To really understand the geology of Shenandoah National Park, we first have to look at the park's setting. One is old the other young. A look at rocks exposed in today's Appalachian Mountains reveals elongate belts of folded and thrust faulted marine sedimentary rocks, volcanic rocks and slivers of ancient ocean floor - strong evidence that these rocks were deformed during plate collision. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The supercontinent Rodinia was created around 1 billion years ago as a result of this mountain-building event in Grenville Orogeny. Tucker is a suburb of Atlanta and is situated at the southern end of the Appalachian Mountains. The collision created the Appalachian Mountains. The Appalachian mountains that we see today were formed approximately 260 million years ago, though the oldest rocks exposed at the surface are over 500 million years old. The ocean con tinued to shrink until, about 270 million years ago, the continents that were ances tral to North America and Africa collided. Appalachian Mountains, North American highland system that extends for almost 2,000 miles from the Canadian province of Newfoundland and Labrador to central Alabama in the United States, forming a natural barrier between the eastern Coastal Plain and the vast Interior Lowlands of North America.

Name the 3 major orogenic events that formed the Appalachian mountains. Raindrops and flowing water shape the mountains by dislodging sediment from the slope and transporting material in streams and rivers. The collision of tectonic plates can also create mountainous foothills in regions adjacent to it, referred to as a fold and thrust belt. The two types of rock that characterize the present Appalachian ranges tell much of the story of the mountains' long existence. Very old. The southern Appalachian mountain-building episode, according to Dr. J. William Miller, Jr., assistant professor of geology at the University of North CarolinaAsheville, consisted of a series of at least three such events which began 15 million centuries ago and ended about 2.3 million centuries ago at the end of the Paleozoic time.
