Tectonic uplift is the portion of the total geologic uplift of the mean Earth surface that is not attributable to an isostatic response to unloading. Whereas isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and underlying mantle, and flexural support due to the bending of rigid lithosphere.
It is also good to take into consideration the effects of denudation (processes that wear away the earth's surface). Within the scope of this topic, uplift relates to denudation in that denudation brings buried rocks closer to the surface. This process can redistribute large loads from an elevated region to a topographically lower area as well – thus promoting isostatic response in the region of denudation (which can cause local bedrock uplift). The timing, magnitude, and rate of denudation can be estimated using pressure-temperature studies.

Steady state topography development along a vertical cross section. Calculated assuming constant uplift rate at the center (1 mm/yr stopping at t=5 Myr, between x=-50 and +50 km) and a 1D stream power law erosion model. River erosion is proportional to slope and water discharge (constant precipitation rate over the entire profile). The dashed line marks the topography that would form in absence of erosion. Note the steady states reached before 5 Myr (about 3 km max. topography) and at ~8 Myr (flat topography). Note also that at equilibrium, the model correctly predicts uplift rate=erosion rate at every location, and that in the end, total erosion = total uplift Calculated under Linux with the program tAo by Garcia-Castellanos (2007, EPSL).

How to demonstrate the way geologic forces create conditions where uplift or mountain building takes place. In this instance a wax model of strata is created and subjected to powerful compression forces which results in uplift of parts of the wax structure.
Ladakh is a region of Jammu and Kashmir,in the northernmost state of the Republic of India. It lies between the Kunlun mountain range in the north and the main Great Himalayas to the south, inhabited by people of Indo-Aryan and Tibetan descent. It is one of the most sparsely populated regions in Jammu and Kashmir. The largest town in Ladakh is Leh. It is one of the few remaining abodes of Buddhism in South Asia, including the Chittagong Hill Tracts, Bhutan and Sri Lanka; a majority of Ladakhis are Tibetan Buddhists and the rest are mostly Shia Muslims.

Modelled topography of the eastern Australian highlands since 150 million years ago. The model is based on a coupled plate tectonic-mantle convection model run on the Australian high performance computer Raijin (http://nci.org.au/systems-services/national-facility/peak-system/raijin/). The model shows that the time-dependent interaction of plate motion with mantle downwellings and upwellings accounts for the broad pattern of margin uplift phases. Initial dynamic uplift of 400-600 m from 120-80 Ma was driven by the eastward motion of eastern Australia’s margin away from the sinking eastern Gondwana slab, followed by tectonic quiescence to about 60 Ma in the south (Snowy Mountains). Renewed uplift of ~700 m in the Snowy Mountains is propelled by the gradual motion of the margin over the e...

The interaction between "erosion and tectonics" has been a topic of debate since the early 1990s. While the tectonic effects on surface processes such as erosion have long been recognized , the opposite has only recently been addressed. The primary questions surrounding this topic are what types of interactions exist between erosion and tectonics and what are the implications of these interactions. While this is still a matter of debate, one thing is clear, the Earth's landscape is a product of two factors: tectonics, which can create topography and maintain relief through surface and rock uplift, and climate, which mediates the erosional processes that wear away upland areas over time. The interaction of these processes can form, modify, or destroy geomorphic features on the Earth’s su...
We continue a series on What Every Adventist Scientist Should Know. This fifth week we review the data on rates of erosion of continents and uplift of mountains. 1.

Review and Herald Publishing. 2. For a broad discussion of the time issue see Chapter 5: So Little Time for Everything, in Roth AA. 2007. Science Discovers God. Autumn House, Review and Herald. 3.

New Zealand : Great Walks New Zealand is an island country in the southwestern Pacific Ocean. The country geographically comprises two main landmasses – that of the North Island, or Te Ika-a-Māui, and the South Island, or Te Waipounamu – and numerous smaller islands. New Zealand is situated some 1,500 kilometres (900 mi) east of Australia across the Tasman Sea and roughly 1,000 kilometres (600 mi) south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long isolation, New Zealand developed a distinctive biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volc...
Dynamic geochronological constraint derived from fault-bounded slivers of high grade crystalline rocks in the footwall to New Zealand’s Alpine Fault system captures the early evolution of this plate-bounding structure during the late Oligocene and early Miocene. This record reveals a telling insight into the way structurally complex crustal fabrics respond to major change in tectonic forcing. Initial development of a transform plate boundary through the central South Island of New Zealand saw deformation dispersed across a broad domain of inherited fault systems and complex crustal architecture. Local transpressional kinematics imposed on non-optimally aligned structures during this period produced isolated domains of rapid uplift and corresponding orogenic-scale topography. Sequential aba...
