AVON, CT SNOWSTORM THE CATSKILLS, NY HURRICANE JOPLIN, MO TORNADOES video TUSCALOOSA, AL TORNADOES NASHVILLE, TN - FLOODING HISTORY Story begins in the early 1920s with an inventive scientist named Samuel Ruben and Philip Rogers Mallory During World War II, for instance, Ruben devised the mercury cell, which packed more capacity in less space and was durable enough for the harsh climates of wartime theaters like North Africa and the South Pacific--places where ordinary zinc carbon batteries used in flashlights, mine detectors, and walkie-talkies couldn't hold up. P.R. Mallory manufactured millions of mercury cells for the war effort. The Mallory Battery Company was formed shortly thereafter. And in 1950s they improved that battery, making it more compact, durable, and longer lasting. And now they are the world's leading producer of high-performance alkaline batteries.

Both English and French are official languages at federal level. Canadas economy is heavily reliant upon its abuntant natural resources and upon trade with the USA. Canada is one of the world`s wealthiest nations with a high per capita income. It is a free market economy with much less government intervention than European nations. Canada is one of the few developed countries that is a net exporter of energy. Canada has deposits of natural gas and oil. Also it is world`s largest producer of zinc and uranium. Canada has world`s most liberal social policies. Medial marijana is legalized. And also in 2005 they legalized gay marriage, so Canada became one of the four nations that allow same- sex marriage. Canada sent 2000 soldiers to fight in Afganistan, but its relations with the USA were strained when it refused to support the war in Iraq.

other types of mineral resources has grown significantly. In 1996, the top non-fuel minerals were gold with production of US$2.05 billion, copper US$1.47 billion, nickel US$1.45 billion, and zinc US$1.25 billion. There was also significant production of lead and iron. There are about 50 major gold mines in Canada and the country leads the world in technologies which extract gold from rock and soil. The nation is the world's largest producer of zinc and the fifth largest producer of lead. Among the provinces, Ontario is the top producer of non-fuel mineral resources, followed by Quebec, British Columbia, Saskatchewan, and Newfoundland. Each year Canadian companies spend over US$600 million to find or develop new mines and fuel supplies. However, environmental concerns and increased regulation have led many Canadian mining companies to shift exploration elsewhere. Latin America is becoming a favorite choice for Canadian mining companies.
AD 70 The first Roman city was Camulodunum also called Colonia Vitricencis. It was the seat of Roman power and governance of Brittania until sacked during the Boudiccan revolt. Why the Romans came to Britain is not quite certain. Two reasons have been suggested: 1) The Romans were cross with Britain for helping the Gauls (now called the French) fight against the Roman general Julius Caesar. 2) They came to Britain looking for riches - land, slaves, and most of all, iron, lead, zinc, copper, silver and gold. How long did the Romans stay in Britain? The Romans remained in Britain from 43 AD to 410 AD. That is almost four hundred years (four centuries). Why did the Romans leave Britain? Their homes in Italy were being attacked by fierce tribes and every soldier was needed. The River Thames was quick way to transport goods between Britain and the Continent. The Romans saw this and built the town of Londinium around the river's main crossing point. The Romans gave britain:

John's). It's situated in the east of Canada. Population of the whole region is 2,3 million people. The climate is mild, humid and windy. The main industries are fishing, mining and forestry. The most popular landmark is the Appalachians. The North consists of Nunavut (capital Iqaluit), Northwest Territories (capital Yellowknife) and Yukon Territory (capital Whitehorse). These areas have very low density of population. Mining is popular in each of them, mostly they mine gold, zinc, copper and even diamonds there. In Yukon Territory there is the highest point of Canada Mount Logan, which is 5600 metres high. Most of the North is tundra and mostly Inuit live there.
South Australia also produces grapes for use in making wine. Mining. Australia is rich in mineral resources. But roads and railways have to be constructed to the mining sites, so that the mining industry depends heavily on foreign capital. During the 1950's, geologists found huge deposits of coal and iron ore in Australia. Manganese, natural gas and petroleum were discovered in the 60's. Australia has got minerals like: copper, gold, silver, zinc, iron, nickel. Manufacturing. Australia imports more manufactured goods than it exports. The nation has to import many of its producer goods factory machinery, construction equipment and so on. Australia's iron and steel industry produces enough of the metals to meet the needs of other industries. The leading manufactured products are food, cars, paper, chemicals, clothing and shoes. Most of the factories are located in and around Sydney ad Melbourne. Forestry and fishing

Canada is the second largest country in the world. Situated to the north of the United States, in North America, it has both English and French as its official languages. Even though its area is bigger than that of the United States, its population is only about 11% of that of the USA some 35 million. Because of that, Canada has one of the lowest population densities in the world. The capital of Canada is Ottawa the name of whose comes from the old Algonquin language, with the original word meaning `to trade'. Due to the country's huge size and position, it is very diverse. It is bordered by the Pacific Ocean to the west, the Atlantic to the east, and the Arctic to the north. The landscapes differ greatly from rolling plains and mountains to the cold tundra in the northern part of the country. Geographically, the country's split into 5 major regions the Pacific, the Prairie Provinces, Central Canada, the Atlantic Provinces and...

raise cattle and extract oil and gas beneath the ground. From the oceans they take fisk and other seafood. Because Canada is relatively small population and abundant natural resources, much of their international trade is exported. Their most important customer for exports is the USA. Canada exports a lot of food products: wheat and other grains, beef and other meat, oil, dairy products, sugar beets and maple sugar to name a few. Copper, gold, iron ore nickel and zinc are the minerals most often sent to other countries. Natural gas and oil are other important exports along with forestry products. Though largely dependent on natural resources Canada also has a strong manufacturing industry. Transportation equipment, such as automobiles and automobile parts, are their most important manufactured good, followed by food, paper products and chemicals Alice Tärk, 8b.
Australia Australia is the only country in the world that covers an entire continent, yet also the smallest and the driest of all the continents. It's almost the same size as continental USA, being the sixth largest country in the world. It's also the oldest some of the rocks are more than 3,000 million years old. Australia is often called `Down Under', because it lies in the Southern Hemisphere. As a result, its seasons are the opposite of ours. Australia, Tasmania and a number of smaller islands form the Commonwealth of Australia. Because of the country's great size, the climate in Australia ranges from tropical regions of the Northern Territory to the cool temperate conditions in the southeast and Tasmania, where it often snows in winter. In the north, half the year is `wet' and half is `dry'. From November to April heavy rain fills the rivers and makes enormous lakes where thousands of birds come for the summer. From May to Octobe...

Canada has vast deposits of natural gas on the east coast and large oil and gas resources centred in Alberta, and also present in neighbouring British Columbia and Saskatchewan. Canada is one of the world's most important suppliers of agricultural products, with the Canadian Prairies one of the most important suppliers of wheat and other grains. Common agriculture plants are barley, oats, rye and wheat. Canada is the world's largest producer of zinc and uranium and a world leader in many other natural resources such as gold, nickel, aluminium, and lead; many, if not most, towns in the northern part of the country, where agriculture is difficult, exist because of a nearby mine or source of timber. 7.

The Merino wool is also famous all over the world. Australia is also very rich in minerals. Coal, bauxite, old, iron ore, diamonds, natural gas and nickel can be found in Australia. Western Australia has become the most important region of mineral production. Mining is an important branch of Australia's industry too. The famous mining are is broken Hill in New South Wales. It's one of the largest productions of lead, zinc, copper and uranium. Australia is also rich in precious and semi precious stoned. Black opals and pink diamonds are thought to be very valuable. Most of Australia's oil and natural gas comes from fields found in the Bass Strait. Oil has been found in South Australia and Western Australia. Agriculture of Australia depends totally on climate. In the eastern part of the northern Territory peanuts, sugarcanes and fruits are grown. Cattle
including the highest peak , Ben Nevis. Lowland areas, in the southern part of Scotland, are flatter and home to most of the population, especially the narrow waist of land between the Firth of Clyde and the Firth of Forth known as the Central Belt. Glasgow is the largest city in Scotland, although Edinburgh is the capital and political centre of the country. An abundance of natural resources such as coal, iron and zinc contributed significantly to the industrial growth of Scotland during the 19th and early 20th centuries. Today, energy is a major component of Scotland's economy. Whilst Scotland is the largest producer of petroleum in the European Union, the production potential of renewable energy has emerged as an important economic and environmental issue in recent years. Geology and geomorphology !
With gold came new roads, railways and growing cities. On 1 January 1901 all the six separate states of Australia united into one country. Many people left Britain for a new life in Australia. After 1945 people from other European countries, like Italy, Greece, Germany and Holland, began coming to Australia. Since 1945 more than three million people have moved there. Economy Australia is extremely rich in mineral resources like coal, iron, copper, nickel, lead, tin, zinc and others. The forests have much good timber. Along the seashores pearl shell and tortoise shell can be gathered. Australia is one of the biggest producers of diamonds, apals, sapphire, agates. Oil and natural gas have been found in western and southern Australia. Australia has a wide range of industries. Most of them are located in Australia's largest cities which are also ports. Australia produces chemicals, machinnery, motor vehicles, electronic equiptment, paper, textiles,

Scotland and Northern Ireland have long been noted for their production of whisky and textiles, notably tweed and linen respectively. Today Scotland is also a major producer of computers. The leading manufacturing regions are Greater London, Greater Manchester, West Midlands (Birmingham), Yorkshire, Newcastle, Glasgow, Bristol. Britain has relatively few mineral resources. Zinc, tin, iron ore and copper are all produced in small quantities, together with tiny amounts of gold and silver. Non- metallic minerals include limestone, chalk, clay, sandstone, salt and gypsum. Britain has the richest energy resources in EU including oil and natural gas, both primarily found in the North Sea, off eastern Scotland and eastern England respectively. About 77% of the land area of Britain is under agricultural use of some sort. Agriculture employs 2 per cent of the population
The western mountains are especially rich in them. The US is among the leading countries in the value of its mineral production. The US is third, after Russia and Saudi Arabia, in the production of petroleum. Mining has been the key of development of the USA. The US has large deposits of coal, iron ore, natural gas, and petroleum, which are vital to the country's industrial strength. Its many other important minerals include copper, gold, lead, silver and zinc. To meet its needs the US must import additional amounts of iron ore, petroleum, and other minerals. Most American industry is located in the eastern and mid-western parts, around the Great Lakes and also on the Pacific coast. The US engineering products are known all over the world. The US produces planes, rockets, cars, agricultural machinery, ships, etc. Electronics has become a major industry. The role of service and leisure industries has also grown.

Australia is very rich in minerals. Minerals can be found in most states, so it is a vital part of Australia's economy. The leading mineral production area is Western Australia, where gold, uranium, nickel ore and manganese ore can be found. Australia is also rich in precious and semiprecious stones, like black opals and pink diamonds for example. It is said that mining produces 20% of Australia's export. Lead and zinc are also found in Australia in quite large amounts from Mount Isa and Broken Hill. Besides those two, copper, uranium, coal and oil are found in Australia. Most of the goods produced in Australia come from New South Wales. Iron, steel, power cables, jet aircrafts all come from there. Melbourne is known for producing motor vehicles, machinery, food and clothes. Tourism is also an important part of Australia's economy. More than 500000 people work on that profession
