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
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 -40° C, and in the summer it can be as high 20° C. There are two real seasons: a growing season and a dormant season. The growing season is when there is no frost and plants can grow (which lasts from 100 to 175 days). During the dormant (not growing) season nothing can grow because it's too cold. Taiga- Long, cold winters, and short, mild, wet summers are typical of this region. In the winter, chilly winds from the arctic cause bitterly cold weather in the taiga. The length of day also varies with the seasons in the taiga. Winter days are short, while summer days are long. The average temperature is below freezing for six months out of the year
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
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 hardwoods such as maple, oak, hickory, and beech. There are often some evergreens, such as hemlock, spruce, and fir growing amongst them. Decidous forests have usually 3-5 layers of plants; Top layer, or canopy: tall deciduous trees.
The Coral Sea is the warmest that is why many corals live in the seas. The skeletons of these tiny organisms have formed a great belt of coral- called the Great Barrier Reef. Its is 2000 km long and 2-150 km wide. There are five distinguishable natural zones in Australia. In the very east there are wet forests that occupy the space between the Great Dividing Range and the eastern coast. The wet forests give place to beautiful grasslands with some trees called the savannas. Farther west the trees disappear and the bushlands begin. The real desert occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees. Most of Australian trees are kinds of eucalyptus (or gum tree to Australians) and acacia (wattle of Australians). Eucalyptuses give the people timber and eucalyptus oil. Of 600 kinds of acacias the golden wattle, the national flower of Australia, is the best known.
If you were asked to show on a world map the regions with the most biodiversity, your finger would probably end up pointing at the Amazon, the Congo Basin or the island of Borneo. But I chose New Guinea, an island that represents no more than 1% of the world's landmass, an array of extraordinary animals and plants have also flourished, such as tree kangaroos and birds of paradise. Close to 10% of the world's vertebrates are concentrated here, while 7% of the world's higher (vascular) plants grow on the island's productive soils. 3 Geography Papua New Guinea consists of over 600 islands and lies in the middle of the long chain of islands stretching from mainland South-East Asia. The mainland and larger islands are mountainous and rugged, divided by large fertile upland valleys. Fast- flowing rivers from the highlands descend to the coastal plains. A line of active
democracy. The Parliament consists of two houses: the 76-member Senate and the 148- member House of Representatives. The Prime Minister is elected by the House of Representatives and the Cabinet. The current Prime Minister is Kevin Rudd. History, discovery: Though nobody had seen it, people thought long before the seventeenth century, that there was a land in the southern ocean. It was called the Unknown South Land. But more than 60 000 years before the arrival of the European settlers, Aboriginal people inhabited most areas of the nowadays Australian European settlement. There were estimated 300,000 Indigenous Australians living on the continent. The Dutch navigator Janszoon was the first to find the South Land. He sighted the coast in 1606. Then Abel Tasman visited an island off the southern coast of Australia in 1642 and the island was named Tasmania after him. In 1770 British sailor James Cook came to
The Executive power in Australia is in the hands of the Commonwealth Government lead by the Prime Minister. Today the Prime Minister is John Howard, the leader of the Liberal Party. History Australia was once a part of the giant continent Gondwana. It included Africa, South America and Antarctica. First Australia and Antarctica split from Gondwana, then Australia broke away from Antarctica and began to move north. Aborigines arrived there about 50 000 years ago. They had occupied the whole continent by 30 000 years ago. At that time Tasmania was still part of the mainland. About 20 000 years ago the ice began to melt and the rising water level cut Tasmania off from the mainland. Traders from what is now Indonesia are thought to have been visiting Australia well before the 17th century. Chinese, Malaysian and Arab sea Captains may also have landed in Northern Australia after the 15 th century.
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.
learn using special programs on the TV and radio. People living in big cities do not all use cars for moving. Getting to work with a bicycle or with even a sailing boat is not strange in Australia. Aborigines are described in the History topic History Aborigines Anthropologists say that the Aborigines were the first humans in the world. Even the word "aboriginal" means "the first" or "earliest known". It is confirmed that people lived in Australia about 40000 years ago. At that time, which is called the last great Ice Age, Australia was joined with New Guinea. Because sea passages were narrower between the Java and Borneo islands, the first Aborigines could reach Australia from the north. When they finally got to Australia, it was in a much better condition than nowadays. There were large animals, who are now extinct, that provided much meat. The Aborigines lived in harmony with the environment. Because they
Norway in the east and France in the south. Britain also has many dependant territories which are scattered throughout the world and are the remains of the huge former British Empire. Today Britain assists them, but they may become independent whenever they wish. There have been some difficulties with some of the territories. Argentina has made claims to the Falkland Islands and Spain to Gibraltar. History When the glaciers retreated from Britain about 10,000 years ago, Stone-Age men started to inhabit the isles. The early Britons came across the land bridge which joined Britain to the continent. They were cave-dwellers at first. This way of life was replaced by the invaders from the Mediterranean lands. These men were the first farmers. In about 500 BC came the people whose homeland was near the Rhine River. These were the Celts. The Roman invasion began in 43AD. The Romans were highly organized conquerors. They built good roads, baths and bridges
about ancient Australia. The east is the mountainous part of the country. There is The Great Dividing Range. It runs along the Pacific coast and finds it end in Tasmania. The mountains are old and worn down. The highest mountains on the Australian mainland are in an area known as the Australian Alps. They are a small part of the Great Dividing Range. The Highest Peak on the mainland is 2228m high – Mt Kosciusko. One of the largest monoliths – Ayers Rock, also known as Uluru, can also be found in Australia. It’s located in the middle of the country. The monolith is 348 m high. The flat hot centre of Australia is called the outback. The Outback is more then two thirds of Australia, but less than 100 000 people live there. Between the Western Australian Shield and the Great Dividing Range is the Great Artesian Basin region. It is an area of vast plains. It includes three major basins: The Carpentaria, the Eyre and the Murray basins
power or the country is put to life by the Parliament. Parliament consists of The House of Representatives (esindajate koda) and the Senat. The House of representatives consists of 150 members. The Senat comprises 12 representatives from each state and 2 from each territory. The executive power in Australia is in the hands of the Prime Minister. Today the Prime Minister is John Howard. History. The first inhabitants in Australia are the Aborigines who came there about 60000 years ago. The first known Europeans to arrive in Australia were the Dutch. William Jaanzsoon tried to reach the East Indies, but landed in western Australia in 1611. The Dutch gave a poor account of Australia considering it to be and arid land inhabited by fierce savages. Abel Tasman was also a Dutch sailor and he discovered Tasmania. Captain James Cook discovered the fertile eastern coast in 1770 and had a more favourable outlook. He explored the coast and named some most important
The nearest neighbor may be a hundred kilometers away. The nearest city may be more than one thousand kilometers away. Many people in this area live on sheep stations which are enormous farms. Uluru One of the most beautiful things in Australia is Uluru (Ayers Rock) in the outback. It is an enormous rock alone in the middle of the desert. It is three kilometers long and 348 metres high. There is another 2000 meters under the ground. Uluru is 600 000 000 years old and it is the largest rock in the world. The Great Barrier Reef. One of the natural wonders of the modern world is the Great Barrier Reef. It is located off the northeast coast of Australia. It is the biggest coral reef in the world extending 2000 kilometers along the coast of Queensland. It consists of more than 600 coral islands. Some of them are true coral islands, other are the tops of submerged mountain ranges covered with lush tropical growth
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. Only the south-east and south-west corners of the continent have a temperate climate. The northern part of the country, with a tropical climate, has vegetation consisting of rainforest,
Pine trees Short Leaf Pine Tree Pine Tree Pine Tree Types Pines are among the most well-known coniferous trees in the world. They thrive in temperate mountainous regions, but can also survive in tropical spots in the northern hemisphere. Among the most popular types of Pine trees are: ·Scotch Pine: Commonly found in North America where it is commercially grown as a Christmas tree, the Scotch Pine is known for its beautiful bluish-green needles and full shape. ·Ponderosa Pine: Popular among landscapers, the large Ponderosa can grow up to 80 feet tall. Its pyramidal shape and long needles make it an excellent choice for a windbreaker on large properties. ·Bristlecone Pine: Known for its long life, the Bristlecone is among the shortest types of Pine trees. On average
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
cubs safely. But most of these animals get into zoo's in their childhood and when they are grown-up, they can't be put back in the wild-life, cause they cant manage to get food on their own etc. And the places, where the poachers hunt these animals, should be guarded, that the poachers would be captured. Deforestation Also, deforestation is dangerous to animals. Deforestation means, when trees are often cut down, to produce furniture or something else. When the trees are cut down, animals have no place to live or hide themselves from the hunters, so many of them become extinct. Trees, including forests play an important part of the air, that we breathe, cause they produce oxygen, so the less trees and plants, the less oxygen. But there are often held planting campaigns, where people plant their own tree and during a few years, the trees are high
private law. The continued independence of Scots law, the Scottish education system, and the Church of Scotland have all contributed to the continuation of Scottish culture and Scottish national identity since the Union. Although Scotland is no longer a separate sovereign state, the constitutional future of Scotland continues to give rise to debate. Hisory of Scotland ! The history of Scotland begins around 10,000 years ago, when humans first began to inhabit what is now Scotland after the end of the Devensian glaciation, the last ice age. Of the Stone Age, Bronze Age, and Iron Age civilization that existed in the territory, many artifacts remain, but few written records were left behind. The written history of Scotland largely begins with the arrival of the Roman Empire in Britain, when the Romans occupied what is now broadly England and Wales and the Scottish Lowlands, administering it as a
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 have either moist continental climates or dry subtropical climates. There are two different types of grasslands; tall-grass, which are humid and very wet, and short-grass, which are dry, with hotter summers and colder winters than the tall-grass prairie. In the winter, grassland temperatures can be as low as -40° F, and in the summer it can be as high 70° F. There are two real seasons: a growing season and a dormant season.

Canada has many mountain ranges. In the east there are the Appalachians, Torngats and Laurentias. In the western region there are the Rocky, Coastal and Mackenzie ranges and Mount St. Elias and the Pelly Mountains in the northern regions. The vast majority of mountains in Canada lie in the western provinces of British Columbia and Alberta and the Yukon territory. Mountains can be found all over British Columbia while those in Alberta are mainly concentrated on the eastern side of the Canadian Rockies. The Saint Elias Mountains in the Yukon hold some of country's highest mountains, including the highest, Mount Logan at 5,959 metres. The Appalachian mountain range extends from Alabama in the southern United States through the Gaspe Peninsula and the Atlantic provinces, creating rolling hills indented
climate with a mild and rainy winter. Average summer high temperatures across Canada range depending on the location. On the east and west coast average high temperatures are generally in the low 20s °C , while between the coasts the average summer high temperature range between 25 °C to 30 °C with occasional extreme heat in some interior locations exceeding 40 °C 8. Animals and plantlife Canada has wide variety of animals that can be found in the mountains, plains, in rivers and lakes and even in people's back-yards. 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
until 1919. Under Russian rule the Palace of Kadriorg was built and the park was laid out. The National Awakening in the middle of the 19th century brought rapid advances in the Estonian education system, general living conditions and culture. The national epic "Kalevipoeg" was published, theatre and music societies appeared and the 1st Song Festival was held in Tartu in 1869. Since then the Song Festivals have become a national tradition, being held every 4-5 years. This all lead to Estonia's independence on 24 February 1918. In June 1940 Estonia became a part of the Soviet Union. On 20 August 1991 the Republic of Estonia was restored without any bloodshed. CULTURE? National emblems. The Estonian blue-black-and-white national flag was originally the flag of the Estonian Students' Society, consecrated in Otepää Church in 1884. Today there is a memorial plaque on the church wall commemorating the event.
with an average elevation of about 50 metres above sea level. South-eastern and eastern parts of Estonia are higher than the western parts. The relief of the present-day landscape was shaped during the Ice Age. Ice sheet has carried large boulders and limestone blocks here, not to mention that the hilly terrain in Estonia was also shaped by the continental ice and the melting water. The land is rising 25 cm every one hundred years. In folklore, many features of the relief are explained by the activities of giants such as the legendary national hero Kalevipoeg. The Haanja and Otepää Uplands are particularly rich in Hills. It is here that You find Big Egg Hill, the highest point in the Baltic states with 318 metres above sea level. 4. Land regions The northern coast features a steep limestone bank, the Baltic glint, which is one of the world's most important denudations of Ordovician sedimentary rocks. The
The Iberians brought their metal working skills and the first real civilization to Britain in the 3rd millennium B.C. And were then overrun by the various Celtic tribes that begun in the 8th century B.C. The Celts introduced the tribal organization and an early form of agriculture before they were forced westwards to Cornwall, where the Celtic language still exists in different forms, by the Roman invasion begun in 43. AD. The Romans ruled Britain for over two hundred years and left behind three things of importance: their roads, the sights of important cities notably London, and the seeds of Christianity. The Latin way of life villas, arts, language and political organization all vanished, however after the invasions from Northern Europe by the Anglo-Saxons and Jutes from the 5th century onwards. These pagan peoples' were easily converted to Christianity and the preachers from Rome brought with them learning and civilization.
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

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. Rare insect hit by housing scheme Britain's rarest beetle, the streaked bombardier, could soon become extinct in the UK when a new housing development is built over the single site at which it can be found, a brownfield site on the Thames Estuary in East London. "It is very sad that a deliberate choice has been made to plough on with the development, regardless of the consequences to wildlife," said Jamie Roberts of the invertebrate conservation group Buglife. A last ditch attempt is being made to move the beetles to a specially designed pile of rubble that replicates their existing habitat and which has been constructed adjacent to the new development
Estonia has many rivers but only nine of them are longer than 100km. The most important ones are Pärnu River and Emajõgi River Climate Estonia lies in the northern part of the temperate climate zone and in the transition zone between maritime and continental climate. Because Estonia is continuously warmed by the Gulf Stream it has a milder climate despite its northern latitude. Northern latitude means long summer daylight hours (the longest summer day stretches to 19 hours), and dark winters when daylight lasts sometimes only six hours. Being on the Baltic Sea the country is subjected to sea breezes and humidity. Estonia has a temperate climate, with four seasons of near-equal length. Summer is warm, while spring and autumn can be mild. Winter, which lasts from November to middel March, 4 can be very cold. The cold winter does not necessarily mean constant snow; in fact snowfalls are few and far between
4 On the territory of the USA the mountain ranges stretch in the north-south direction. The first from the east are the Rocky Mountains. West of the Rockies lie vast plateaus and tablelands: the volcanic Columbia Plateau, the Great Basin, the Colorado Plateau. Further west is a narrow belt of the Cascade Mountains, and the Sierra Nevada Range Still further west lies an area of valleys. The forests cover 30% of the US. In the southern part of Alaska grow coniferous trees, notably spruces and firs. Around the Great Lakes and New England are mixed forests of pines, maples, elms, birches, oaks and beeches. Along the Gulf of Mexico grow magnolia, red and black gum, cypress and mangrove. Geographical Regions The territory of the United can be divided into eight regions: 1) New England; 2) the Mid-Atlantic region; 3) the South; 4) the Midwest; 5) the Southwest; 6) the Rocky

At the same time a young relative of his, Angela, is brought to the castle by his sister to be kept away from flirting with a lower class man. Also, his sister tells Lord Emsworth to meet with the man and tell him that if they should marry, Angela will not have any money that she inherited for another 4 years. So he goes to London to meet him. While speaking with him, he gets on the subject of pigs and finds out that the man used to be a pig caller. So he teaches Lord Emsworth the universal pig call, which is supposed to call any pig to its manger and make it eat. After hearing it Lord Emsworth rushes out without even speaking a word on the matter he was sent there. During the trip back he falls asleep and forgets the call.
