There, temperatures rarely go above 54°, but they can drop down to -94° F. Besides to the chill, the wind usually blows at about 30 to 60 miles per hour. Because of the cold air, there is only about 6-10 inches of precipitation each year. The plants found are small and short to avoid the wind and cold (Whitney S). The Tundra has one tenth of the world’s oil and one fourth of the natural gas in the world. There are also minerals, rare metals, ceramic raw materials, mica, and precious stones (“Natural Resources”). Along the ground lies a layer of frozen ground, called permafrost. The ground is also patterned due to soil movement by melted water. The permafrost and snow melts in summer and makes small ponds all along the ground. (Hu and Bliss). Many animals in the Tundra have adapted by growing thick hair to keep out the cold. The Musk-Ox, for example, has a long undercoat and wolverines have thick fur. Musk-oxen have a sturdy build and stuff themselves with plants during summer to fatten up for winter. Their herds get larger in the winter, and they go on higher ground where the snow blows off the ground. Wolverines have strong jaws to bite through frozen meat. Their feet act as snowshoes and help with climbing. They also hole up in shelter to escape cold and predators (Whitney
