All studied biomes

Key features for all studied biomes . Tundra The main seasons are winter and summer. The tundra is the world's coldest and driest biomes. The average annual temperature is -28° C. Nights can last for weeks when the sun barely rises during some months in the winter, and the temperature can drop to -70° C. During the summer the sun shines almost 24 hours a day. Summer are usually warm. Average summer temperatures range from 3° to 16°C. TaigaTaiga is the Russian word for forest and is the largest biome in the world. It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. Some of the animals in the taiga hibernate in the winter, some fly south if they can, while some just cooperate with the environment. GrasslandsGrassland biomes can be found in the middle latitudes. They can...

Canada

Some of the biggest and widespread are bears. Cougars are the largest cats in Canada. Wolves can be heard but not as easily seen as their cousin the coyote. Bison are now exclusively farmed but goats and sheep can still be seen in the wild. Moose, deer and caribou are also widespread as are the otter and beaver. Reptiles, amphibians and a large selection of snakes also call Canada home. Squirrels, chipmunks, racoons and skunks often found in and around cities. Some of the most common animals to spot in Canada are birds, including Canada Geese, Bald Eagles and the Great Blue Heron. Canada's varied climates allow for a large selection of spiders, bugs and insect while the countless rivers, lakes and 3 oceans are home to dolphins, whales, salmon, sharks and many other species of fish and sealife. There are five major Biomes in Canada: Arctic Biomes, Tundras, Taigas, Praeries and Deciduous Forests. The Tundra is located near the Arctic region. It is permafrost and desert-like. The area is very cold and windy. The growing season is 50-60 days. Some of the plants that can survive there are lichens and mosses. Typical animals for the Tundra are musk oxen, elks, moose, lemmings, wolves and foxes. The Taiga biome, also known as coniferous forests is located south of the Tundra region. Taigas are the largest biomes on Earth and they are a major source of oxygen. The Climate there is cold and harsh. Precipitation is low. The growing season is short. Only deciduous trees can grow there since the soil is acidic. Some typical animals are brown bears, foxes, geese, lynxes and moose. Prairies are temperate grassland. They consist of plains of grass that are hot in the summer and cold in the winter. Prairies are made by fires. The soil is rich and the precipi...

Kanada referaat

Parts of Canada are very mountainous.The highest mountain is the Yukon's Mount Logan, which is 6050 meters high. Canada has many mountain ranges, including the Appalachians, Torngats, Laurentians, the Rockies, Coastal and Mackenzie ranges and the Pelly Mountains. Canada is rich in natural wonders, but the Niagara Falls (which is the second largest waterfall in the world) are one of the greatest attractions in the world. About twelve million tourists come to see the beauty of the falling waters every year. The Horseshoe Falls are much bigger and have more strength that the American Falls. People can enjoy the noise and the sight of the waters from the boats which take them right next to the falls. In the evenings, when the falls are illuminated by colorful spotlights, they are magnificent. There are five major biomes in Canada: Arctic Biomes, Tundras, Taigas, Prairies and Decidious Forests. The Arctic Biome is very cold and windy. There are long periods of darkness and the growing season is very short so there are almost no plants. Some of the typical animals are the Arctic fox, ermines, polar bears, Arctic terns, walruses and seals. The Tundra is located near the Arctic region. It's permafrost and desertlike. Some of the plants that can survive are lichens and mosses. Typical animals are musk oxen, elks, moose, lemmings, wolves and foxes. The taiga biome, also known as coniferous forests is located south of the Tundra region. They are major source of oxygen. The climate is cold and harsh. The soil is acidic so only deciduous trees can grow there: like hemlocks, pines, larches, spruces and firs. Typical animals are brown bears, foxes, geese, lynxes and moose. Prairies are temperate grasslands. The consist of plains of grass that a...

Savanna

In savannas trees are small or widely spaced so that the canopy does not close. It is often believed that savannas are characterized by widely spaced, scattered trees, however in many savanna communities tree densities are higher and trees are more regularly spaced than in forest communities. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of C4 grasses. Savannas are also characterised by seasonal water availability, with the majority of rainfall being confined to one season of the year. Savannas can be associated with several types of biomes . Savannas are frequently seen as a transitional zone, occurring between forest and desert or prairie. Although the term savanna is believed to have originally come from a Native American word describing "land which is without trees but with much grass either tall or short", by the late 1800s it was used to mean "land with both grass and trees". It now refers to land with grass and either scattered trees or an open canopy of trees. Changes in fire management Savannas are subject to regular fires and the ecosystem appears to be the result of human use of fire. For example Native Americans created subtropical savannas by periodic burning in some areas of the US southeastern coast where...

Canada has about two million lakes and they cover about 7.6% of Canada's land. The biggest lakes in order by their surface are Lake Huron, Lake Great Bear, Lake Superior, Lake Great Slave (which is also the deepest), Lake Winnipeg, Lake Erie and Lake Ontario. There are also a lot of rivers in Canada. The longest river is the Mackenzie River which is 4241 kilometers long. It runs through the Northwest Territories. Other large and important rivers are the St. Lawrence River, the Yukon River, the Columbia River, the Nelson River, the Churchill River and the Fraser River. Nature. Canada's land ranges from fertile agricultural plains in the south to freezing tundra in the north. The southwest of Canada has a mild climate. Cold winters characterize most of the rest of Canada. The magnetic North Pole is within Nunavut. There are five biomes in Canada: the Arctic Biome, the Tundra, the Taiga Biome, the Prairies and the Deciduous Forests. The Arctic biome is cold, windy and the land is permafrost. There are long periods of darkness and light. The growing season is very short. Some typical animals are Arctic foxes, ermines, polar bears, Arctic terns, walruses and seals. The Tundra is located near the Arctic region. It is cold and windy as well. The land is permafrost and desert-like. The growing season is 50-60 days and that's why there are plants like mosses and lichens.

Temperate deciduous forests, woodlands and shrub

Temperate deciduous forests, woodlands and shrub Tartu 2008 Location: Temperate forests are typical of all European continent, the Eastern region of Asia (in special, Chinese and Japan) and North America. Also are finded in tempered areas of South America. Climate: The average temperature in temperate forests is 50° F. Summers are mild, and average about 70° F, while winter temperatures are often well blow freezing. The average yearly precipitation is 30-60 inches. This precipitation falls throughout the year, but in the winter it falls as snow. There are four seasons in this biome, with warm summers and cold winters, often snowy. In autumn, the leaves change color and fall from the trees. The leaves decay on the forest floor, so the soil is very rich. Because of this, and because of the long growing season, many deciduous forests have been cut down for farming purposes. Plants: Trees of this biome include hardwood...

Kanada

Rivers in Canada flow into five major ocean drainage basins: the Pacific, Arctic and Atlantic oceans and Hudson Bay. The St. Lawrence is Canada's most important river, providing a seaway for ships from the Great Lakes to the Atlantic Ocean. The longest Canadian river is the Mackenzie, which flows 4 241 kilometres through the Northwest Territories. Canada is quite mountainous. The highest point is Mount Logan with 5.959 m. It is the second-highest peak in North America. Mt. Logan is located within Kluane National Park and Reserve in southwestern Yukon. The Rocky Mountains, often called the Rockies, are a broad mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles (4,800 kilometres) from British Columbia, in Canada, to New Mexico, in the United States. Mount Robson, at 12,972 feet (3,954 meters) is the highest peak in the Canadian Rockies Canada has many different biomes . For instance: The Arctic. It is a very cold, windy, and often snowy biome located around the North Pole. Long periods of darkness (in the winter) and light (in the summer) also affect Arctic life. Nature. Canada is one of the most exciting countries in the world. It has many interesting cities, like Toronto, North Vancouver, Montreal or Halifax. But also some of the most impressive nature, which is great for outdoor activities, like hiking, skiing, rafting and fishing. It is because of the different biomes that appear in that country. One can do everything one wants to do in different parts of the land. The animal life is also diverse in Canada. There are many interesting animals. Badger is one of them. It belongs to the weasel family. It is one of the biggest in that carnivore family. Good paintbrushes are made from its fur. They eat snakes, squirrels and insects. Snake poison doesn't harm these mammals unless the...

Australia.

People are clustered in the regions of the south and east. The climates in these parts of Australia are well suited for ranching and farming. The distribution of climates in Australia is determined by the location of the continent. The tropical climates are found in Northern Australia. Warm ocean winds near the equator bring heavy rain to there areas, especially in summer, so that tropical rainforests grow there. The coastal areas, where the majority of Australians lives, have the most dependable rainfall in Australia. Westerlies bring winter rains to parts of Australia's southern coast. Australia's east coast gets rain all year round. Between the tropical north and middle latitude south, lie Australia's dry core-deserts. Deserts in that area receive almost no rainfall. In most areas of Australia rainfall is low and unpredictable. In conclusion, Australia has three biomes : tropical, savannas and desert. States and territories: The Commonwealth of Australia is made up of 8 states and territories: Western Australia, Southern Australia, New South Wales, Queensland, Victoria, Northern Territory, the Australian Capital Territory and Tasmania. The biggest of them is Western Australia, which is almost one third of the whole Australia. The biggest towns are all in the eastern part of Australia. Sydney, with the population of 4,3 million people and Melbourne, with 3,9 million people. The capital of Australia is Canberra, although it's not as populated, but only about 340 000 people living there. Outback refers to remote arid areas of Australia. There are not very many people living there, and those who do, are Aborigines. Industry, minerals and power: Agriculture is the major industry in Australia. People grow grain and bred sheep.

Geograafia KT-8.klass

Most temperate grasslands are inhabited by hares, mice, and other small rodents. These animals have sharp teeth that are able to easily gnaw through grass. Some of the familiar rodents found in the North American grasslands are prairie dogs, mice, rats, and ground squirrels. Prairie dogs are cute, burrowing rodents that live in underground communities. A dominant male heads a prairie dog family. They make their home in underground burrows that consist of several chambers and entrances. Taiga - Most animals migrate to warmer climates once the cold weather begins. Some animals have adapted to life in the taiga by hibernating when temperatures drop. Other animals have adapted to the extreme cold temperatures by producing a layer of insulating feathers or fur to protect them from the cold. 13. Which human activities endanger the biome? Temperate forest: one of the most altered biomes on the planet. By looking at a map you will see that our population density very closely corresponds to the distribution of Temperate Forests. We use the wood of these trees for construction, firewood and art. They have been cleared for farming and to build communities. These human activities have led to the decline and loss of these forests in many parts of the world. Temperate rainforest: Farming, mining, hunting, logging and urbanization are some of the human activities that have affected negatively this biome, resulting in biodiversity loss, pollution, deforestation and habitat loss and fragmentation. Temperate grassland: Grasslands in temperate latitudes have been modified by human activity to such a degree that little remains today in a natural state - and substantially less in some form of long-term protection. Only 5.5% of the world's temperate grasslands are currently protected within the global system of protected areas....

Bioomid

makroökosüsteem on klimaatiliselt ja geograafiliselt defineeritud, kui sarnaste tingimustega piiritletav planeedi ala, mida saab liigitada seal kasvavate taimede ja seal elavate loomade ning pinnaseorganismide järgi. Temperatuur, pinnas, valguse ja vee kogus määravad kindlaks, mis taime- ja looma liigid bioomis elavad. Kõrbed katavad umbes 20-33 % Maa pinnast. Kõrbe pinnasele on iseloomulik suurem aurustumine kui sademete hulk. Kuna enamikes kõrbetes ei ole sademeid palju ei sisalda pinnas pinnavett, muldadel on suhteliselt madalad soolakontsentratsioonid, mis on ainult vastavate tingimustega kohanenud kõrbetaimede kasvu jaoks väga soodne omadus. Sõltuvalt kõrbest, ulatuvad mullatüübid peene tekstuuriga liivast kuni kruusa ja lahtise kivimini. Kuivad kõrbed on tavaliselt madalatel laiuskraadidel ja neid võib leida Põhja- Ameerikas, Lõuna-Ameerikas, Aa...
