2Georgia and the American Experience Section 1: What is Geography?Section 2: Geographic Regions of GeorgiaSection 3: Georgia’s Climate
3Section 1: What is Geography? Essential Question- What roles do the essential elements of geography play in our lives?
4Section 1: What is Geography? What geographic terms do I need to know?-- geography-- absolute location-- relative location
5What 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.
6Understanding Georgia: Spatial Geography Spatial: How Georgians organize their space and environment:159 counties (2nd most of all of the states)five bordering stateslargest state east of the Mississippi
8Understanding Georgia: Places and Regions Places and Regions: People create regions to understand Earth’s complexitiesGeorgia has five physiographic regions18 islands58, 910 square miles854 square inland water miles
9Understanding Georgia through Geography Physical Systems: Physical processes that shape the earth’s surfaceCoastal islands (southeast Georgia)Appalachian Mountains (north Georgia)Fall Line divides east and west Georgia
11Understanding Georgia: Human Systems Human Systems: Where Georgians migrated and settledAtlanta (Fulton County) is the capitalTwiggs County (geographic center)Port of Savannah (first major settlement)Brasstown Bald (highest geographic point)
12The Geographic center of Georgia is located in Twiggs County. The highest point in Georgia is Brasstown Bald(4,784 ft).
13Understanding Georgia: Environment and Society Environment and Society: Actions of humans modify the environmentSuburban sprawl in metropolitan AtlantaInterstates and highwaysUrban population centersRural farmlands and agricultural regions
14Urban sprawl is the unregulated growth of metropolitan areas.
15Agriculture is an important component of Georgia’s economy.
16Understanding Georgia: Uses of Geography Uses of Geography: Interpret Georgia’s past, understand its present, plan for its futureLocation from one settlement to another affects how each settlement developsGeorgia’s location relative to other states affects Georgia’s growth and economic development
17Understanding Location Absolute location: A precise position on Earth’s surfaceGeorgia is located at 30°– 35°N latitude, 80°– 85° W longitudeGeorgia borders Florida (south), Alabama (west), Tennessee and North Carolina (north), and South Carolina (east).
18Understanding Location Relative Location: Where Georgia is located compared with other placesNorth AmericaSoutheastern United StatesAtlantic coast.
19Section 2: Geographic Regions of Georgia ESSENTIAL QUESTION-- How would you describe the geographic regions of Georgia?
20Section 2: Geographic Regions of Georgia What words do I need to know?-- Fall Line-- Region-- Precipitation-- Wetland-- Barrier Island-- Continental Shelf
21Section 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
22GA’s 5 geophysical regions. Which is Largest? Smallest? What separates the Coastal Plain and the Piedmont?
23Appalachian Plateau Region Georgia’s smallest physiographic regionMany limestone caves, deep canyons, rock formationsCumberland Plateau (Lookout Mountain and Sand Mountain separated by limestone ridges)Limestone, shale, and sandstone soils“TAG corner”
24Ridge and Valley Region Between Blue Ridge Mountains and Appalachian PlateauLow open valleys parallel to narrow ridgesElevations ranges from 700 to 1600 feet above sea levelForests and pastures dominate the regionLimestone and clay soils in the valleyShale and sandstone on the ridges
25Blue Ridge Region Northeastern part of state Contains state’s highest and largest group of mountainsBrasstown Bald, Georgia highest mountain is hereMountains provide much precipitation (water) for the stateSandy loam and clay soilsHardwood forests, vegetable farming, and apples
26Piedmont PlateauBegins in mountain foothills and goes to state’s central partGently sloping hills in north, flatlands in the southHardwood timber, pine, and agricultureRed clay and granite baseChattahoochee, Flint, Ocmulgee, and Oconee rivers
27Coastal Plain Region Largest region, three-fifths of state Inner Coastal Plain: Mild climate, good underground water supply, state’s major agriculture regionOuter Coastal Plain (southwest corner): rich soil for peanuts, pecans, corn, and pulp productionLow-lying freshwater wetlands
28Okefenokee Swamp 681 square miles Located south of Waycross Largest swamp in North AmericaFreshwater wetlandWater lies close to the surface
29Islands of GoldSpanish explorers called the barrier islands “islands of gold”Protect beaches by blocking sand, winds, and water that could erode the mainlandTwo-thirds remains wilderness areasMuch recreation, seafood gatheringDeep water ports for shipping
30Shelves and LinesGeorgia’s continental shelf is portion of coastal plain that extends into the oceanThe Continental slope falls into deep plateaus and into the Atlantic Ocean depthsThe Fall Line, a natural boundary, separates the Coastal Plain from the Piedmont Plateau
31Fall 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 plainsFall Line waterfalls provide power source for several Georgia communities
32Section 3: Georgia’s Climate ESSENTIAL QUESTION-- How would you describe the climate of Georgia?
33Section 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
34Georgia’s Temperature Mild climate, subtropical feel along the coastHot, humid summers and mild wintersFour distinct seasons: Spring, Summer, Fall, and WinterVertical climate (higher elevation in mountains causes colder temperatures)July is hottest month; January is coldest
35Georgia’s Precipitation In normal year, Georgia gets inches of rain in central and southern regions and inches in the northern mountainsJuly is wettest month; October is driestFrom 1998 to 2002, Georgia experienced a major drought (extended lack of precipitation)
36Winds and CurrentsAir 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.
37Storms over GeorgiaGeorgia averages 21 tornadoes each year, resulting in one to three deathsMost tornadoes in Georgia occur from March to MayGeorgia’s most hurricane-like storm (in terms of lives lost) occurred in Savannah in 1893Called the “Sea Islands Hurricane,” the storm resulted in 1,000 deaths.
