Transcript of Tundra biome

The Tundra The average temperature in the tundra is about -30o-20o Fahrenheit for winter and between 30 and 50 degrees Fahrenheit in the summer. The average precipitation is 6 to 10 inches per year similar to that of a desert. Snow drifts and permafrost are abundant in the Tundra. Some useful clothes and supplies to have in the tundra are: a heavy coat, snowshoes, snow pants, wind protection, hats, gloves, and scarves.
In the summer it will only reach up to 50 degrees Fahrenheit. It is buggy and there is almost 90 days of full sun, so some sunscreen and sunglasses may be beneficial. The biggest threat to the tundra is global warming and the Green House effect. The Greenhouse effect is the relationship between the radiation, earth, and the gasses in the atmosphere. The radiation is a type of heat. When the sun omits radiation into the earth, the earth absorbs some, and reflects the rest. The gasses in the atmosphere and the ozone trap the radiation and send it back to the earth. Another problem for the tundra is that one third of the carbon found in soil is trapped inside of the permafrost. Because of global warming, the permafrost is thawing and releasing carbon dioxide. Hiking and Backpacking
The Arctic tundra country demands to be traveled on by foot along the gravelly roads, and past lakes and snowy areas. Wildlife Viewing!
The tundra is home to very unique animals that are interesting to view because of how unique and interesting they are. Some of the animals are grizzly bears, gray wolves, and wolverines. Among others are polar bears, golden eagles, ravens, camouflaged ptarmigan, caribou, and mountain goats. See the rare needle-leaf forests in Canada. It is the largest biome in the world! The taiga is very cold, and lonely to live in. The Forests of Taiga The taiga is located near the top of the world, just below the tundra. The summers are warm, rainy, and humid while
winters are cold with only snowfall. In Arctic Canada, the gravelly rivers are floatable and you can float through the rolling tundra. It is the northernmost point on Earth's surface. No country owns the North Pole In the summer months, the sun is stuck above the North Pole’s horizon.
In the winter, the North Pole never sees the sun. In the summer months, the sun is stuck above the North Pole’s horizon.
In the winter, the North Pole never sees the sun. Tundra is located at the top of the world, near the North Pole and range from 60 N to 75 N latitude. They cover a tenth of the Earth. Abiotic Factors in the tundra are: coal, natural gas(es), zinc, rocks Moss grows at the bottom of the various lakes that can be found in the tundra. Some willow trees even grow sideways! Bearberry and Pasque flowers grow low to the ground. The North Pole If you hate the heat of the summer
then take a trip to the Tundra! Plants Recreational Activities Caribou have thick coats that allow it to be extra warm. the musk ox has thick and shaggy hair that covers their body to help it keep warm Animals Polar bears, Dall sheep, and wolves are also in the Tundra. There are many birds in the tundra, and these birds compete for food and space for nests. Robins and woodpeckers are especially challenged as they prefer high trees. Brown bears up in Alaska will eat the berries and squirrels in the area leaving less squirrels and then less for the birds to eat. The arctic fox is endangered due to parasites. Caribou are endangered from mosses freezing. Polar bears are endangered from the lack of seals due to the melting of the ice. Endangered Animals Without the tundra, the biodiversity of Earth would shrink by a large portion. In other words, there would be less different types of animals and plants. Animals such as the ptarmigan, polar bear, and caribou would either become severely endangered or die off completely. Plants such as the bearberry and the pasque flower would rarely be seen if seen at all around the world. Also, methane is locked up in the permafrost of the tundra. If the permafrost was gone, the methane would move to the atmosphere. Methane is a greenhouse gas in itself. The burning of methane takes oxygen out of the atmosphere and puts more carbon dioxide into it. The ice in the tundra is a large portion of the ice around the world. If this ice were to melt than there would be much more cold water that could freeze out many tropical species. The tundra is important in more ways than you can fathom.
