Tallinna Tööstushariduskeskus Saturn Referaat Tallinn 2014 Sissejuhatus Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky ("Astronomy for Kids"). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today
...................................................................60 17.3 How Does Oil Impact The Environment?................................................................60 3 ENERGY STORY Once upon a time, in a town not far away, there was an 8th grader who was afraid of the dark. Her name was Jules. She was also afraid of the quiet, and of the cold. So she always left on the lights, the TV, and stereo even when she had her I-Pod earbuds on. She took lots of very long, hot showers. She never walked anywhere, but got rides from her mom in a big SUV. She couldn't be happy unless she was using all the energy she possibly could for all the stuff around her. Her friend, Les, didn't like to use any energy at all. He walked to school, read books instead of watching TV, played the trumpet instead of Guitar Hero, and turned off the lights anytime he left a room. Then one evening, there was a power outage
The last supernova in our own galaxy exploded in 1604, rivaling Jupiter's brightness in the night sky and deeply impressing Johannes Kepler, the pioneering astronomer. A nearby supernova--within a few light-years--would bathe the Earth in lethal radiation. Yet the legacy of supernovas is as close as our own bodies. The carbon in our cells, the oxygen in the air, the silicon in rocks and computer chips, the iron in our blood and our machines--just about every atom heavier than hydrogen and helium--was forged inside ancient stars and strewn across the universe when they exploded billions of years ago. Eager to understand our origins and, in some cases, simply wild about things that go bang, astronomers have been struggling for decades to understand why stars that shine peacefully for millions of years suddenly blow up. Lately they've had two big breaks. One is a revelation about potent blasts of high-energy gamma rays that come from distant points in the heavens
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. Nitrogen is created by biological fixation, and phosphorus is created by precipitation.
Australia had the British flag as their official flag until 1901, when the Commonwealth of Australia was formed. Over 30 000 entries attracted the official competition. Five of them, which contained almost identical designs, were placed equally first. The Australian flag symbolises Australia's historical links with Britain, because it has British flag on it, and Australia's location in the southern hemisphere, because it has stars of the Southern Cross on it. The large seven-pointed star represents the six original states and the territories of Commonwealth. There is also the Indigenous Australian flag, which represents the Aboriginal Australians. The flag with its colours of red (representing the land), black (representing the people) and the yellow in the middle (representing the sun) is a source of pride for Indigenous Australians. The present coat of arms was granted by King George V in 1912. It consists of a
Some renewable energy technologies are criticised for being intermittent or unsightly, yet the market is growing for many forms of renewable energy. Climate change concerns coupled with high oil prices, peak oil and increasing government support are driving increasing renewable energy legislation, incentives and commercialization. New government spending, regulation, and policies should help the industry weather the 2009 economic crisis better than many other sectors. Costs Renewable energy systems encompass a broad, diverse array of technologies, and the current status of these can vary considerably. Some technologies are already mature and economically competitive (e.g. geothermal and hydropower), others need additional development to become competitive without subsidies. This can be helped by improvements to sub-components, such as electric generators. The table shows an overview of costs of various renewable energy technologies
Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir
ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution
Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another.
In 1788 on the 26th of January the first fleet arrived at Botany Bay and established a penal colony near modern-day Sydney. Geographical Position Australia is located in the 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 2880 km from the mainland of Asia and is almost half way round the world from Europe. More than 9 600 km separates it from America. Australia lies between the Pacific and Indian oceans. The Timor Sea and the Arafura Sea separate Australia from Indonesia. In the north the coast is washed by Great Australian Bight and the Indian Ocean. In the northeast the Coral Sea washes the coasts and in the southeast there is the Tasman Sea which also separates Australia from New Zealand. The biggest island is Tasmania which is located to the south of the country.
GLOBAL WARMING Global warming is the observed century-scale rise in the average temperature of Earth's climate system. Since 1971, 90% of the increased energy has been stored in the oceans, mostly in the 0 to 700m region. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850. More than 90% certain that most of global warming was being caused by increasing concentrations of greenhouse gases produced by human activities.In 2010 that finding was recognized by the national science academies of all major industrialized nations.
Australia Australia is the smallest continent in the world. It is 7.6 million square kilometres big. It is often called the island continent because it is rather small for a continent and very big for an island. There are only five countries bigger than Australia in the World. There are five states in the mainland. Tasmania is also considered as a state so there are six states. The Northern Territory and Canberra are also independent but they are not states. Canberra is the capital of Australia and it is situated between Sydney and Melbourne because both of these cities wanted to be the capital. The population is about 19 million people and growing. New South Wales is
circuit, made up of three parts: a power source, a pair of parallel rails and a moving armature. Along the pair of parallel conducting rails a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. Railguns have long existed as experimental technology but the mass, size and cost of the required power supplies have prevented railguns from becoming practical military weapons. However, in recent years, significant efforts have been made towards their development as feasible military technology. For example, in the late 2000s, the U.S. Navy tested a railgun that accelerates a 3.2 kg projectile to hypersonic velocities of approximately 2.4 kilometres per second, which is about Mach 7. In addition to military applications, railguns have been proposed to launch spacecrafts into orbit; however, unless the launching track was particularly long, and the acceleration required spread
Territory). The Australian people are culturally the same as the Anglo Americans. There also live aborigines. Aborigines are the ancestors of the people. Like the US and Canada, Australia was an English speaking colony of Great Britain. 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
The stem has frozen, typically in an eastward orientation. The stem and leaves lose their green color. The wild sunflower typically does not turn toward the sun; its flowering heads may face many directions when mature. However, the leaves typically exhibit some heliotropism. Cultivation and uses A sunflower farm near Mysore, India. Sunflower heads solds as snacks in China. Sunflowers are native(pärit) to the Americas. The earliest known examples of a fully domesticated sunflower were found at the Olmec site of San Andrés dating some time before 2500 B.C.[1] The Incas used the sunflower as an image of their sun god. Gold images of the flower, as well as seeds, were taken back to Europe early in the 16th century. The Giant sunflower (Hlianthus giganteus) is native to Connecticut. They can grow to be between 3 and 12 feet tall. Their flower heads can be between 2 to 3 inches wide. They
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. Cultural diversity makes Canada even more interesting. In spite of this, in recent years there is a strong movement in French-speaking Quebec to become an independent country.
The average rainfall is 30 to 60 inches a year. In deciduous forests there are five different zones. The deciduous forest has four distinct seasons, spring, summer, autumn, and winter. In the autumn the leaves change color. During the winter months the trees lose their leaves. The animals adapt to the climate by hibernating in the winter and living off the land in the other three seasons. DesertDeserts cover about one fifth of the Earth's land surface. Deserts temperature ranges from 20 to 25° C. The extreme maximum temperature ranges from 43.5 to 49°. Hot and Dry Deserts usually have very little rainfall and concentrated rainfall in short periods between long rainless periods. Most Hot and Dry Deserts don't have very many plants. The only animals they have that can survive have the ability to burrow under ground. They only come out in the night when it is a little cooler.
Teaduslik revolutsioon 15431600 I One of the most important developments in the western intellectual tradition was the Scientific Revolution. The Scientific Revolution was nothing less than a revolution in the way the individual perceives [ tajub ] the world. As such, this revolution was primarily an epistemological revolution it changed man's thought process. It was an intellectual revolution a revolution in human knowledge. Even more than Renaissance scholars who discovered man and Nature, the scientific revolutionaries attempted to understand and explain man and the natural world. Thinkers such as the Polish astronomer Nicholas Copernicus(14731543), the
Age 15 is legally a "young person" not a "child". Age 16 is a school leaving age. They can leave home, drive a moped, marry with "parents' consent" buy beer. Age 17 can drive a car. Age 18 can vote, get married, drink in pubs. Education is a very important part in the life of British youth. One can't become an independent person without it. When time comes to enter a college a young Englishman chooses one far away from home. It is a necessary part of becoming adult. During the last 30 years there were a lot of different trends in youth movements. All of them were characterized by their own philosophy, way of life, style of dressing. Each tendency was born by the influence of economic and political changes in the society. Those trends are known as the "hippies" the "punks" the "rockers". But certainly there are different traditional youth organizations in Great Britain. Among them -- the Scout Association, the Girl Guides Association, the National Union of
Australia is a country and also a continent. If someone wants to make clear, that he is speaking of the country, he may call it by its full name of Commonwealth of Australia. 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
Australia's capital is Canberra, the only city with its own territory. It was built in the early 1900s just to be the capital. The official language is English and the official name of Australia is the Commonwealth of Australia. Australia is located on the Southern Hemisphere (because of that Australia is also called "A land down under"). 2 . Geographical position Australia is an island continent and it is located between the Indian and South Pacific oceans south east of Asia. From the north it is bordered by the Timor Sea and the Torres Strait. From the east by the Coral Sea and the Tasman Sea. Australia's coastline is about 37,000 km long. The Great Australian Bight washes the southern coast. The Gulf of Carpenteria and the Cape York Peninsula surround it in the south. 3. Relief Australia is the smallest continent in the world It is often called the island continent because is too big for
20,0 million and most of the people live in bigger cities: Sydney (4.2 million), Melbourne (3.7 million), Brisbane (2 million) and in Canberra, Which is also the capital of Australia. National language in Australia is english and the monetary unit is Australian dollar. Australia is divided into 6 states and 2 territories. Symbols Australia has a British Union flag. It is red, white and blue. Five small stars represent the constellation Southern cross. The big star represents country's states and territories. In 1901 the flag was chosen from about 30000 entries in a public contest. It was officially adopted as Australian flag in 1953. 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.
THE IMPORTANCE OF THE RAINFOREST The beauty, majesty, and timelessness of a primary rainforest are indescribable. It is impossible to capture on film, to describe in words, or to explain to those who have never had the awe-inspiring experience of standing in the heart of a primary rainforest. Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest
SCIENCE AND TECHNOLOGY A century ago communication across any distance was dependent upon the telegraph or letters. No jets crossed the ocean, no television pictures enabled us instantly to see events in any part of the world, there were no worldwide telephone networks and no computers. It is just a short lifetime since humanity first travelled into space and discovered how fragile our planet looks. FROM FIREWORKS TO THE MOON At first glance you might think that there couldn't possibly be anything common between a 13 th century festival in China and the Apollo 11 moon landing in 1969. However, there is a link and that is that they both relied on the use of rockets. The Chinese first developed rockets by filling bamboo tubes with an explosive made from saltpetre, charcoal, and sulphur
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. British Columbia is in the landform region called the Western Cordillera. ('Cordillera' means a system of mountain ranges). Between the mountain ranges are areas of high plateaus and deep trenches. Since the landscape is very rugged, most people live in the south and near the coast. Vancouver and Victoria are the largest cities in British Columbia. The region includes the Queen Charlotte Islands and Vancouver Island. All these islands are peaks of a mountain range that is partly covered by the Pacific Ocean. The St Elias Mountains in the Yukon include Canada's highest peak, Mount Logan

We have successfully climbed the tallest mountains, sailed the greatest seas, and defeated the mighty dinosaurs. But we are no match for nature's greatest weapon: Natural Disasters. As far as natural disasters go, the deadly trinity of mudslides, whirlpools, and meteors is man's greatest nemesis. Mudslides strike without warning and with deadly force. Every day, across the world, unsuspecting villagers are hammered by the force of 36,000 tons of that soft wet dirt known as mud, as it cascades down mountains, rolls across plains, swoops through valleys, and takes flight over cliffs. Once the mud strikes, it leaves the villages and cities in ruins, as houses and other structures are quickly destroyed. And just as every day these villages are leveled by these disastrous attacks, the world's top scientists are working relentlessly to come out with a plan for the prediction and prevention of these horrible assaults.
Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a lot of energy inside them. Physics of wave energy
Introduction The United States of America is a very big country. Its territory is about 9.4 million square kilometres and its population is more than 260 million people, 12% of them are the Afro-Americans. It is the world's third-largest country by size and by population. The population density is about 27 people per square kilometre. Most of the people live in towns. There are 50 states in America. The biggest of the state is Texas, next by size are California, Alaska and Montana. Six states - Maine, Vermont, New Hampshire, Connecticut ,Rhode Island and Massachusetts are called New England. They are all small states in the U.S
This is a bad argument, because the conclusion does not follow from the premises. Logic is the science of correct reasoning. Logic helps us in constructing and evaluating arguments. How to recognize an argument? Generally a passage contains an argument if it attemps to prove something. It requires evidence presented (premise(s)) and a claim that is said to follow from the alleged evidence (conclusion). This inferential relationship might be explicit or implicit. The relationship between the premises and the conclusion might be explicitly expressed thanks to words that serve as indicators to distinguish the premises from the conclusion. Conclusion indicators Swans are birds and birds have wings. Therefore, swans must have wings. The word “Therefore” indicates the conclusion which are claimed to follow from the premises. Other conclusion indicators include: - consequently - thus - so - hence - it follows that - it implies that

Prior to this momentous event that heralds an evolutionary transformation in the life of plants, the planet had already been covered in vegetation for millions of years. The first flower probably did not survive for long, and flowers must have remained rare and isolated phenomena, since conditions were most likely not yet favorable for a widespread flowering to occur
change is the increase in carbon dioxide concentrations in the atmosphere. The main cause of that is the burning of fossile fuels. This is leading to the global warming. People have discovered a way to reduce the amount of CO2 in the atmosphere. It is possible to seperate the CO2 from the other gases by adding liquid which is very good at absorbing CO2. Then it can be pumped to underground. Scientist came up with this idea because methane gas has been down there for thousands of years and it has not come up. So they expect that the CO2 won't be coming up either. To be sure of that, they are coing to make a test and drill two wells to take purified CO2, inject it into the ground and monitor the physical changes that CO2 undergoes. This technology is really new and it is unknown to people. It has not been proven yet, so people are scared and concerned about it. The biggest fear is that carbon dioxide will
