Lookout Mountain

and Sand Mountain separated by limestone ridges)

• Limestone, shale, and sandstone soils• “TAG corner”

Ridge and Valley Region• Between Blue Ridge Mountains and

Appalachian Plateau • 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 Region • 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

• Begins in mountain foothills and goes to state’s central part

• 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 Region

• 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

Okefenokee Swamp

• 681 square miles• Located south of Waycross• Largest swamp in North America• Freshwater wetland• Water lies close to the surface

Islands of Gold

• Spanish explorers called the barrier islands “islands of gold”

• Protect beaches by blocking sand, winds, and water that could erode the mainland

• Two-thirds remains wilderness areas• Much recreation, seafood gathering• Deep water ports for shipping

Shelves and Lines

• Georgia’s continental shelf is portion of coastal plain that extends into the ocean

• The Continental slope falls into deep plateaus and into the Atlantic Ocean depths

• The Fall Line, a natural boundary, separates the Coastal Plain from the Piedmont Plateau

Fall Line Features

• Hilly or mountainous lands meet the coastal plain

• Runs from Columbus (west) through Macon to Augusta (east)

• Many waterfalls caused by water from the hills cutting channels into the softer soil of the plains

• Fall Line waterfalls provide power source for several Georgia communities

Section 3: Georgia’s Climate

• ESSENTIAL QUESTION

-- How would you describe the climate of Georgia?

Section 3: Georgia’s Climate

• What concepts do I need to know?

-- Difference between weather and climate

-- Effect of weather conditions on the state

-- Different types of weather phenomena

Georgia’s Temperature

• Mild climate, subtropical feel along the coast

• Hot, humid summers and mild winters• Four distinct seasons: Spring, Summer,

Fall, and Winter• Vertical climate (higher elevation in

mountains causes colder temperatures) • July is hottest month; January is coldest

Georgia’s Precipitation

• In normal year, Georgia gets 40-52 inches of rain in central and southern regions and 65-76 inches in the northern mountains

• July is wettest month; October is driest• From 1998 to 2002, Georgia

experienced a major drought (extended lack of precipitation)

Winds and Currents

• Air masses from Gulf of Mexico and the Atlantic Ocean control summer’s warm months.

• Air masses from polar regions of Alaska and Canada control Georgia’s winters.

• Ocean currents, trade winds, and prevailing westerlies aided travel for early explorers and settlers to Georgia.

Storms over Georgia

• Georgia averages 21 tornadoes each year, resulting in one to three deaths

• Most tornadoes in Georgia occur from March to May

• Georgia’s most hurricane-like storm (in terms of lives lost) occurred in Savannah in 1893

• Called the “Sea Islands Hurricane,” the storm resulted in 1,000 deaths.
