Questions this course answers

What sequence best describes a flight across Georgia from north to southeast?

Georgia's physiographic regions descend from Appalachian highlands through the Piedmont to the Coastal Plain and Atlantic coast.

Why did Georgia's Fall Line help cities grow?

The boundary between harder Piedmont rock and softer Coastal Plain sediment creates rapids and falls, making navigation and water power consequential.

What makes the Okefenokee a two-direction watershed?

Most Okefenokee water leaves through the Suwannee toward the Gulf, while the St. Marys carries the remainder toward the Atlantic.
