B)the Valley and Ridge region

C)the Fall Line

D)the Marshes of Glynn<<??

Check my answer please.

I guess so, but living in a fishing town I do not call salt marshes an "obstacle".

To determine the correct answer, let's break down the question and explore the options:

The question asks about the geographic feature that marks the last natural obstacle for Georgia's rivers on their way to the Atlantic Ocean.

A) The Floridian Aquifer: The Floridian Aquifer is a large underground water resource, primarily located in Florida. It does not serve as a natural obstacle for Georgia's rivers.

B) The Valley and Ridge region: The Valley and Ridge region is a geographic area located in Georgia, but it does not act as the last natural obstacle for the rivers.

C) The Fall Line: The Fall Line is the correct answer. It is a geographic feature that marks the boundary between Georgia's coastal plain and the Piedmont region. It represents the point where rivers encounter rapids or waterfalls due to the change in elevation. The Fall Line acts as the final barrier for Georgia's rivers before they reach the Atlantic Ocean.

D) The Marshes of Glynn: The Marshes of Glynn is a natural area located in coastal Georgia. While it is an important ecosystem, it does not serve as the last natural obstacle for the rivers on their way to the Atlantic Ocean.

Based on the explanation provided, the correct answer is C) the Fall Line.
