The 2,200-mile (3,540-kilometer) pathway shares its name with a mountain range whose dense forests and rocky slopes are a magnet for those who love the outdoors. Compared with the Rocky Mountains of western North America, which have 50 plus peaks over 14,000 feet in elevation, the Appalachians are rather modest in height. The Himalayas and Tibet are the archetypical example of a(n) ________ mountain belt. Southwestern North America contains a large area called the Basin and Range province. First is isostasy: the bigger a mountain gets, the more it weighs down its tectonic plate, so it sinks lower. While you may think of " Appalachia " as a region of the southern United States, the full Appalachian Mountains have a massive (not to . A) The Appalachian Mountains are younger and younger mountains tend to be more weathered. 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 Appalachian Mountains may have once been as lofty as the Himalayan-Tibetan Mountain belt is today. We should also point out that tectonic collision is not the only way to make a mountain. Every other Friday on Morning Edition NHPRs Sam Evans-Brown tracks down answers to questions about the environment and outdoors for our listeners in a segment we call Ask Sam.. All the continents move on continental plates, but Indian subcontinent was moving at a much greater force and sleep. You are walking on the beach along the south-coast of Alaska. C) The Appalachian Mountains are older and thus have become more worn down. Alas, the Appalachians eventually stopped growing. What type of stress when rock is pulled in opposing directions?

Why are they not this high now? These moving tongues of ice stripped topsoil, ground and polished certain peaks, and elsewhere scattered rock debris and random boulders, all the while driving plants and animals farther south where they could survive. Paleoelevationthe measuring of ancient mountainsisn't an exact science, but from clues in the rock (levels of sediment, size of wrinkly synclines and anticlines, fossils, oxygen isotopes in minerals) it's possible to guess at the altitude of mountains that aren't there anymore. The Appalachian Mountains, which range from Canada down through the southeastern United States, started forming about 480 million years ago. So, in not-exactly-correct laymans terms, the way they melt tells us how how deep the mountains roots were, which gives us a more precise estimate of how high they must have been. Why are they not this high now? To the east lie the Blue Ridge Mountains and Piedmont, composed primarily of metamorphic and igneous rocks.
