Lifted fault-block geology Tilted fault-block formation in the Teton Range. Fault-block mountains often result from rifting, an indicator of extensional tectonics. These can be small or form extensive rift valley systems, such as the East African Rift zone. Death Valley in California is a smaller example.
When a fault block is raised or tilted, a block mountain can result. [17] Higher blocks are called horsts, and troughs are called grabens. A spreading apart of the surface causes tensional forces. When the tensional forces are strong enough to cause a plate to split apart, it does so such that a center block drops down relative to its flanking ...
Mount Everest, Earth's highest mountain. A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock.Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (980 ft) above the surrounding land.
The "Pennsylvania Salient" in the Appalachians appears to have been formed by a large, dense block of mafic volcanic rocks that became a barrier and forced the mountains to push up around it. 2012 image from NASA's Aqua satellite.

The mountains are known as the Himālaya in Nepali and Hindi (both written हिमालय), Hinvāl (हिंवाळ) in Garhwali, Himāl (हिमाल) in Kumaoni, the Himalaya (ཧི་མ་ལ་ཡ་) or 'The Land of Snow' (གངས་ཅན་ལྗོངས་) in Tibetan, also known as Himālaya in Sinhala (written as ...
Tilted block faulting, also called rotational block faulting, is a mode of structural evolution in extensional tectonic events, a result of tectonic plates stretching apart. [ 1 ] [ 2 ] When the upper lithospheric crust experiences extensional pressures, the brittle crust fractures, creating detachment faults . [ 3 ]
The most isolated major summits of Europe by topographic isolation are located in the European continent and its tectonic and geographic boundaries.This includes major mountain peaks of fold and fault-block mountains, and also volcanoes, [1] located not only in the European Mainland, but also those located on lands and islands on the limits of Europe, like the North Atlantic Ocean islands of ...
The Aravalli Range (also spelled Aravali) is a mountain range in Northern-Western India, running approximately 670 km (420 mi) in a south-west direction, starting near Delhi, passing through southern Haryana, [1] Rajasthan, and ending in Ahmedabad Gujarat.
