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.

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
Oceans. 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

Introduction If you had to use two words to describe Canada, they might be large and diverse. Canada is the second largest country in the world, bordered by three oceans, and across the country, Canadians experience many different landscapes from rolling plains and mountains to the cold tundra of the north. Despite Canada's great size, it is
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 wonders, one of them, the Niagara Falls between lakes Erie and Ontario, which is the
Canada's area is about 10 million square kilometers and its population is 31 000 000. 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.
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 concentrated in short bursts between long rainless periods. In semiarid deserts summer temperatures usually average between 21-27° C. It normally does not go above 38° C and evening temperatures are cool, at around 10° C. The average rainfall ranges from 2-4 cm annually. In coastal deserts the average summer temperature ranges from 13-24° C; winter temperatures are 5° C or below. The maximum annual temperature is about 35° C and the minimum is about -4° C. In Chile, the temperature ranges from -2 to 5° C in July and 21-25° C in January. The average rainfall measures 8-13 cm in many areas. The maximum annual precipitation over a long period of years has been 37 cm with a minimum of 5 cm. In cold deserts the mean winter temperature is between -2 to 4° C and the mean summer temperature is between 21-26° C
Inuit Culture, Traditions, and History Traditional Inuit way of life was influenced by the harsh climate and stark landscapes of the Arctic tundra from beliefs inspired by stories of the aurora to practicalities like homes made of snow. Inuit invented tools, gear, and methods to help them survive in this environment. Read on to learn more about traditional Inuit ways of life, and how Inuit culture has been changed over the past century. Geography Inuit communities are found in the Arctic, in the Northwest Territories, Labrador and Quebec in Canada, above tree line in Alaska (where people are called the Inupiat and Yupik), and in Russia
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
Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, so it is slightly acidic. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern
Estonian University of Life Sciences Report on Soil Microflora By Katrin Vares Tartu 2013 Introduction The purpose of this report is to define soil microflora and establish the importance of it. Since the microorganisms clearly play an important role in preserving the balance of life, the next objective is to look into factors that influence this balance. Natural conditions and cultural impact could be considered as the variables that correlate the most with the activity and composition of microflora, hence some of the natural and cultural factors will be looked into a little more in detail.

belonged to the Vikings lacked lumber. In AD 1000 Leif Ericson became the first European to land in North America. The first colony was established what was described as Vinland by the Vikings. It was located on the northernmost tip of todays Newfoundland. There has also been a theory that the Vikings penetrated Hudson Bay and reached the Great Lakes region but recent investigations have cast serious doubt on it. The Greenland colony died out during the 15th century and the Viking adventures in Canada must have come to an end long before that time. The Colony of New France By 1600 French interest in Canada was renewed because of the beaver pelt trade and the fishing industry. First French colony was established in eastern Canada. Because of the French settlement the French established a claim to the Gulf of St. Lawrence area. An agreement was made between the King of France and a
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

Canada 8a Teacher: Merike Sisask Composer: Kärt Kalvet 2010 Canada, Kärt Kalvet 8a Canada General Information Canada is in North America. It's area is 9220970 sq km. Canada's population is 313.612.000 people. Canada is divided into 10 provinces and 3 territories. The capital of Canada is Ottawa. Canada has constitutional monarchy. The head of state in Canada's government is the Queen of England. There are two main languages in Canada: English and French. Canada's curreny is Canadian dollar (1 dollar=100 cents[Can$]). The highest peak of Canada is Mount Logan, 5959 metres. The lowest point is sea level. The longest river is the Mackenzie. The climate and geography of Canada vary greatly from temperate in the south to arctic in the north and from islands and plains in the east to mountains in the west. Location Canada is located in the northern-most region of North America
Farther inland, fields of wheat and other grains cover Canada's vast prairies. Thes fertile farmlands contrast vividly with the Arctic wastelands to the north. Most of the largest towns and industrial areas lie near the Great Lakes and the St Lawrence River in central Canada. In the east, fishing villages and sandy beaches dot the Atlantic coast. Across the country, Canadians experience many different landscapes from rolling plains and mountains to the cold tundra of the north. Geographically, Canada can be divided into five major regions : the Pacific Region, the Prairie Provinces, Central Canada, the Atlantic Provinces, and the North. The Pacific Region includes Canada's westernmost province, British Columbia. The region is known for its mild coastal climate, its forests, and its spectacular mountains, including the famous Rockies. The Rocky Mountains are the youngest and highest mountains in Canada.

is a great challenge because I have not done anything like this before, especially in English. Primary goal for me is to improve my knowledge about renewable energy and also usage of English language. This report is going to talk about biogas. It provides a brief review of usage and future prospects of the biogas. I have tried to make this report as understandable as possible. By the end of this report I want to come to a conclusion whether biogas is the best source of future energy or are there any other sources that are better. What is biogas? Typically it refers to the gas produced by the anaerobic digestion or fermentation of organic matter including manure, sewage sludge, municipal solid waste, biodegradable waste. If opportunely refined it can be used for electricity production. Also for space-, water- or process heating. Unintentional production of biogases has been an ongoing issue in many regions of

These North American reindeer became known as caribou. Although they are called by different names, they are both considered to be a single species. Unlike deer, both the male and female have antlers. The antlers of the male are long, branched and massive, and they are a little flattened at the ends. The antlers of the female are much shorter, simpler and more slender and irregular. Their large, spreading hooves support the animal in snow in the winter and marshy tundra in the summer. Reindeer are also great swimmers and use their feet as paddles. They can also lower their metabolic rate and go into a semi-hibernation when conditions get very harsh. When it looks like there is nothing to eat on the winter tundra, reindeer will scrape the snow away with their wide feet or antlers and eat lichens, dried sedges and small shrubs. In the summer they the will eat leaves of willows, sedges, flowering plants, mushrooms.
ICE AGE The earth is very old. During its long history there have been many changes in climate. Between one and two million years ago one of these changes took place the great Ice Age began. It grew colder in the Far North. More snow fell in the winter than could melt away in the summer. The snow grew deeper and deeper. It changed to solid ice. As more snow fell, the ice grew thicker. It began to move. Great sheets of moving ice, or glaciers, were formed. The edges of the sheets were pushed outward. At last the ice covered most of what is now Canada. And it spread southward into what is now the United States. The ice was probably a mile deep in places. It moved over hills and valleys, rivers and forests

generator. In this case the energy extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. *Pumped storage hydroelectricity produces electricity to supply high peak demands by moving water between reservoirs at different elevations. At times of low electrical demand, excess generation capacity is used to pump water into the reservoir. And when there is a big demand, like in the evenings, then the water is released and flows through the turbines. there are many Advantages for hydropower. *The mayor advantage of hydroelectricity is eliminating the cost of fuel. You don't have to fear about the increasing cost of fossil fuels like oil and natural gas. *The second advantage is that hydroelectric plants last longer than fuel-fired plants. Some hydro plants have been operational about 100 years.

Formaldehyde Formaldehyde is a colorless, flammable gas at room temperature. It has a pungent, distinct odor and may cause a burning sensation to the eyes, nose, and lungs at high concentrations. Formaldehyde is also known as methanal, methylene oxide, oxymethylene, methylaldehyde, and oxomethane. Formaldehyde can react with many other chemicals, and it will break down into methanol (wood alcohol) and carbon monoxide at very high temperatures. Formaldehyde is naturally produced in very small amounts in our bodies as a part of our normal, everyday metabolism and causes us no harm. It can also be found in the air that we breathe at home and at work, in the food we eat, and in some products that we put on our skin. A major source of formaldehyde that we breathe every day is found in smog in the lower atmosphere. Automobile
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. The outer flowers are the ray florets(pähik (õisiku osa) and can be yellow, maroon, orange, or other colors, and are sterile(steriilne, viljatu). The florets inside the circular head are called disc florets.
The coat of arms features a kangaroo and an emu (the national animals of Australia), golden wattle (the national floral emblem), a shield with the coats of arms of the six states of Australia and a star for all states and territories. Australia's national anthem is "Advance Australia Fair", which replaced "God Save The Queen" in 1984. the unofficial anthem is "Waltzing Matilda". As said before Australias national animals are kangaroos and emus. Often coalas are mentioned too, its floral emblem is the golden wattle and its national colours are the colours of its flag red, white and blue. Head of state Head of state is Queen Elizabeth II, who is queen of United Kingdom and also queen is Australia. In practice, Governor General performs her functions in queen's absence. Since 1989 Bill Hayden has been the Governor General Government
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may rise a predicted from 2 to 6 degrees Celsius

Normal rain water is slightly acidic and has a pH range of 5.3-6.0. Acid deposition is anything below that scale. It is also important to note that the pH scale is logarithmic and each whole number on the scale represents a 10-fold change. Causes and History of Acid Rain Acid deposition can occur via natural sources like volcanoes and rotting vegetation but it is mainly caused by the release of sulfur dioxide and nitrogen oxide during fossil fuel combustion. When these gases are discharged into the atmosphere they react with the water, oxygen, and other gases already present there to form sulfuric acid, ammonium nitrate, and nitric acid. These acids then disperse over large areas because of wind patterns and fall back to the ground as acid rain or other forms of precipitation. The gases responsible for acid deposition are normally a byproduct of electric power generation and the burning of coal
