The predominant climate zone in the Arctic regions is the "polar climate." Characterized by long, harsh winters and short, cool summers, the polar climate features low temperatures and significant snowfall. Vegetation is sparse, mainly consisting of mosses, lichens, and some hardy shrubs. The region experiences prolonged periods of darkness in winter and endless daylight in summer, resulting in unique ecological conditions. The extreme cold and ice cover also play critical roles in the habitats of Arctic wildlife, impacting their behaviors and adaptations.
