| Geography | The science of studying the Earth as the home of humans |
| Relative Location | describes where a place is compared with other places |
| Absolute Location | identifies a precise position on Earth's surface; often stated in latitude and longitude |
| Hemisphere | one-half of a sphere |
| Axis | an imaginary straight line around which an object rotates |
| Equator | the imaginary line that goes around the globe exactly halfway between the North pole and the South Pole |
| Parallels | an imaginary line that runs east to west side-by-side with the Equator; a latitude line |
| Latitude | a measure of the distance north or south of the Equator; expressed in degrees, minutes, and seconds |
| Meridians | a line that runs north and south from one pole to the other; a longitude measure |
| Prime Meridian | an imaginary line running from the North Pole through England and part of Africa through the South Pole |
| Longitude | a measure of the distance east or west of the Prime Meridian; expressed in degrees, minutes, and seconds |
| Precipitation | rain, hail, sleet, or snow |
| Wetland | a low-lying land area where water lies close to the surface creating sloughs, swamps, bogs, ponds, and freshwater marshes; a lowland that is influenced by tidal water flows |
| Estuary | a body of water where freshwater rivers and salt water mix; examples include sounds, marsh, creeks, and tidal rivers |
| Region | an area of the Earth's surface that is defined by certain unifying characteristics |
| Climate | the type of weather a region experiences over a long period of time |
| Weather | the day-to-day conditions and changes in the atmosphere |
| Blue Ridge | a physiographic region of Georgia located in the northeastern part of the state |
| Ridge and Valley | a physiographic region of Georgia that lies between the Blue Ridge Mountains and the Appalachian Mountains |
| Appalachian Plateau | a physiographic region of Georgia in the far northwestern corner of the state |
| Piedmont | a physiographic region of Georgia that begins in the mountain foothills of northern Georgia and goes to the central part of the state |
| Coastal Plain | a physiographic region of Georgia that runs from the coast to the Piedmont Plateau |
| Fall Line | the point at which hilly or mountainous lands meet the coastal plain |
| Okefenokee Swamp | the largest freshwater wetland in Georgia |
| Appalachian Mountains | a chain of mountains that runs into Georgia, its famous trail ends here |
| Chattahoochee River | a river that runs from the mountains of north Georgia to the Gulf of Mexico; part of its southern section forms the natural border between Georgia and Alabama |
| Savannah River | the only river that flows into Georgia from outside its borders; this river forms a natural boundary between Georgia and South Carolina |
| Barrier Islands | islands along the coast which protect the beaches by blocking much of the wind, water, and sand that could erode the mainland |
| Wind Current | a continuous movement or flow of air |
| Trade Winds | winds from the Equator to around 30 degrees north latitude that generally flow from the northeast |
| Prevailing Westerlies | winds from around 30 degrees E to 60 degrees E north and south of the Equator that generally blow from the west to the east |
| Ocean Currents | rivers of the ocean water |
