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. Canada has about two million lakes and they cover about 7.6% of Canada's land. The biggest lakes in order by their surface are Lake Huron, Lake Great Bear, Lake Superior, Lake Great Slave (which is also the deepest), Lake Winnipeg, Lake Erie and Lake Ontario. There are also a lot of rivers in Canada. The longest river is the Mackenzie River which is 4241 kilometers long. It runs through the Northwest Territories. Other large and important rivers are the St. Lawrence River, the Yukon River, the Columbia River, the Nelson River, the Churchill River and the Fraser River. 4. Land regions Mountains Parts of Canada are very mountainous and the tallest mountain in Canada is the Yukon's Mount Logan, which is 6050 meters tall. Canada has many mountain ranges. In the
the world's supply of accessible fresh water. Much of this water is stored in lakes and wetlands that cover about one-fifth of Canada's total area. The Great Lakes--the world's largest surface of fresh water--are shared with the United States and form part of the international border. Other large lakes include Great Bear and Great Slave lakes in the Northwest Territories and Lakes Manitoba and Winnipeg in Manitoba. Mackenzie River is Canada's longest river, which flows 4,241 km from its source to its mouth. With its many tributaries, it drains 1,800,000 square km. The St. Lawrence is the largest river flowing into the Atlantic Ocean. Its drainage basin includes the Great Lakes, forming an inland navigable waterway extending some 3,765 km into the heart of the continent. The longest Pacific-draining river that is wholly within Canada is the Fraser. The Yukon and Columbia rivers, which both rise in Canada,
consist of tiny animals known as polyps that protect themselves by forming and external skeleton of lime and when the polyp dies its shell hardens. When the number of these little creatures increases, fantastically beautiful shapes that we know as corals are form. The Great Barrier Reef can be seen from outer space and is sometimes referred to as the single largest organism in the world. More than 300 varieties of coral ranging from pale blue to bright yellow can be found. Recently, black coral, the rarest type of all, was found on one of the reefs. Lakes Most of the lakes in Australia are filled with water after rains only. Lake Eyre is, on the rare occasions that it fills, the largest lake in Australia and is the lowest point in Australia, at approximately 15 m. The lake is located in the deserts of central Australia, in northern South Australia. Even in the dry season there is usually some water remaining in Lake Eyre, Rivers
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 shield containing the badges of six Australian states, enclosed by an ermine border. The shield is a symbol for the federation of the states, which took place in 1901. The crest, which is above the shield, is a seven-pointed gold star on a blue and gold wreath. The seven points of

Canada's land ranges from fertile agricultural plains in the south to freezing tundra in the north. The southwest of Canada has a mild climate. Cold winters characterize most of the rest of Canada
McKinley with its 6194m. The lowest point is the Death Valley - 86m. Between the mountains are the central lowlands called the prairie and eastern lowlands called the Mississippi valley. One of the most famous mountains in the USA is Mount Rushmore in South Dakota because of the faces of presidents Washington, Jefferson, Lincoln and Roosevelt that have been cut in the rock. Lakes and rivers The Mississippi is the major river of North America and the United States. It flows from north-western Minnesota south to the Gulf of Mexico. It is a significant transportation artery and when combined with its major tributaries (the Missouri and the Ohio rivers) it becomes the third largest river system in the world (at 6,236 km). The western tributaries are the Red River, the Arkansas and the Missouri. The eastern tributaries are the Tennessee and the Ohio. Its name means the Father of Waters in the red Indian
fresh water lakes on Earth. They are sometimes called the inland seas. There are: 1. Lake Superior (the largest and deepest) 2. Lake Michigan (the only one entirely in USA) 3. Lake Huron 4. Lake Erie (smallest and most shallow) 5. Lake Ontario (much lower elevation than the rest). The Great Lakes between the USA and Canada are joined together by rivers and canals. The lakes are connected to the Atlantic Ocean by the St. Lawrence River and to the Hudson River by a canal. Between Lake Ontario and Lake Erie is Niagara Falls (51 m). Another large lake in the USA is Great Salt Lake. It is saltier than the sea. Rivers The Mississippi river is the major river of North America and the United States.

The natural lakes of the interior of continental Australia are salt lakes. Fed by streams and rivers, they receive water rarely. Lake Eyre, Torrens, Frome and Gairdner are the remains of a vast inland sea which once extended south from the Gulf of Carpentaria. Rivers Australia has only few rivers. Many of them are full of water only after it rains. There are many temporary rivers called creeks. The biggest rivers are in the east. All the rivers in Australia are short. Murray River is Australia's principal river. The Murray River and its tributaries run approximately 3,370km in length and form most of the border between New South Wales and Victoria. Climate Because of its size, Australia has many climates. The Tropic Capricorn cuts across the northern part of Australia so about 40per cent of the country lies in tropics. In the south, the island state of Tasmania lies in the cool roaring forties. In the north the climate is tropical
