→Orogenic uplift: water gaps |

Line 29:
The [[Colorado Plateau]] which includes the [[Grand Canyon]] is also the result of broad tectonic uplift followed by river erosion.<ref>Karlstrom, K.E., et al., 2012, ''Mantle-driven dynamic uplift of the Rocky Mountains and Colorado Plateau and its surface response: Toward a unified hypothesis,'' Lithosphere, v. 4, p. 3–22 [http://lithosphere.gsapubs.org/content/4/1/3.abstract abstract]</ref>
When mountains rise slowly, either due to orogenic uplift or other processes (e.g., rebound after glaciation), an unusual feature known as a [[water gap]] may occur. In these, erosion from a watercourse such as a river occurs faster than mountain uplift, resulting in a gorge or valley that runs through a mountain range from low-lying country on one side to similar country on the other. Examples of such water gaps include the [[Manawatu Gorge]] in New Zealand and the [[Cumberland Narrows]] in Maryland, United States.
