THE TUNDRA Location Tundra biomes are most commonly found in the Northern hemisphere. Tundra covers approximately 20% of the Earth, situated at latitudes 55° to 70° North. Tundra biomes appear in cold areas, and tundra are usually barren treeless places. Specific tundra areas are the Arctic, Antarctica, areas in Northern Canada, Greenland, and areas in Northern Russia. Climate Tundra is the coldest and driest biome in the world. In the winter 50˚ F and in the summer it rarely reaches over 50˚ F, just enough to thaw the surface. It hardly ever rains, and the rainfall can be about 10” every year. It is usually very cloudy, and so the tundra is not exposed to much sunlight. Some of the Caribou Scientific Name: Rangifer Tarandus Commonly Called: Caribou, Reindeer. Snowy Owl Ermine Scientific Name: Mustela Erminea Commonly Called: Short tailed weasel, Stout, Royskatt Ermines live in Northern Biomes, like taigas or tundras. They are well adapted to harsh conditions. Some of the Bearberries Arctic Moss Arctic Poppy Amazingly, the barren tundra land has produced amazing yellow flowers. This is an arctic poppy, and over the yeas of living in the tundra it has learned to adapt well. It can bloom for a short period of time in the summer. This moss does not need that much sunlight to survive. The Calliergon giganteum (arctic moss) is an underwater plant that lives in bogs and damp areas. It is a bryophyte, and has tiny rootlets instead of roots. The leaves are about one cell thick. Factors of Tundra Abiotic • Temperature: -50˚ F to 50˚ F • Rainfall • Mineral composition • Season • Altitude • Cloud coverage • Angle of sunlight • Wind (strong in the tundra) • Permafrost (only top layer of soil thaws in summer; so trees cannot grow) • Rocks Biotic • Plants like Arctic Mosses, bearberries, willows, etc. • Animals in the tundra include Arctic Foxes, polar bears, lemmings, ermines, snowy owls, caribous, voles. Resources • Some resources include mining. There is a lot of mining in the tundra, and substances like coal and gold are found. The tundra is very rich in mineral resources. • Oil drilling is very popular. The Tundra is full of oil, and oil drilling is done in the tundra a lot. How has Science Helped? Benefits Science has located where the oil and mining areas are, so as to find them quicker. Also, if they didn’t have science and just tried mining or drilling in random areas, a lot of the tundra would have been destroyed by now. Limitations Unfortunately, science still doesn’t know how to restore the tundra areas once they have destroyed it. Many of the tundras are getting ruined and polluted, and science doesn’t know how to solve this problem. Affect of Human Activity • Major human activities include oil drilling. When we drill for oil, we destroy the surrounding environment. Many plant life and animals are also killed, and habitats are ruined. This also effects the food chain. • When mining, acids and other forms of pollution are wasted, and that also pollutes the surrounding environment. It pollutes the air considerably, as well as the land. The noise drives animals away from their habitats, and population decrease. Interactions ENVIRONMENT As mentioned before, when mining and oil drilling, there is tons of pollution. Dusts and toxic gases are released that cause air pollution. These dusts also settle on neighboring lakes, ponds, (there aren’t many) and this makes in inhabitable for fish, plants, and other water creatures. It also produces loud noises, which drive animals away from their homes. They do not have a habitat, and some die. In addition, when one animal is killed, the whole food chain is affected. One of the greatest threats are oil spillage. This can damage tundra to a great extent. MONEY When the oil is drilled, and the minerals are mined, they are sold and a lot of money is made. In addition, while working for the oil/minerals, workers are needed. This causes for people to be employed, and get paid. In conclusion, by drilling oil and mining, a lot of money is made for a variety of people. SOCIAL (PEOPLE) The oil drilled is used in many various ways, for cooking, cars, and without it the world would be really different. Minerals mined are also used for medicine, and this helps people’s health. A lot of cures have been made.
