Erosion of mountains massifs can create a pattern of equally high summits called summit accordance. [73] It has been argued that extension during post-orogenic collapse is a more effective mechanism of lowering the height of orogenic mountains than erosion. [74] Examples of heavily eroded mountain ranges include the Timanides of
It is formed by the more erosion-resistant sandstones of the Dakota Formation protecting the softer, less erosion-resistant strata of the Morrison Formation. Hogsback up Bald Mountain, in the Adirondacks of New York. Dinosaur Ridge is a well known hogback that is part of Morrison Fossil Area National Natural Landmark within Morrison, Colorado.
Escarpment face of a cuesta, broken by a fault, overlooking Trenton, Cloudland Canyon State Park, and Lookout Mountain in the U.S. state of Georgia. An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations.
In addition to surface erosion, badlands sometimes have well-developed piping, which is a system of pipes, joints, caverns, and other connected void spaces in the subsurface through which water can drain. However, this is not a universal feature of badlands. For example, the Henry Mountains badlands show very little piping. [2]
The Flatirons near Boulder, Colorado, is both an example of these landforms and the source of their name. Other well-developed flatirons are found in the eastern Uinta Mountains in northwestern Colorado, [6] the Waterpocket Fold in Capitol Reef National Park, the Superstition Mountains near Phoenix, Arizona, and on the flanks of the Marathon Uplift in west Texas.
Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
Many of the intermontane plains, occurring mostly in the north, appear to be heavily aggraded with mountain waste. Others, mostly in the south, are valleys also heavily aggraded by mountain erosion. The structure of the region previous to faulting was dependent on long antecedent processes of accumulation and deformation and the surface of the ...
The Matterhorn, a classic example of a pyramidal peak. A pyramidal peak, sometimes called a glacial horn in extreme cases, is an angular, sharply pointed mountain peak which results from the cirque erosion due to multiple glaciers diverging from a central point. Pyramidal peaks are often examples of nunataks.
