WebDuring the Martian summer, the caps recede but never completely disappear. The permanent cap at the Martian north pole is formed not of dry ice, but of ordinary water ice. The residual north polar cap has been measured to be about 1000 km in diameter. Measurements from Global Surveyor indicate a thickness of about 3 km for this ice cap. WebFor example, Earth's polar caps are mainly water ice, whereas Mars 's polar ice caps are a mixture of solid carbon dioxide and water ice. Polar ice caps form because high-latitude regions receive less energy in the form of solar radiation from the Sun than equatorial regions, resulting in lower surface temperatures.

The planet Mars has two permanent polar ice caps. During a pole's winter, it lies in continuous darkness, chilling the surface and causing the deposition of 25–30% of the atmosphere into slabs of CO2 ice (dry ice). When the poles are again exposed to sunlight, the frozen CO2 sublimes. These seasonal actions … See more Research based on slight changes in the orbits of spacecraft around Mars over 16 years found that each winter, approximately 3 trillion to 4 trillion tons of carbon dioxide freezes out of the atmosphere onto … See more The bulk of the northern ice cap consists of water ice; it also has a thin seasonal veneer of dry ice, solid carbon dioxide.
