What is the geographic significance of the pediment region of Georgia

Georgia is crossed by five distinct physiographic provinces, based on similarities in land formations, elevation, rocks and minerals, soil, and other characteristics. They are the 1) Coastal Plain, 2) Piedmont, 3) Blue Ridge, 4) Ridge and Valley, and 5) Plateau. You can see this regions marked in the accompanying maps; below is a description of each region.

Coastal Plain

For more on the Lower Coastal Plain, see the New Georgia Encyclopedia.

Georgia's largest geographical region is the Coastal Plain; it covers approximately 60 percent of the state, from the Atlantic Ocean to the Fall Line. In prehistoric times, this area of what is now Georgia was covered by ocean. Ocean waves slowly wore down hills and other land formations as they advanced inland. As time passed, countless numbers of seashells and other remains of ocean life sank to the ocean floor. Tightly packed, they eventually became beds of soft rock called limestone. Over time, rivers and streams deposited large amounts of soil, clay, and rock that had eroded from the hills and mountains to the north into the ocean. This eventually caused thousands of feet of sediment - or settled deposits - to cover the ocean floor.
