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.

Temperate deciduous forest -Well-defined seasons with a distinct winter characterize this forest biome. Moderate climate and a growing season of 140-200 days during 4-6 frost-free months distinguish temperate forests. Temperature varies from -15° C to 25° C. Precipitation (750-1500 mm) is distributed evenly throughout the year. Temperate grassland- Semiarid, continental climates of the middle latitudes typically have between 25 cm and 50 cm of precipitation a year. Much of this falls as snow, serving as reservoir of moisture for the beginning of the growing season. Warm to hot summers are experienced, depending on latitude. In the winter, grassland temperatures can be as low as -40° C, and in the summer it can be as high 20° C. There are two real seasons: a growing season and a dor
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. 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.
The continent it fills is called Australia too. So, Australia is both a country and a continent. If you want to make clear that you are speaking about the country, you may call it the Commonwealth of Australia. It’s the official name of the country. Australia is the smallest continent, but one of the largest countries on Earth. It’s 6th largest country. Its area is about 7.6 million sq km. One third of it is occupied by deserts. It’s both the flattest and, except for Antarctica the driest. Neighbouring countries include Indonesia, East Timor and Papua New Guinea in the north, the Solomon Islands, Vanuatu in the northeast, and New Zealand in the southeast. Its capital is Canberra. Other big cities are Melbourne, Sydney, and Brisbane. National language in Australia is English. Monetary unit is Australian dollar. Their national holiday is on the 26th of January
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
as polyp. There are more than 300 varieties of coral, which is a ultimate dream of every shell- collector. There are undersea observations, glass-bottomed boats and water scopes for undersea viewing, as well as skin-diving equipment. The Great Barrier Reef is and ideal place for a sunny holiday. The relief: Australia is an old and low continent with simple relief. Plains cover the greater part of the land. Most of the rocks have turned into sand and there are big sand deserts on the Western Plateau. In the centre of Australia are lowlands which are covered with sedimentary rocks. Deserts cover most of the land in Australia. Most of the deserts lie in the central and north-western part of the country. The deserts in Australia occupy 18% of the continent. The biggest deserts are the Great Victory Desert, the Great Sandy Desert, the Tanami Desert, the Simpson Desert and the Gibson Desert.
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 down for farming purposes. Plants: Trees of this biome include hardwoods such as maple, oak, hickory, and beech. There
selfgoverning homeland called Nunavut, meaning "our land". It is over two million square kilometers and it is inhabited by 17,500 Inuits. 9. Plants The flora of Canada is quite diverse, due to the wide range of ecoregions and environmental conditions present in Canada. From the warm, temperate broadleaf forests of southern Ontario to the frigid Arctic plains of the Northern Canada, from the wet temperate rainforests of the west coast to the arid deserts, badlands and tundra plains, the biodiversity of Canada's plants is extensive. Many of the plants seen in Canada are introduced, either intentionally or accidentally. Canada offers a wide range of habitats across varied vegetation. Arctic Tundra can be found in Canada's north which leads south into boreal forests which is most typical of Canada and covers more of the country than any other type of vegetation. The Maritimes are
