Pinnacle Overlook in Cumberland Gap National Historical Park, Great Smoky Mountains National Park, North Carolina. Both of these processes helped give birth to the Appalachians. You see rocks cut by numerous faults that consist of basalt with evidence of eruption in the ocean, deep-water chert, mudstone, and sandstones with abundant volcanic material. Why do different substances have different properties? Suppose that a professional baseball pitcher hurls a baseball (m=155 g) with a speed of 100 mi/h (v1=44m/s)\left(v_{1}=44 \mathrm{m} / \mathrm{s}\right)(v1=44m/s) at a wall that is securely anchored to the Earth, and the ball bounces back with little loss of kinetic energy. Around 480 million years ago, an oceanic plate was getting subducted under the eastern part of North America, producing some volcanic mountains there. What's causing this uplift? Our own beautiful landscapes of East Tennessee and western North Carolinapart of the Appalachian Mountains, whose genesis was more than 250 million years agois one focus of the exhibit; the other is the striking and rugged Himalaya Mountains, the much younger and still-rising result of tectonic movements, the global effects of which we learn The Appalachians formed about 400 million years ago. We have a number for the age of the universe (about 13.8 Gyr), and the age of the Appalachians (0.48 Gyr) is about 3% of that number.

His work has won him several awards, including two regional Edward R. Murrow awards, one national Murrow, and the Overseas Press Club of America's award for best environmental reporting in any medium. crustal thickening over million of years has produced a thick crust that stands high due to Isostacy, a strike-slip fault that forms the boundary between tectonic plates. To a geologist, the rocks of the Appalachian Mountains reveal a billion-year story of violent continental collisions and the subsequent mountain building, erosion, deposition and/or volcanism that came with.
