The Appalachians have weathered and eroded away over the past hundreds of millions of years, leaving only remnants of the mountain system that once reached record heights. Why are they not this high now? The second is called the glacial buzzsaw: the taller and colder a peak, the faster snow and ice will wear it away. Mitchell, Brooks. Apart from the question of a tectonics slowdown, the idea of the supercontinent blanket raises another possibility: that excess heat building underneath could have weakened the overlying rocks. The restless tectonic plates of modern Earth shift continuously, in a slow-motion dance that reshapes the surface of our planet. It includes the St. Lawrence River valley in Canada and the Kittatinny, Cumberland, Shenandoah, and Tennessee valleys in the United States; the latter is the site of the world-famous Tennessee Valley Authority (TVA), a government agency for natural resource conservation, power production, and regional development.
