The extra resistant rocks type ridges, and the valleys are underlain by weaker ones. These fold belts generally embody segments where layers of older rocks have been thrust or pushed up and over younger rocks. Bearhat Mountain above Hidden Lake on a crest of the Continental Divide in Glacier National Park, Montana. Mountain, landform that rises prominently above its environment, usually exhibiting steep slopes, a comparatively confined summit area, and considerable local aid. Mountains typically are understood to be bigger than hills, however the term has no standardized geological which means.

On a big scale, there is a clear orientation of such ranges, however within them the landforms are controlled more by the variations in erosion than by tectonic processes. These are metamorphic and igneous rocks that typically solidified at depths of several kilometres or more and that are extra resistant to erosion than the sedimentary rocks deposited on high of them.
- All are at least 14,000 feet (4,300 meters) excessive.The ibex, a wild goat, and the goatlike chamois are extremely nimble within the craggy landscape.
- In the alpine areas, one can find a few of the most iconic flowers of the Alps, including edelweiss, alpine rose, heather, and gentian.
- The mountain hare and the ptarmigan, a grouse, take on white coats for winter.
- Several nationwide parks within the Alps protect the native fauna.
- In the higher altitudes, dense evergreen forests of fir, larch, and pine dominate the panorama.
These crystalline terrains sometimes comprise the best peaks in any mountain belt and include the very best belt in the world, the Himalayas, which was shaped by the thrusting of crystalline rocks up onto the floor of the Earth. The nice heights exist due to the resistance of the rocks to erosion and because the rates of continuing uplift are the best in these areas. The topography not often is as regularly oriented as in fold and thrust belts. fold belts, as, for example, within the Valley and Ridge province of Pennsylvania within the japanese United States.
In most cases, they are present in elongated ranges or chains. When an array of such ranges is linked together, it constitutes a mountain belt.
