Dry ice (frozen carbon dioxide)
Southern
Mars Polar CapThe southern polar cap is larger and colder. It is composed of carbon dioxide (dry ice) while the northern is mainly water ice (which freezes at a warmer temperature, therefore the dry ice cap in the south is colder).
Mars has a southern ice cap that almost disappears during its summer season. This seasonal disappearance is due to the planet's axial tilt, which causes polar ice to sublimate into the atmosphere as temperatures rise.
The ice caps on Mars are primarily made of water ice, with layers of dust and frozen carbon dioxide. The northern ice cap is larger and consists mostly of water ice, while the southern ice cap is smaller and contains both water ice and frozen carbon dioxide.
Astronomers hypothesize that the southern polar cap of Mars has water ice under the carbon dioxide ice because of radar data that suggests the presence of a thick layer of water ice beneath the surface. Additionally, this hypothesis is supported by theoretical models of Mars' climate and geology.
While the Martian polar caps are mostly water ice, Mars does have a permanent southern polar cap layer of carbon dioxide about eight meters thick.
I think that would be Mars as ice caps are on it. The northern cap is made up of water (Frozen) and the southern cap is made up of frozen gas. I think Mars is mostly made up of rock, I think, I am not a 100% sure.Thanks for reading, guys
rock on mars Maybe a polar cap?
No
Mars has two ice caps. Planum Australe (Southern) and Planum Boreum (Northern). See links for further information.
No - Mars has a polar ice cap but no ice clouds
The ice cap on Mars was discovered by Italian astronomer Giovanni Schiaparelli in the 19th century. He observed the ice cap through his telescope in 1877, and his discovery provided important insights into the polar regions of Mars.
