Webbpolar caps are related to the Martian climate history, the seasonal polar caps are related to the current climate and circulation. By understanding the sublimation and condensation of carbon dioxide and water, seasonal change and atmospheric circulation of current and future climate of Mars will be better known. High resolution images taken with NASA's Mars Global Surveyor show that the northern polar cap is covered mainly by pits, cracks, small bumps and knobs that give it a cottage cheese look. The pits are spaced close together relative to the very different depressions in the south polar cap. Visa mer 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). … Visa mer Both polar caps show layered features, called polar-layered deposits, that result from seasonal ablation and accumulation of ice together with dust from Martian dust storms.
