Temperate deciduous forest -Well-defined seasons with a distinct winter characterize this forest biome. Moderate climate and a growing season of 140-200 days during 4-6 frost-free months distinguish temperate forests. Temperature varies from -15° C to 25° C. Precipitation (750-1500 mm) is distributed evenly throughout the year. Temperate grassland- Semiarid, continental climates of the middle latitudes typically have between 25 cm and 50 cm of precipitation a year. Much of this falls as snow, serving as reservoir of moisture for the beginning of the growing season. Warm to hot summers are experienced, depending on latitude. In the winter, grassland temperatures can be as low as
1. 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
1. What is a biome? A biome is a large area of distinctive plants and animals, which are adapted to that environment. The climate and geography determines which type of biome can exist there. 2. Using the map describe the distribution of the biome (tropical rainforest/tropical deciduous forest). Tropical rainforest South America, Africa (Madagaskar), Asia. Tropical deciduous forest South America, Asia, Australia 3. Compare the climates (tropical rainforest/tropical deciduous forest). Tropical rainforest is wetter than tropical deciduous forest. Both of these biomes have a warm climate all year long. Tropical deciduous forest has a well defined dry and a wet season. During the dry season, the trees in tropical deciduous forest lose their leaves. 4. Using the climate diagram describe the climate of the region (tropical
Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus
Sonoran, Mojave and Great Basin. Others outside the U.S. include the Southern Asian realm, Neotropical (South and Central America), Ethiopian (Africa) and Australian. The major deserts of semiarid deserts include the sagebrush of Utah, Montana and Great Basin. They also include the Nearctic realm (North America, Newfoundland, Greenland, Russia, Europe and northern Asia). Coastal deserts occur in moderately cool to warm areas such as the Nearctic and Neotropical realm. A good example is the Atacama of Chile. Cold deserts occur in the Antarctic, Greenland and the Nearctic realm. Climate In hot and dry deserts temperatures exhibit daily extremes because the atmosphere contains little humidity to block the Sun's rays. Many mean annual temperatures range from 20-25° C. The extreme maximum ranges from 43.5-49° C. Minimum temperatures sometimes drop to -18° C. Rainfall is usually very low and/or
http://www.bbc.co.uk/nature/programmes/tv/jungle/vjungle.shtml Virtual Jungle worksheet I 1. Structure 1.1. Describe these layers Emergents The canopy trees are tall, but some species grow even taller until they stick right out above the canopy. These are called 'emergents' and can reach almost 90m in height. Up here they don't have to compete with other trees for light, but they are exposed to the high winds that lash the canopy during tropical storms. Emergents are the favourite nest sites of jungle eagles such as the harpy eagle of South America. Canopy Suspended 40m above the ground is the canopy - a belt of tree crowns supported by enormous rainforest tree trunks. This is the most productive and diverse habitat on Earth - perhaps 40% of the world's species spend their lives among its branches. The canopy's function is to photosynthesise
Different types of forests and their forms of usage TARTU 2010 Forest A forest (also called a wood, woodland, wold, weald, holt, frith) is an area with a high density of trees. Forests cover approximately 30% of land and 9.4% of all the planet earth. They are also responsible for regulating our planet's climate and act as large purifiers of airs, by absorbing carbon dioxide, and giving out oxygen. Different types of forests Forests are divided into following main types: o Tropical forest o Subtropical forest o Plantations o Boreal forest o Temperate forest o Seasonal or monsoon forest Tropical and Subtropical Forests Tropical and subtropical forests, also known as rainforests or tropical rainforests, are lavish and ample forests with broad leave tree. They are mostly found at lowlands near the equator - Asia, Africa, South & Central America and on many of the Pacific Islands
There are six large areas of temperate grassland: the Pampas in South America, the Veld in Africa, the Canterbury Plains in New Zealand, the Murray-Darling Basin in Australia, the Prairies in North America and the Steppes in Central Asia. 2. Colour the distribution of temperate grassland on the map. 3. How is temperate grassland called in these regions? Eurasia - steppe Hungary - puzda North America - prarie South America - pampa South Africa - veldt 4. What is forest steppe (forest steppe – metsastepp)? A forest steppe is a temperate-climate ecotone and habitat type composed of grassland interspersed with areas of woodland or forest. 5. Describe the climate of temperate grassland. Temperate grasslands have a temperate continental climate, which is cooler than savannas. Temperate grasslands have warm, humid summers with an average temperature of 18° C and cool, dry winters with an average temperature of 10° C. Most of the rain falls as
The population of Canada is about 31 million people. About 77% of the people live in cities which lie in a band about 100 miles wide above the border of the United States. The capital of Canada is Ottawa. Other large cities are Montreal, Toronto, Vancouver, Winnipeg and Quebec. Canada has two official languages English and French. It's interesting to know that about 61% of Canadians name English and 24% French their mother tongue. There are also many other languages spoken in Canada such as: Italian, Chinese, German, Polish, Ukrainian, Greek and Dutch. There are also many native languages such as Algonquian. The British and the French as the main settlers from Europe fought for hundreds of years before they managed to build up a country which was based on recognizing the cultural diversity of different nations in Canada. All the communities living in the country are encouraged to remember their origins and hold their own ethnic events and national festivals
Canada is a vast country, with a territory of 3.8 million square miles of land and fresh water it is the second biggest country in the world after Russia. Canada covers most of the northern part of North America. Canada has over 151,480 miles of coastline. Most of Canada's human population lives along its southern border. 3. Relief Canada's geography is very diverse. It has huge lakes, evergreen forests, prairies, meadows and beautiful mountains. There are thousands of miles of coastline with beaches, fjords and wild rivers flowing to the oceans. Canada is a country of wide open spaces and beautiful landscape where traveling visitors can unexpectedly bump into wild animals like bears or be struck by unusual sight like the scarecrows on the Cabot Trail. Canada is rich in natural
Its capital is Ottowa and other main cities are Toronto, Montreal and Vancouver. Almost 75 % of canadians lives within 300 kilometer of the USA border, because the climate is softer in the South. 89 % of Canada is almost unhabited. Its official languages are English and French, but many other languages are spoken too. Like Italian, Chinese, German, Polish, Ukrainian, Dutch and Creek. There are also many native languages such as Algonquian. Most of the canadian's speak English (67 %), but French is very largely spoken too (26 % of the canadians). Canada is based on recognizing the cultural diversity of different nations living in Canada. All the communities living on the country are encouraged to remember their origins and hold their own ethnic events and national festivals. Cultural diversity makes Canada even more interesting. There are many native peoples throughout Canadalike the Crees, Mohawks,

Each has its own provincial or territorial symbols. The major difference between a Canadian province and a territory is that a province receives relatively greater power and authority. The youngest of the territories and provinces is Nunavut, created from the east portion of The Northwest territories. 6. Towns, economy, agriculture The two largest cities in Canada are Montreal and Toronto, however, the capital is Ottawa. Canada's vast forests have made it the world's largest producer of pulpwood for making paper. The country also has enormous mineral reserves, especially of oil and iron, which have helped make Canada one of the ten leading industrial nations of the world. Canada is one of the few developed nations that is a net exporter of energy. Canada has vast deposits of natural gas on the east coast and large oil and gas resources centred in Alberta, and also present in neighbouring British Columbia and Saskatchewan
Savanna A savanna is a grassland ecosystem with scattered trees or shrubs. 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
In 1851 gold was discovered in eastern Australia. This brought along the great gold rush. Thousands of people went to the new land to find fortune. Forty years later the gold was found in the west. The miners of the east had a very hard time, the water was scarce and the roads were bad. But then the railway was built. Many of people who came to Australia to find gold stayed on to do other kinds of work. The found that Australia has other riches too, such as coal, copper, ironore, nickel, natural gas and more. The forests had good timber. Along seashorepearls and tortoise shells could be gathered. Some needed to manufacture such things as butter, cheese, shoes and clothing. Geographical position Australia is located in southern hemisphere. It's the only continent except for Antarctica that is all south of equator. Sometimes Australia is called the Island Continent. There is a great reason why. It really is an island. It is
Today Australia is a modern developed country with a diversified economy. Australia is an island continent of 7.7 million square kilometres, which makes it a little smaller than the USA. Located in south of Asia, between The Pacific and Indian Oceans, Australia is the World's driest continent. Although large areas of the centre are desert, Australia has a wide range of climate from tropical in the north to temperate in the south east, where it frequently snows in winter. Geographical position The coasts of Australia are surrounded by the Pacific Ocean, the Indian Ocean and the Southern Ocean. Four seas are surrounding Australia, which are the Timor Sea and Arafura Sea in the north of Australia, the Coral Sea in the north-east of Australia and the Tasman Sea, near the island of Tasmania, in the south-east of Australia. Government The full name of the county is the Commonwealth of Australia. Its territory is 7.7 million
The north part of the country gets about 300 mm of rain a year. Much of the rain soaks into the ground and does not form any rivers or lakes. Monsoon winds bring moist air during summer. This is the time of high rainfall. It’s known as “the wet “season. High temperature also means hat a lot of moisture evaporates or is used by plants. In the southern two thirds of the country the climate is temperate to cool. Winter temperatures can be low but not freezing. There are four seasons. The seasons are the opposite of our seasons. When we have summer then in Australia is winter. In Australia droughts and floods are pretty usual. The draught is caused by El Nino, a weather pattern which happens when the Southern Pacific Ocean heats up. This causes the wind direction to reverse. An El Nino occurs every four or five years, causing drought and bushfires. Droughts are followed by floods. Australia has three time zones
I'd like to present the main issues of our planet and today i'll name 5 of them. These are air pollution, water pollution, endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth
Natural Zones and Flora. There are five distinguishable natural zones in Australia. In the very east there are wet forests (1.) that occupy the space between the Great Dividing Range and the eastern coast. Westward from the Great Dividing Range the wet forests give place to beautiful grasslands with some trees . These grasslands are called the savannas (2.). Farther west the trees disappear and the bushlands (3.) begin. The real desert (4.) occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees (5.). Most of Australian trees are kinds of eucalyptus trees (or gum trees to Australians) and acacia ( wattle to Australians). Eucalyptus trees are found everywhere in Australia. There are many kinds of them and they greatly differ in size. One kind, the
an island but rather small for a continent. Australia is 1,800 miles from the mainland of Asia and almost half way round the world from Europe. More than 6,000 miles of ocean separate in from the America. Australia is the only continent except for Antarctica that lies all south of the equator. The natural zones of Australia are very various. There are deserts, semi deserts, grasslands, savannas, bushlands and rainforests. The wet forests occupy the narrow region in the east. Most of the animals, birds and insects live in that region, because there is enough food. The savannas which are grasslands with some trees are mostly in the west. Farther west are the bushlands. The real deserts occupy the centre of the Western Plateau. In the very south west there are thin forests of evergreens trees. Australia is the driest inhabited continent, the flattest, and has the oldest and least fertile soils.
Report Compiler: Teisi Timma 8a Teacher: Esther Linask Tartu 2009 Acid Rain Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because precipitation can eventually wash pollutants into streams, lakes, and rivers.
Australia's name means "southland."It is south of the equator. Sometimes it is also called the island continent because it is an island. There are about twenty million people in Australia.It is 1,800 miles from the mainland of Asia and almost half way round the world from Europe. More than 600 miles of ocean separate it from Americas. Since Australia is south of the equator, its seasons are just the opposite of ours. It has summer while we have winter, and the other way round. States and Territories. Australia consists of six states, two territories and eight external territories. The six states are: Western Australia (capital Perth), South Australia (capital Adelaide), Queenslnd (capital Brisbane), New South Wales (capital Sydney), Victoria (capital Melbourne) and Tasmania (capital Hobert). The two territories are the Northern territory (capital Darwin) and the Capital territory (capital Canberra). Politics
fog. SO2 and NOx come mainly from power stations and factories burning fossil fuels, or from motor vehicles. · Carbon dioxide in the air can dissolve in rain water to form carbonic acid, H 2CO3 CO2 + H2O H2CO3 · During the last century the rain water in some parts of the world has become far more acidic. This acid rain has been caused by the emission of pollutants gasses such as sulfuric dioxide, when goal is burned in electric power stations, sulfur impurities form sulfur dioxide S + O2 SO2 · The gas is also produced when fuels obtained crude oil are burned. When sulfur dioxide is released into the air it reacts with water and oxygen to form sulfuric acid, which is strong it ionizes completely to hydrogen ions.

The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)). The stem(tüvi) of the flower can grow up to 3 metres tall, with the flower head reaching 30 cm in diameter. The term "sunflower" is also used to refer(nimetama, viitama, üle andma) to all plants of the genus(perekond, sugu) Helianthus, many of which are perennial(alaline, aastaringne) plants. What is usually called the flower is actually a head (formally(ametlikult) composite(liit-, komposiit- ; korvõieline, komposiit) flower) of numerous flowers (florets) crowded(täistuubitud, tunglev, rahvarohke) together
East Anglia are perfectly flat. In Ireland all the highland areas are situated on the coastal areas but there are no peaks over 1100 m. Great Britain is rich in rivers but they are rather short. The longest rivers are the Severn, which flows into the Bristol Channel and the Thames which flows just through the city of London. Both of them are an important part of the inland transport network for transporting such products as coal, iron ore and steel. The largest lake in Great Britain, Loch Lomond, lies in Scotland. There are many lakes in Scotland. They are narrow and long in shape because of the mountains. Loch Ness is well-known for its mysterious monster. 6 Climate Britain has a maritime temperate climate which means that it's quite mild, with
The Prime Minister is really the head of government in Canada. Stephen Harper is currently the PM. National symbols. The use of the maple leaf as a Canadian symbol dates back to the early 18th century, and is on its current and previous flags, the penny, and on the coat of arms. The national colours are red and white which also appear on the flag. The national animal is the beaver and it is because the fur trade. Maple syrup is very important for Canadians also. Hockey is the official winter sport. Canada's official colours are red and white. The colours appear on the flag. History. Almost a thousand years ago men from Norway sailed across the Atlantic Ocean and "discovered" America about 4 centuries before Columbus. In 985 AD Vikings who wanted to go to Greenland from Iceland were blown off their course and they reached Canada. It is thought that they reached Labrador. They saw forested areas there and further exploration were encouraged by this discovery because the
Researchers have confirmed that a wild tiger, photographed by a farmer in the Qinba Mountains of Shaanxi Province, Central China, is indeed that of the critically endangered South China tiger. The South China tiger classified as one of only five subspecies of tiger still alive today is extremely rare, with only an estimated 20 to 30 still remaining in the wild. The wildlife and conservation group WWF says the South China tiger is actually native to the Hainan most forests of south-east China, and because there are so few individuals left, it is regarded by many scientists as being "functionally extinct" in the wild. But a group called Save China's Tigers has been working on a captive- breeding programme and hopes to reach an agreement with China's State Forestry Administration to reintroduce captive-bred animals into the wild. If all goes well, the first individuals could be reintroduced to coincide with the Beijing Olympic Games in 2008.
The population increases very slowly and somewhere between the `70s and `80s actually fell. Although there are more male births than female, the male mortality rate is rather high. 6. Climate Britain generally has mild climate. The weather tends to be very changeable as a result of the influences of different air masses. The currents bring warm air in from across the Atlantic. There are few extremes. Southern Britain is warmer than Northern because of its latitude, but in winter the North Atlantic Drift keeps the west milder than the east. Wales and the southern peninsula have the most moderate climate and Eastern England the most extreme. Annual rainfall is fairly evenly distributed but the amount of precipitation varies greatly between the mountainous areas of the west and the central and eastern parts. 7. Animals, plants Animals The diversity of animals is modest because of several factors: the size of
The unofficial anthem of Australia is `Waltzing Matilda'. It tells a story about a swagman, who has named his sleeping blanket Matilda. He is chased by police for stealing a sheep which he wanted to eat. The swagman doesn't want to be punished, so he jumps into a billabong and drowns. The golden wattle was proclaimed the official national floral emblem in 1988. It is a spreading shrub or a small tree, which grows in the under storey of open forest, woodland and open scrub in South Australia, Victoria, New South Wales and the Australian Capital Territory. Green and gold were proclaimed Australia's national colour by the Governor-General in 1984. Before the proclamation, Australia had no official colour, although three colour combinations traditionally had a claim to be Australia's national colours: red, white and blue; blue and gold; and green and gold.

provinces, the Appalachians, St. Lawrence and Great Lakes lowlands, Canadian Shield, The Prairies, mountain ranges and high plateaus of the Canadian Cordillera, and northern Canada. Climate Canada's climate varies wildly based on geography, from perma-frost in the north to four distinct seasons towards the equator. In this region the temperature can climb up to 35 degrees Celsius in the summer and descend to a chilly -25 degrees Celsius during winter. Canada's climate and environment are one of the main reasons that Canada is such a succesful country. The blend of natural resources and climate sustains us. The seasons dictate the look of the land: according to whether the natural environment is in a state of dormancy or growth. Canada's climate is characterized by its diversity, as temperature and precipitation differ depending on where you are and what time of year it is. Other than the North where it's above

We use a lot of energy - in our homes, in businesses, inindustry, and for traveling between all these different places. The industrial sector uses almost one-third of the total energy. The residential and commercial sectors combined use 39 percent of all energy. These two sectors include all 4 types of buildings, such as houses, offices, stores, restaurants, and places of worship. Energy used for transportation accounts for more than a quarter of all energy. Picture 2.1. Share of energy consumed by major selectors of the economy (2007) 2.1 Uses of energy in homes The ability to maintain desired temperatures is one of the most important accomplishments of modern technology. Our ovens, freezers, and homes can be kept at any temperature we choose, a luxury that wasn't possible 100 years ago

The soil microflora largely depends on the type of soil, temperature, moisture, plant growth, nutrients, pH, and many other factors which may vary between locations but also within a single plot and over very small distances (OECD, 2007). Nevertheless of the quantity of microflora, biomass of all microorganisms living in soil play an important role in the functioning of entire soil ecosystems because their enormous biochemical activity (Barabasz et al. 2002). Soil microflora cycles carbon, nitrogen, phosphorus, and sulfur, plays a role in soil structure
