Definition: the vertical elevation of Earth's surface in response to natural causes.
1. Warping ( epeirogeny): broad, relatively slow, and gentle uplift.
2. Orogeny: severe; associated with earthquakes and mountain building; the result of tectonic-plate collisions. Example: The collision of the Indian and Eurasian plates produced the Himalaya.
3. Isostatic: crustal rebound after the melting of glaciers and ice sheets; ongoing in southern Canada (the Great Lakes) and in the general Scandinavian area today.
