The polar ice caps on mars are mainly CO2 ice, frozen carbon dioxide. This is sometimes called `dry ice` on earth as it goes directly from gas to solid form with no liquid phase at normal pressures.

Mars has polar ice caps and two moons, named Phobos and Deimos. The ice on Mars is primarily made up of water ice and carbon dioxide ice, and the two moons are irregularly shaped and thought to be captured asteroids.


What is mar's largest polar cap?

Mars' largest polar cap is the northern polar cap, known as the North Polar Ice Cap. It is made up of water ice and carbon dioxide ice, covering an area roughly equivalent to the size of Greenland on Earth.


What planet has ice caps that change in size with the seasons other than earth?

Mars has polar ice caps that change in size with the seasons. The polar ice caps on Mars are predominantly made of water ice and carbon dioxide ice (dry ice) and they grow and recede with the planet's changing seasons.


Planet that has polar ice caps?

Both Mars and Earth have polar ice caps, cooler areas with reduced exposure to the sun. Those on Earth are mainly made from water ice, while those on Mars are mainly made from frozen carbon dioxide.


Of what are Mars' ice caps made?

Mars' ice caps are predominantly made up of water ice, with some layers also containing a mix of frozen carbon dioxide, also known as dry ice. The white polar caps are primarily composed of water ice, while the seasonal polar caps are a combination of water ice and frozen carbon dioxide.


Which planet has a thin atmosphere and polar caps?

Mars has a thin atmosphere and polar caps made of a combination of water ice and dry ice (frozen carbon dioxide). The atmosphere on Mars is about 100 times thinner than Earth's atmosphere.


What planet has polar ice caps?

Mars has polar ice caps at its north and south poles. These ice caps are primarily composed of water ice and carbon dioxide ice. The polar ice caps on Mars play a significant role in the planet's climate and atmospheric composition.


How many ice caps does Mars have?

Mars has two ice caps. Planum Australe (Southern) and Planum Boreum (Northern). See links for further information.


Which polar cap on Mars is larger and colder?

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).
