a.Locate Georgia in relation to region, nation, continent, and hemispheres.
b.Describe the five geographic regions of Georgia: Blue Ridge Mountains, Valley
and Ridge, Appalachian Plateau, Piedmont, and Coastal Plain.
c.Locate and evaluate the importance of key physical features on the

Mountains, Chattahoochee and Savannah Rivers, and barrier islands
d.Evaluate the impact of climate on Georgia’s development

5 Regions of Georgia
Also known as Physiographic
Regions
Coastal Plain
Piedmont
Ridge and Valley
Blue Ridge
Appalachian Plateau
Coastal Plains
Northern boundary: Fall Line
Largest region (60% of GA
below the Fall Line)
Inner (Northern)
Agricultural- clay, sand and
limestone soil
Vidalia Upland FLAT, No hills
Peanuts, peaches, pecans
Outer (Southern)
Coastal
Swamp/Marsh
Okefenokee Swamp
Barrier Islands:
Purpose: protect the beaches
Protect beaches
Continental Shelf:
Protects our coast from
hurricanes
Coastal Plains II
Prehistoric ocean extended to the Fall
Line
Fossils of shark teeth, whale bones and
various ocean life found in Coastal
Plains – phosphate, limestone bauxite
75 miles from coast line inland is
known as
“The Pine Barrens”
Hardly anything except pine trees grows
in this region!
Swamps rivers, streams, estuaries, and
islands.
Slow, meandering, widening rivers
Tidal rivers along coastline…saltwater
and freshwater share areas during the
tides as far as 10 miles inland.
Coastal wetlands… Okeefenokee
Swamp
Piedmont
“Foot of the Mountains” -Over 50% of the states population
Located between the Coastal Plain
and mountains of North GA
Encompasses 30% of state’s area
Gently sloping and rolling hills,
streams, rivers lakes
Business and Industry region
Cotton, soybean, wheat, beef and
dairy cattle, chicken…
Georgia “Red Clay”, solid rockgranite, marble, mica
Atlanta skyline…The Capitol
Blue Ridge
Located in Northeast GA
Highest and largest group of
mountains in Georgia , many rivers
begin here
Landmarks:
Tallulah Gorge
Beginning of the Appalachian Trail
Brasstown Bald
Mountains act as a barrier to keep in
the warm, moist air from the gulf
causing precipitation
Lots of rain
sleet, snow, hail
Short growing season- less than 1%
farmland- Apples, corn, vegetables,
and hardwood timber
Mica, feldspar gold and marble found
here!
Ridge and Valley Northwest GA-between Blue
Ridge and Appalachian Plateau
Low open valleys and narrow,
parallel ridges
”Wrinkles”
Flat fertile farmlands
Hardwood forest and pastures
Corn soybeans, wheat, cotton
Industrial: textile and carpet
The textile industry
manufacturing
DALTON: “Carpet Capital of the
World”
Lots of Limestone
Discussion:
Explain the importance of the barrier islands.
2. Why do you think approximately one-half of
Georgia’s population lives in the Piedmont region?
3. Explain why the Blue Ridge region has very little
farmland.
1.
Appalachian Plateau Smallest region FAR NW Ga
(includes only Dade County).
Lookout Mt./ Sand Mt.
Most scenic but least traveled
Called TAG Corner
Tennessee
Alabama
Georgia
Gentle slopes with mountains
over valleys
Hardwood forest, pastures for
livestock, corn and soybean.
Only known source of coal in
Georgia; Iron
Key Physical Features
Fall Line
Stretches across GA
from Augusta through
Macon to Columbus
Marks the transition
from Coastal Plain to
the Piedmont
Home of Georgia’s most
important mining
operations
Kaolin
Appalachian Mountains
Stretch from Canada to
Alabama
Highest point in GA:
Brasstown Bald
Mountain—4784 ft.
above sea level
Savannah River
Chattahoochee River
Key Physical Features (cont.)
Okefenokee Swamp
Approx. 7000 years old; peatfilled bog inside a saucershaped depression that was
once part of the ocean floor
Derives its name from
Choctaw Indian words
meaning "Land of the
Trembling Earth."
Covers 438,000 acres. It is 38
miles in length at its longest
point by 25 miles in width at
its widest point. The swamp
is approximately 700 square
miles.
Key Physical Features (cont.)
Savannah River
First European explorers
reached the Savannah
River in 1540 (though
Native Americans had
been using the waterway
for many years)
Headwaters in SC (only
river that flows into GA
from outside its borders)
Chattahoochee River
Cherokee: “river of the
painted rock”
Supplies water to Atlanta
and Columbus
Flows 436 miles; begins as
a small stream near
Brasstown Bald
Joins the Flint River near
the FL state line, becomes
the Apalachicola River and
empties into the Gulf of
Mexico at Apalachicola
Bay
What impact does climate have on
Georgia’s development?
Weather: day-to-day conditions
Climate: type of weather experienced by a place over a long
period of time
Georgia’s climate: mild with subtropical feel near coast
Allows for lower heating/air costs for companies; less weather
related absences
Precipitation:
Snow—falls mainly in the mountains, melts and runs off into streams
and lakes
Rainfall—aids the growth of crops and forests
Average rainfall—40-52” in central and southern regions; 65-76” in
the northern mountains (some in the form of snow)
Drought: 1998-2002—harmed industries, residents
500 year flood: September 2009
Atlanta Flooding: September 2009
September 15-23, 2009
Caused by continuous rain, spawned
by moisture from the Gulf of Mexico
Est. damages: $500 million
10 deaths
20,000 homes, businesses, and other
buildings received major damage; 17
counties named ‘federal disaster
areas’
Many Georgians unprepared—
considered 500 year flood
