During the summer, when the polar temperatures reach as high as 85–90 K, carbon dioxide sublimates and migrates to the opposite pole and to the equatorial regions, giving rise to a type of carbon cycle.
Durante o verán, cando a temperatura polar acada os 85–90 K, o dióxido de carbono sublimase e migra ó polo oposto e as rexións ecuatoriais, establecendo así un tipo de ciclo do carbono.
