The Coastal Plain of Georgia stretches from the fall line to the Atlantic Ocean, covering 35,650 square miles (60% of the state). The Coastal Plain was once a sea floor and is composed mainly of unconsolidated sediments with little hard rock at the surface. Coastal Plain sediments originated in the Piedmont and even in the mountains beyond and have been deposited over thousands of years. Near the fall line the Coastal Plain can be highly dissected but it becomes nearly completely flat closer to the coast. The current soils of the Coastal Plain tend to be sandy, a result of prehistoric oceans advancing and retreating across them. Prehistoric wave action dissolved and reduced soils to the sturdiest of substrates, quartzite or sand.
