By learning about the geology of the Bahamas, an understanding of why the islands are the way they are today can be gained. An explanation of why the Bahamas are referred to as carbonate islands. Learning the geological conditions under which the Bahamas formed will help explain the subsurface hydrology and why karsts form. Also, the geological features on the Bahamas will show how easily the islands are eroded and show the effect on the continental shelf around the islands.

I. Introduction
a. State why geology is important to the Bahamas
b. Define basic geology terms
II. Tectonic evolution
III. Subsurface stratigraphy
IV. Modern depositional systems
V. Geomorphology
a. Shaping of the landscapes
b. Karst processes
c. Coastal effects and erosion
VI. Modern landscapes and how the geology of the islands factors into the formation
a. Depositional and erosion rates
b. Formation of carbonate dunes and the resulting effects
c. “Stillstand” Phase
