In a 2-page paper (double spaced – 12pt font) research the rich Geological History of how the Appalachian Mountains were built and eroded away over the past ≈500 million years.  Provide detail into how the Gap itself formed (specifically from what geological time period & process) and how the layers in the photo below depict the differences that are seen now-a-days and how they relate to the paleo-environment.  The paleo-environment discussion should include the absence of types of ocean forming strata, as well as other strata that was uplifted during this time. Use at least 2 of the 4 sources provided below to provide scientific relevance of this topic.  Please site references correctly, and DO NOT plagiarize (will result in automatic zero). Paper should be organized as follows: Introduction, Literature Review, Discussion, Conclusion, References.
