Antarctica receives very little rainfall throughout the year. Some sources claim that the average rainfall received per year is approximately 35-50 centimeters. This region is considered as the coldest, windiest and highest continent across the globe. Ninety eight per cent of Antarctica's, which is 14.3 million square kilometers, is covered by an enduring sheet of ice. This approximately covers 90% of the world's ice and nearly 70% of the Earth's fresh water. From the incline of the Antarctic isthmus south to 68°S, standard monthly temperatures surpasses 0°C for 3-4 months of summer, and hardly ever fall below -10°C during winter. This neck of land is bisected by the Antarctic Circle, where just about 2 hours of twig daylight occur during winter days, and somewhere close to 24 hours of sunlight throughout summer.
