• The Arctic fox is about 10 -16 inches long and weighs about 6-12 pounds. It is about the size of an ordinary domesticated house cat. It has short legs a long bushy tail that it uses as insulation by wrapping it around itself when sleeping. Its long hair is white in the winter, and "blue" or gray in the summer. Its head has a stubby muzzle, small ears, and large eyes. Its feet are lined with fur, which helps it conserve heat. The Arctic fox has adapted a stealthy movement due to its predatory nature.

• Caribou moss grows in arctic and northern regions around the world. It grows on the ground and on rocks. It looks like a foamy, gray-green spongy mass, and grows to be 1 to 4 inches high. The stems, or stocks, are hollow, and branch out many times. Although it is called caribou moss, it is actually a lichen. chlorophyll which can make food. Each has something the other needs. This is called a symbiotic relationship. Lichen can make food when the temperature gets very low and there is little light. The tissues of lichens aren't easily damaged by frost. This makes it a great plant for the tundra.

• Did you know that the Arctic Tundra is the world's youngest biome? It was formed 10,000 years ago. Located at latitudes 55° to 70° North, the tundra is a vast and treeless land which covers about 20% of the Earth's surface, circumnavigating the North pole. It is usually very cold, and the land is pretty stark. Almost all tundras are located in the
Northern Hemisphere. Small tundra-like areas do exist in
Antarctica in the Southern Hemisphere, but because it is much colder than the Arctic, the ground is always covered with snow and ice. Conditions are not right for a true tundra to form. Average annual temperatures are -70°F (-
56°C).

• Oil and gas development-->global warming: only 6 months left of natural oil; permafrost melts and tundra ecosystems collapse: as permafrost begins to decay, (dead plants) release more carbon dioxide and accelerate global warming

• Ozone depletion in North/South poles: stronger
UV rays destroy tundra
• Air pollution: poisons lichen, which feeds many animals
• Buildings and roads: put heat on permafrost and cause it to melt
• Invasive species: push aside native vegetation and reduce diversity of plant cover

• The tundra is the coldest and the driest of all the biomes on Earth. This biome lies above the
Arctic Ocean in the world's highest northern latitudes. The tundra covers about one fifth of the land surface found on Earth. These low swampy plains are found in Northern Europe,
Siberia, Northern most part of North America, and a few places in the southern hemisphere

• Deciduous Forest Biome

• Plant. The American Beech tree grows in the southern and eastern parts of the United States. It grows in deciduous forests all over Maine and northern Massachusetts. It grows best in deep, rich, moist, well-drained soils.
• Animals. The Bald Eagle is a large fierce looking bird. It's name in Latin means "the sea eagle with a white head". It is the national symbol of the United States of America.
Benjamin Franklin had suggested that the national symbol be the Wild Turkey, because the Bald Eagle was "a bird of bad moral character", but he was outvoted. Today it is seen on many things in the United States, such as money, seals, and other patriotic symbols.
