2General Description - Location Located on in the Northern HemisphereCovers about 1/5 of the Earths land surfaceArctic Tundra is a place of barren land, that sometimes is grasslandThe sun barely shines in the winter and almost never sets in the Summer because of the Earth’s Tilt
3General Description Temperature Temperature is always cold – Never reaches above 25 degrees CelsiusSummer only lasts for 6-10 weeks, with a growing season of 50 daysAvg Yearly Temp is Degrees FAvg. Temps for Fairbanks, AK and Nuuk, Greenland
4General Description - Rainfall Avg. yearly rainfall for Fairbanks AK, and Nuuk, GreenlandNot much rainfall at all, around 6-10 inches per yearMost Rainfall occurs in late summer
5Polar Bears and the Arctic Wolf are the top predators Food WebPolar Bears and the Arctic Wolf are the top predatorsPrimary Photosynthesizes: Arctic Moss, Bearberry, Caribou Moss, Diamond-leaf WillowWho Eats the Plants: (Herbivores) Musk Ox, Arctic Hare, Lemmings, Caribou, and PikasWho eats the animals that eat the plants: (Carnivores) Arctic Fox eat the Pikas along with the Lemmings. Snowy Owl, Coyotes and River Otters.Who is a carnivore: (Scavenger) (eats anything) Ermine, Arctic Fox and Wolverines. Wolverines may be small but they are very strong. They can catch animals that are much bigger than themselves to eat.Top Predator: Arctic wolf and the polar Bear along with Arctic Fox along with Coyotes.
6AdaptationsErmine: It’s claws allow it to dig easily into the ground. The coat of the Ermine changes with the seasons to camouflage it from its predatorsPolar Bear: Has two layers fur to keep it warm in the harsh climateCaribou: has large spreading hooves to support them in the snow in the winter and the marshy tundra in the summer.
7More Animal Adaptations Snowy Owl: Dense white feathers to keep them warm and also to provide camouflage in the snowRock Ptarmigan: seasonally camouflaged to prevent it from being attacked by predators.
8Plant AdaptationsBearberry: Low growing plant that can stay out of wind chill and also has leathery leaves to protect it from the cold
9Geological Feature Permafrost Ground that is frozen for at least two yearsIs formed when water is frozen within the groundPermafrost can reshape the land thought slight thawing and freezingCan stay frozen all summer longProcess when melting The sun heats the topsoil, but is not hot enough to heat up permanently frozen ground. As a result there are massive swamplands that slosh above the frozen ground.A jackhammer must be used to dig into the soil
