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

masses is converted into kinetic energy of the waves. The coriolis force is a minor one. This force force is caused by the rotation of the earth. Waves which are caused by this force are very long. The wavelength could be about one km. The surface tension works against the two forces mentioned above. The force caused by the tension of the surface is low and provokes more smaller waves. From stresses to waves Waves caused by wind are build over deep waters and energy-rich waves are build in some distance from the equator. If air is moving over water it causes a tangential stress on the surface of the water. These stresses result in a formation of waves. The turbulence in the flow of the air creates rapidly varying shear stresses and pressure fluctuations. If the oscillations are ‘in phase’ with already existing waves a furthermore in wave development occurs.
Its name means ,,Southland". The official name of the country is the Commonwealth of Australia. It's capital is Canberra. Australia is the sixth largest country in the world but the smallest continent. Australia has 6 states and 2 territories (New South Wales, Victoria, Tasmania, Queensland, Western Australia , South Australia, The Australian Capital Territory and the Northern 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
geothermal heat--which are renewable (naturally replenished). In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation),followed by solar hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption. While there are many large-scale renewable energy projects and production, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.Kenya has the world's highest household solar ownership rate with roughly 30,000 small (20100 watt) solar power systems sold per year.
During the summer the sun shines almost 24 hours a day. Summer are usually warm. Average summer temperatures range from 3° to 16°C. TaigaTaiga is the Russian word for forest and is the largest biome in the world. It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. Some of the animals in the taiga hibernate in the winter, some fly south if they can, while some just cooperate with the environment. GrasslandsGrassland biomes can be found in the middle latitudes. They can 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
Firstly i will tal about the origins of the islands and the history, secondly about life on the land and in the sea, finaly about conserving the Galapagos. The Galapagos Islands are situated on junctions between several shifting tectonic plates on the equator and about 1000 km off the Pacific coast of Ecuador. They are the product of one of the most volcanically active regions on our planet, a hot spot is situated directly beneath the islands and also It is the point where major ocean currents meet. These circumstances combine to make an area that truly is like no other place on earth. Galapagos is comprised of 13 major islands, more than 120 smaller islets and rocks, and the surrounding ocean. The total land mass is almost 8,000 sq. km. Highest peak is Wolf Volcano reaching 1707m. The present islands are all younger than 4 million years and were formed separately from other land masses as a result of volcanic eruptions.
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. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summer temperature is 3-16°C. During the brief summers, the top section of the soil may thaw out allowing plants and microorganisms to grow and reproduce. However, these plants and microorganisms become dormant during the cold winter months. Soil is formed slowly. The constant freezing and thawing in the tundra helps to break the rocks into smaller pieces. Permafrost consists mostly of gravel and finer material. The arctic tundra is also a windy place and winds can blow between 48 to 97 kilometres. The tundra is basically like a desert when it comes to precipitation
.................................. Factfile Australia is the only country in the worlf that fills the whole continent. The continent is also called Australia, if you want to make clear that you are speaking about the country you may call it by its official name: Commonwealth of Australia. Australia is the smallest continent, but one of the largest countries in the world. Its area is about 7,6 million sq kilometers. Its population is about 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
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
CANADA Geography Canada is the world's second largest country in total area after Russia , since it covers nearly 10 million square kilometres, but is one of the most sparsely populated, with only about 34 million inhabitants. The majority of them live within 300 kilometres of Canada's southern border. Much of the rest of Canada is uninhabited or thinly populated, because the country has a rugged terrain and severe climate. Canada extends across the continent of North America, from Newfoundland on the Atlantic coast to British Columbia on the Pacific coast and northward into the Arctic Ocean. Canada shares land borders with the United States to the south and north-west. Canada is a land of great variety
Protecting endangered species will make a difference in humans' life In the nature of humankind it is natural to hunt animals. However, nowadays hunting endangered species will make humans be just killers, because it is not necessary to kill something just to have a trophy on the wall at home. People can be proud of what they have done, but decreasing the population of a species largely will cause the specific animal breed to go extinct faster than it would happen via natural causes. Therefore, humans should stop hunting endangered species to slow down their extinction, as these species
6. Deforestation: Our forests produce fresh oxygen and help in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and making that land available for residential, industrial or commercial purpose. FIND OUT 5 WAYS HOW TO STOP DEFORESTATION. 7. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton. Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to burning of fossil fuels or erupting volcanoes or rotting vegetation which release sulphur dioxide and nitrogen oxides into the atmosphere

Bacteria a) Heterotrophic bacteria, eg. symbiotic and non - symbiotic N2 fixers, ammonifier, cellulose decomposers, denitrifiers b) Autrotrophic bacteria, eg. nitrosomonas, nitrobacter, sulphur oxidizers, etc; 2. Fungus; 3. Viruses 4. Actinomycetes and stretomyces; 5. Algae eg. BGA, yellow gree algae, golden brown algae. 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

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 Melbourne) and Tasmania (capital Hobert)
No trees grow in the tundra so houses can not be made from wood unless it is transported from elsewhere. However, during a large part of the year, the cold part, there is a lot of snow in the tundra. And it turns out that snow can be a very good construction material. In the winter, Inuit lived in round houses made from blocks of snow called "igloos". In the summer, when the snow melted, Inuit lived in tent-like huts made of animal skins stretched over a frame. Although most Inuit people today live in the same community year-round, and live in homes built of other construction materials that have to be imported, in the past Inuit would migrate between a summer and winter camp which was shared by several families. Getting Around To travel from one place to another, Inuit used sleds made of animal bones and skins pulled over the snow and ice by dogs. Strong dogs with thick fur like huskies, bred by Inuit, were used. On
The official name of the country is the United Kingdom. The United Kingdom is an island country. It consists of the island of Great Britain and Northern Ireland. Great Britain can be divided into three parts England, Wales and Scotland. Each of them has their own capital city. Glasgow in Scotland, Cardiff in Wales and London in England. The country is situated in the north-western Europe. The territory of the United Kingdom is about 244,000 square kilometres and about 60 million people live there. The UK contains a number of small islands. The largest islands that belong to the United Kingdom are the Isle of Man in the Irish Sea and the Isle of Wight which lies off of England's southern coast. The largest groups of islands are the Shetland Islands, the Orkney Islands and the Hebrides. Geographical Position The UK is situated in the Northern Hemisphere. The United Kingdom is bordered by the Atlantic Ocean in the west, the North
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 with a territory of about 10 million square kilometers and it is bordered by three oceans: the Arctic, the Pacific and the Atlantic 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

Project ESTONIA MAP OF ESTONIA Southern Viljandimaa The southern part of Viljandi county catches the eye with its sublime scenery. The area today lies in the very heart of the historical Mulgimaa the home of hills, deep valleys and lakes brought together by a beauty spot Halliste primeval valley. According to several folk tales, it is also in these valleys, woods and bogs that Old Nick found refuge.The great variety displayed in the nature is also reflected in the local cultural heritage. At the beginning of the 19th century growing linen spread and became the basis of the legendary wealth of Mulgi farms. The ancient barn-dwellings and decaying manor houses are the mute witnesses of those times
Tallinn English College Topic Estonia Tallinn 2008 1. Introduction Estonia is a small country about the size of Switzerland, or New Hampshire and Massachussetts combined. Estonia is named after the people called "Ests" who lived in the region in the 1 st century AD. The Republic of Estonia is one of the three countries commonly known as the "Baltic States". The other Baltic States are Latvia and Lithuania. 2. Geographical position Estonia is situated in northeastern Europe. Estonia is bounded on the north by the Gulf of Finland, on the east by Russia, on the south by Latvia and on the west by the Baltic Sea. In the north it borders on Finland. The coastline of the Baltic Sea in Estonia is characterized by numerous gulfs and bays, the biggest of them being the Gulf of Finland, the Gulf of Riga and the Gulf of Pärnu. Bays include the
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
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"
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
Norther Europe’s environment" by Britt Aniansson. Oceans and seas are polluted every day by different substances that reach the waters from different sources on land and at the sea. The author points out four main problems in the marine environment. One of the main problems is the chemical pollution which is caused by natural or man- made halogenated compounds, pesticides, dioxins, chlorinated organic materieals and so on. These compounds are causing deformage in marine animals and are storaged in their fatty tissues. They have also been found in organisms throughout the world oceans because they are dispersed quickly by winds and currents. Another problem that affects the marine life is excess phosphorus and nitrogen flow into the sea from towns, factories and other man-made sources which cause intense algae growth. Algal blooming consumes large amounts of dissolved oxygen and in areas with poorer water
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 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

6. What is the role of wildfires in the temperate grassland plants’ lifecycle? Wildfires play a very important role. They allow the grasslands to be open and free of trees and shrubs. Any seedling of a tree that appears is killed off by the intense heat. If the fire does not clear out the seedlings, the grasslands would become a shrubland changing forever. Remarkably, the plants in the grasslands have adapted to the wildfires that come through, and actually need them to keep healthy and grow new vegetation in the spring 7. How are plants adapted to life in temperate grassland? (vt. ka õpik lk 61) During a fire, while above-ground portions of grasses may perish, the root portions survive to sprout again. Some prairie trees have thick bark to resist fire. Prairie shrubs readily resprout after fire. Roots of prairie grasses extend deep into the ground to absorb as much moisture as they can Extensive root systems prevent grazing animals from pulling roots out of the ground

Effects of Marine Oil Spills Oil spills can have a serious economic impact on coastal activities and on those who exploit the resources of the sea. In most cases such damage is temporary and is caused primarily by the physical properties of oil creating nuisance and hazardous conditions. The impact on marine life is compounded by toxicity and tainting effects resulting from the chemical composition of oil, as well as by the diversity and variability of biological systems and their
Estonia is a small country in Northern Europe with an area of about 45 000 sq km. The country's climate is determined by the proximity of the Atlantic Ocean. The summer temperatures are a little lower than the average of that latitude, but the winters are considerably warmer. As a part of the East-European Plain, the country has a rather flat surface. The highest and most topographically variagated region in Estonia is in the south-eastern part of the country. The Sakala Upland plains offer contrast to the hills of Ottepää, Karula and Haanja. At 318 metres, Suur Munamägi ('Great Egg Hill') is not only the highest point in
Only one country in the world fills a whole continent. That country is Australia. The continent it fills is Australia, too. Australia, then, is both a country and 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. Sixty million years ago Australia and its nearby islands were separated from the rest of the world by a great upheaval. They were cut off from Asia by the ocean. Very few people and almost no animals visited Australia before English colonists began to settle there in 1788. During all those 60 million years the native Australian mammals developed by themselves, undisturbed by the animals developing elsewhere. Australia is the only continent except Antarctica that is all south of the equator. It's name means "southland". Since it is south of the equator, its seasons are just the opposite of ours. It
