33 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Fall Line
- The boundary in Georgia between the crystalline Piedmont and the sedimentary Coastal Plain, marked by rapids and falls where rivers drop in elevation.
- Brasstown Bald
- Georgia's highest point at 4,784 feet (1,458 meters), located in the Blue Ridge province near the North Carolina border.
- Karst topography
- Landscape formed by dissolution of soluble bedrock such as limestone, producing caves, sinkholes, and disappearing streams, found in Georgia's Ridge and Valley and Coastal Plain.
- Piedmont soils
- Red, clay-rich soils derived from weathered crystalline rock, common across Georgia's Piedmont and prone to erosion when exposed.
- Humid subtropical climate
- Georgia's climate type, characterized by hot humid summers, mild winters, and precipitation distributed through the year with mountain orographic enhancement.
- Physiographic provinces of Georgia
- The five regions of Georgia: Appalachian Plateau, Ridge and Valley, Blue Ridge, Piedmont, and Coastal Plain, each with distinct bedrock, relief, and land use.
- Atlanta metropolitan dominance
- The pattern in which the Atlanta metropolitan area contains roughly half or more of Georgia's population and anchors the state's economy.
- Georgia agribusiness
- A major economic sector including poultry, peanuts, cotton, and pecans, with poultry concentrated in north Georgia and row crops on the Coastal Plain.
- Right-to-work state
- A state law status meaning union membership cannot be required as a condition of employment, shaping labor relations in Georgia manufacturing and logistics.
- Hartsfield-Jackson role
- Atlanta's airport, a leading global passenger hub that anchors Georgia's logistics, air cargo, and hospitality economies.
- Great Migration
- The twentieth-century movement of Black residents from the rural South, including Georgia, to northern and western cities, reshaping state demographics.
- Urbanization pressures
- Growth of metropolitan counties along interstate corridors, creating demand for housing, transportation, and water infrastructure in Georgia.
- Piedmont province
- A rolling upland underlain by crystalline rock, containing Atlanta, with red clay soils and dendritic stream networks.
- Coastal Plain province
- A low, gently sloping sedimentary region of Georgia with sandy soils, karst features, and barrier-island coastline.
- Ridge and Valley province
- A Georgia region of long parallel ridges and valleys formed on folded sedimentary rock, with farming concentrated in valley floors.
- Appalachian Plateau in Georgia
- A small, dissected area of flat-lying sedimentary rock in far northwest Georgia, including Lookout Mountain and Cloudland Canyon.
- Okefenokee Swamp
- A large peat-filled wetland in southeast Georgia fed mainly by rainfall and protected as a national wildlife refuge.
- Savannah River
- A river forming much of the Georgia-South Carolina border and supplying water and industrial uses along the Savannah region.
- ACF basin
- The Apalachicola-Chattahoochee-Flint river basin, central to interstate water allocation disputes among Georgia, Alabama, and Florida.
- Barrier islands of Georgia
- Sandy islands such as Sapelo and Cumberland, shaped by tides and longshore transport, protecting salt marshes and tidal creeks.
- Map scale
- The ratio of map distance to ground distance, expressed as a representative fraction, verbal statement, or graphic bar; larger fractions show more detail.
- Contour lines
- Lines on a topographic map connecting points of equal elevation; close spacing indicates steep slopes, and closed loops mark hills or depressions.
- UTM zones in Georgia
- Georgia spans Universal Transverse Mercator zones 16 and 17, used for metric coordinate mapping and field data collection.
- Choropleth map
- A thematic map shading areas by rate or density, useful for showing Georgia county-level population or income patterns.
- GIS overlay analysis
- A GIS operation combining layers, such as land cover and slope, to identify areas meeting multiple spatial criteria.
- USGS 7.5-minute quadrangle
- A standard topographic map at 1:24,000 scale covering 7.5 minutes of latitude and longitude, widely used for fieldwork in Georgia.
- Tri-state water dispute
- A long-running conflict among Georgia, Alabama, and Florida over allocation of shared river basins, especially the ACF and ACT.
- Nonpoint-source pollution
- Pollution carried by runoff from urban, agricultural, and construction areas rather than a single pipe, a leading cause of Georgia stream impairment.
- Floridan aquifer vulnerability
- The risk of depletion and saltwater intrusion in Georgia's coastal karst aquifer system from heavy pumping and sea-level rise.
- Conservation easement
- A legal agreement limiting development on private land to protect natural, agricultural, or scenic values, used in Georgia land conservation.
- Stratified sampling
- A fieldwork design dividing a study area into strata (such as land-cover types) and sampling within each to improve representativeness.
- Accuracy versus precision
- Accuracy is closeness to the true value; precision is repeatability of measurements, both important when recording coordinates and field data.
- Metadata in GIS
- Documentation of a dataset's source, date, projection, and processing steps, supporting reproducibility and appropriate use of geographic data.
