Notwithstanding this, the thickest part of the skin of the giraffe is near that seen in other huge African warm-blooded creatures, for example, the white rhinoceros which has a skin thickness around 25 mm (Shadwick et al., 1992), the African elephant with a skin thickness near 20 mm . Gestation lasts 235 days and cubs are born in January to early February. Polar Bear Adaptations: Low surface area to volume ratio (anatomical) - Compared to other species of bears, polar bears have small extremities, proportionally shorter legs and a stockier build. Skeleton was found in 1887 in a swamp located between Champaign and how thick is the thickest part of bear glacier. The snow and firn are thickest at the top of the glacier and thin down-glacier to zero at the equilbrium line. The flow of alpine glaciers is primarily controlled by the slope of the land beneath the ice (Figure 16.10). The largest of the Juneau Icefield Glaciers, Taku Glacier is a tide water glacier. In 2017, park staff installed a camera to monitor this source lake to better understand the dynamics of this cycle and reoccurring event. Pressure is great enough to melt the base of the glacier and it begins to move. The IKONOS satellite took this picture on August 8, 2005, capturing the glacier emptying into a nearby lake. Sea ice forms when the surface of the ocean freezes during fall and winter: air temperatures in the wintertime Arctic average -30oC (-22oF). The second photograph dates from August 11, 2005. Latitude, topography, and global and regional climate patterns are important controls on the distribution and size of these glaciers.
