Summary
[edit]DescriptionMartian CO2 gas venting.jpg |
English: Schematic sketch of the CO2 geyser hypothesis. Martian south polar layered terrain is overlain by seasonal ice of ~1 m in thickness. Penetration of sunlight to the base of the seasonal deposit causes sublimation from the bottom, leading to a buildup of pressurized CO2 gas. The gas eventually bursts out, entraining dust and leading to the dark fan-shaped deposits. Repeated outbursts from year to year erode the underlying polar layered deposits, leading to the development of "Martian spiders".
Polski: Schematyczny szkic hipotezy gejzera CO2 Marsjańskie czapy polarne są przykryte przez suchy lód grubości ~ 1 m. Przenikanie światła słonecznego do podstawy podłoża poprzez taflę lodu (na wiosnę) powoduje sublimację CO2 od dołu, co prowadzi do tworzenia się gazowego CO2 poddawanemu coraz to większemu ciśnieniu. Gaz w końcu wybucha, porywając piasek i kurz, co prowadzi do tworzenia się na powierzchni lodu ciemnych osadów, najczęściej wachlarzowatych. Powtarzające się wybuchy z roku na rok, zaburzają/rozwijają podstawowe polarne warstwy osadowe, co prowadzi do rozwoju "marsjańskich pająków". Romkur 21:32, 16 August 2013 (UTC) |
