	EO Newsroom: New Images - Tectonic Uplift near Sumatra
		Uplift has raised coastlines out of the water in some areas, while subsidence (sinking) caused the sea to move farther inland in others.
		The epicenter of the magnitude 8.7 earthquake (seventh largest since 1900) of March 28, 2005, was approximately 150 kilometers (90 miles) to the northwest of these images (see map).
		Both the earthquake and uplift were caused by the subduction of the Australia plate underneath the Sunda plate along a boundary called the Sunda Trench (see map).

	NationMaster - Encyclopedia: Tectonic uplift
		The uplift of high mountains at the close of this episode of rapid subduction is therefore a logical after effect of this runaway process.
		These authors puzzle how the tectonic forces could have ceased operating long enough for erosion to have abraded away hundreds to thousands of feet of rock to form flat topography and then be unleashed again to uplift rapidly the entire region by many thousands of feet.
		In this case where the collision is between a continental crust and an oceanic crust, the uplift and creation of the Andes is attributed to the noted sub-duction of the oceanic crust by the ’slab pull’ mechanism.

	Geological Society of America - 2003 Penrose Conference - Tectonics, Climate, and Landscape Evolution
		General acceptance of the principles of the tectonic origin of topography, the increase in erosion rates with relief, and the importance of climate as a modulator between uplift and erosion has evolved into a desire for understanding of the processes, their rates, and the mechanisms of feedback implicit to these principles.
		The landscape response to tectonic deformation, uplift, and horizontal motion.
		In Taiwan, active tectonism and mountain building is evidenced by 4000 m peaks, precipitation rates of several m/yr, and erosion rates as high as 5-10 mm/yr.

	Climate Change 2001: The Scientific Basis
		We define tectonic land movement as that part of the vertical displacement of the crust that is of non-glacio-hydro-isostatic origin.
		Where the tectonics occur in coastal areas, one of its consequences is the changing relationship between the land and sea surfaces as shorelines retreat or advance in response to the vertical land movements.
		With major tectonic activity occurring at the plate boundaries, which in many instances are also continental or island margins, many of the world’s tide gauge records are likely to contain both tectonic and eustatic signals.

	Experimental channel response to tectonic uplift
		We have performed a series of experiments to investigate the relationship between channel geometry and tectonic forcing in steady state landscapes at various uplift rates.
		From this data, channel bed slope was found to be independent of discharge and position on the experimental surface and to increase linearly with uplift rate.
		Channel width, cross-sectional area, and wetted perimeter decrease with increasing uplift rate to a limit value, hydraulic radius and flow depth increase slightly, and flow velocity increases approximately linearly with increasing uplift rate.

	Articles / Impact / Recent Rapid Uplift of Today's Mountains - Institute for Creation Research
		An ongoing enigma for the standard geological community is why all the high mountain ranges of the world—including the Himalayas, the Alps, the Andes, and the Rockies—experienced most of the uplift to their present elevations in what amounts to a blink of the eye, relative to the standard geological time scale.
		This presents a profound difficulty for uniformitarian thinking because the driving forces responsible for mountain building are assumed to have been operating steadily at roughly the same slow rates as observed in today's world for at least the past several hundred million years.
		On the other hand, no mechanical response in terms of uplift during tens of millions of years of tectonic forcing followed by a sudden pulse of uplift poses a serious problem for the uniformitarian framework.

	NOVA Online/Cracking the Ice Age/The Big Chill
		Plateau uplift does, however, have a significant impact on climate, including the diversion of North Hemisphere westerly winds and intensification of monsoonal circulation.
		One mechanism proposed as a cause of this decrease in carbon dioxide is that mountain uplift lead to enhanced weathering of silicate rocks, and thus removal of carbon dioxide from the atmosphere.
		The uplift may have caused both an increase in the global rate of chemical erosion, as well as erode fresh minerals that are rapidly transported to lower elevations, which are warmer and moister and allow chemical weathering to happen more efficiently.

	Evolution of lakes and internally drained basins
		The model accounts for the formation of a water body in topographic basins created by tectonic uplift across a river, which incision capability is approached with a stream power-law, and addresses the notion that, after cessation of tectonic forcing, such lakes are transitory phenomena over geological time scales.
		In addition to geometrical, lithological, and tectonic parameters, the evaporation rate at the lake surface is revealed as a key factor triggering drainage closure (endorheism) and significant lake life extension by preventing outlet erosion.
		The evolution of tectonic lakes has therefore similar dependency on geometrical constraints (initial relief, length of the river, hypsometry of the catchment), lithological parameters (rock erodability), tectonics (uplift rate, duration, and its spatial distribution), and climate (precipitation and evaporation rates).

	Tectonic Forces: Part 13: Discussion
		Under these conditions the orogenic process that is still uplifting the Andes is inevitable.
		In the case where the continent to continent collision occurs, uplift will be by continuous compression due to the inertial force pushing against the upstream side of the moving plate.
		In the latter case (the Maurer Model) the convection currents are considered to have a passive role in tectonic movements.

	TERTIARY UPLIFT AND EROSION HISTORY OF THE BEARTOOTH OVERTHRUST, MONTANA-WYOMING, FROM MODEL TIME-TEMPERATURE PATHS OF ...
		We also used a backstacking apatite FT approach to separate the amount of tectonic uplift (uplift due to tectonic processes) from the amount of uplift that resulted from isostatic rebound (uplift due to removal of overburden by erosion) for each of the uplift phases.
		Our results indicate that 1.9 km of tectonic uplift and ~4.5 km of isostatic rebound occurred during the first phase, and that all differential movement between the upper and lower plates of the Beartooth fault took place during Laramide time.
		If we assume reasonable uplift rates, the second phase of uplift and erosion may have created a regional highland of significant elevation and areal extent by 10-7 Ma that was responsible for regional change in climate, as evidenced by abundant physical and biological evidence in sedimentary basins in the western US.

	Karstgeology: Tower Karst
		The formation of the towers is a combination of tectonic uplift and tropical karst erosion.
		Tectonic uplift matched by karst erosion increases tower heights, as the solution is bigger the valleys.
		If uplift is too slow, the towers are dissoluted and shrink, if it exceeds erosional surface lowering, the towers are raised to hillside locations and the landscape is rejuvenated to form a new generation of dolines and cone karst.

	Deccan uplift
		The uplift of the Sahyadri (Western Ghats), and the attendant uplift of the Konkan Plain to the west of it, are definitely post-Deccan, and offshore sedimentary evidence and apatite fission-track data are consistent with this (Gunnell and Gallagher, 2001; Gunnell et al.
		Pre-eruption uplift is recorded in the Lameta sediments of the Dongargaon Basin of the Nagpur region (Figure 2), where Tandon (2002) recorded a clear “shallowing up” trend from shallow lake deposits to a palaeosol before the terrain was buried by the first Deccan basalt flow.
		Sahyadri uplift is denudational in part (Widdowson and Cox, 1996; Widdowson and Gunnell, 1999), and may also be potentially related also to active eastward flow of the sub-lithospheric mantle relative to the lithosphere as hypothesized by Doglioni et al.

		The earth's surface is covered by seven to nine major tectonic plates and a number of minor plates, or platelets.
		Subduction zones, which are caused when tectonic plates collide, produce the most powerful earthquakes, said Meltzer, because they have long continuous fault lines.
		The earthquake that struck the Indonesian island of Sumatra on Dec. 26 occurred along a subduction zone where the Indian tectonic plate is subducted, or pulled beneath, the Burma tectonic platelet.

	An Online Guide to Sequence Stratigraphy
		Tectonic subsidence is also called driving subsidence and is distinguished from the isostatic effects of sediment and water loads.
		Tectonic subsidence, as its name implies, is driven by tectonic forces that affect how continental lithosphere floats on the asthenosphere.
		During stretching, continental lithosphere is heated, becomes less dense, and tends to uplift from its decreased density (the net effect in a stretched and heated basin may result either in uplift or in subsidence).

	Lecture: Introduction to plate tectonics, Dr. Rodrigue
		Processes of uplift in the earth's crust are the subject of this lecture, now that we've covered the structure of the planet and the materials making up the earth's crust.
		B. The uplift of the earth's crust is very evident at all orders of relief: As you look at the map of the world, you first notice it's divided into oceans (71%) and continents (29%).
		Plate tectonic activity has changed the earth's climates through moving landmasses around, through mountain building (orogeny, which leads to orographic precipitation, rainshadow deserts, and higher, cooler climates on mountains and plateaux), and through diverting warm ocean currents.

		Tectonic uplift of the range relative to the Denver Basin exceeds 6 km.
		Tectonic models that involve vertical uplift on faults whose dip increases with depth on both flanks of the range are not compatible with the geologic data, nor are models that treat the range as a large flower structure on a wrench fault system.
		Given an average width of ~65 km, the depth at which the thrusts must flatten to produce the homocline on the east flank of the range is ~45 km, which is the approximate depth of the Moho.
