Summary

Description

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)

(Reusing this file)
This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
Public domain Uploader asserts that this file has been released into the public domain by the copyright holder, its copyright has expired, or it is ineligible for copyright.

Note: This template is missing the primary license justifying the original PD claim. Please add a second parameter specifying the primary license, like {{PD-scan|PD-old-100}}, {{PD-scan|PD-US-expired}} or {{PD-scan|PD-USGov}}.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.

Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
