Georgia is bordered on the south by Florida; on the east by the Atlantic Ocean and South Carolina; on the west by
Alabama and by Florida in the extreme southwest; and on the north by Tennessee and North Carolina. The northern part
of the state is in the Blue Ridge Mountains, a mountain range in the vast mountain system of the Appalachians. The
central piedmont extends from the foothills to the fall line, where the rivers cascade down in elevation to the
continental coastal plain of the southern part of the state. The highest point in Georgia is Brasstown Bald, 4,784
feet (1,458 m); the lowest point is sea level.
The majority of Georgia is primarily a humid subtropical climate tempered somewhat by occasional polar air masses
in the winter. Hot and humid summers are typical, except at the highest elevations. The entire state, including the
north Georgia mountains, receives moderate to heavy precipitation, which varies from 45 inches (1143 mm) in central
Georgia to approximately 75 inches (1905 mm) around the Northeast part of the state. The degree to which the
weather of a certain area of Georgia is subtropical depends not just on the latitude, but also on how close it is to
the Atlantic Ocean or Gulf of Mexico and the altitude. This is especially true in the mountainous areas in the
northern part of the state, which are further away from ocean waters and can be up to 4500 feet (1350 m) or higher
above sea level.
