'''Depresija''' (ili ulegnuće) je dio [[Zemlja (planet)|zemljine]] površine jdjsowkejdj |
|||
Uzroci stvaranja depresija su mnogobrojni i vrlo različiti. |
|||
Depresije su česte u [[sušno područje|sušnim područjima]] [[Zemlja|Zemlje]]. Najniže dijelove takvih depresija, ako nemaju mogućnost istjecanja vode, pokrivaju [[slana močvara|slane močvare]] ili [[slano jezero|slana jezera]]. Iste takve depresije, ako se nalaze u vlažnim područjima, ispunjavaju [[jezero|jezera]]. Ako je dno takvog jezera ispod razine [[more|morske]] površine, riječ je o '''kriptodepresiji'''. |

'''Depression''' in [[geology]] is a [[landform]] sunken or depressed below the surrounding area. Depressions may be formed by various mechanisms, and may be referred to by a variety of technical terms. |
|||
*A [[Blowout (geology)|blowout]] is a depression created by [[wind]] [[erosion]] typically in either a [[desert]] [[sand]] or post-glacial [[loess]] environment. |
|||
*A [[graben]] is a down dropped and typically linear depression or basin created by [[rifting]] in a region under tensional tectonic forces. |
|||
*An [[impact crater]] is a depression created by an impact such as a [[meteorite]] crater. |
|||
*A depression may be an area of [[subsidence]] caused by the collapse of an underlying structure. Examples include [[sinkhole]]s in [[karst topography]], [[caldera]]s or [[maar]]s in volcanic areas, or [[Kettle (geology)|kettles]] in [[Glacier|glaciated]] terraines. |
|||
*A depression may be a region of tectonic downwarping typically associated with [[subduction zone]]s and fore-arc and back-arc [[basin]]s associated with [[island arc]]s. These typically result in [[sedimentary basin]]s as they fill with [[sediment]] from adjacent island arc or continental [[volcanism]] and uplift. |
|||
*A depression may result from the weight of overlying material such as an ice sheet during continental [[glaciation]] which is subsequently removed resulting in a basin which slowly [[Post-glacial rebound|rebounds]]. |
|||
* A depression may be a [[pothole]] - either a simple roadway depression or a [[fluvial]] erosional depression in a [[river]] [[streambed]], or area affected by coastal water currents. |
|||
One of many impressive depressions is the [[Great Rift Valley]] of East [[Africa]]. Perhaps even more impressive is the [[Atlantic Ocean]] basin. |

Najdublje takve depresije na Zemlji su [[Bajkalsko jezero]], [[Kaspijsko jezero]], [[Mrtvo more]], [[Jezero Tanganjika]], [[Dolina smrti]] i [[Eyre (jezero)|Eyre]] (Australija). |
