Australia is the smallest continent located in the Southern Hemisphere between 10-44 degrees south latitude and 112-154 degrees east longitude. It was inhabited by Aboriginal Australians for over 40,000 years before being discovered by Europeans in the 17th century. Australia can be divided into three main physical regions - the Western Plateau, Central Lowlands, and Eastern Highlands. The Western Plateau covers most of Western and Central Australia and contains the famous Uluru rock formation. The Central Lowlands contain several inland river basins. The Eastern Highlands run along the eastern coast and contain the Great Dividing Range and highest point of Mt. Kosciuszko. Antarctica is located entirely in the Southern Hemisphere around the South Pole, covering

AUSTRALIA Australia is the smallest of the world’s continents. This is in fact the only country in the world which occupies a whole continen Due to this Australia is also called an island continent . Australia is slightly more than twice the size of India in area . This continent lies wholly within the southern hemisphere .

LOCATION OF AUSTRALIA 1.LOCATION: IN THE SOUTHERN HEMISPHERE 2.LATITUDE: 10° S TO 44° S 3.LONGITUDE:112°E TO 154°E
DISCOVERY OF AUSTRALIA For at least 40,000 years before European settlement in the late 18th century , Australia was inhabited by indigeneous Australians ,known as “ABORIGINES” . Captain James Hook discovered Australia in 1770 . Captain Cook was an English seaman . He landed near the site of the present day Sydney harbour . He named this land after is homeland , the New South Wales . Australia was a british colony for a long time . It became independent on 1st January , 1901 . Australia is divided into a total of six self-governing states and two centrally administered territories .
THE LAND OF AUSTRALIA THE CONTINENT OF AUSTRALIA CAN BE DIVIDED INTI THREE MAJOR PHYSICAL DIVISIONS: 1. THE WESTERN PLATEAU 2. THE CENTRAL LOWLANDS 3. THE EASTERN HIGHLANDS
THE WESTERN . PLATEAU The western part of australia is a vast plateau which covers nearly two –third of the continent it incudes three states of western australia, northern territory and south australia . The average height is about 350 m above sea level . Macdonnnell Range , which is roughly in the centre of australia , incorporates the world famous Ayers Rock . The Australian plateau is rich in number of mettalic minerals such as gold and iron ore . Ayer rock, which is now known as Uluru is an This Photo by Unknown Author is licensed under CC BY
THE CENTRAL LOWLANDS THESE LIE BETWEEN THE WESTERN PLATEAU AND THE EASTERN HIGHLAND . IT EXTENDS FROM THE GULF OF CARPENTARIA IN THE NORTH ACROSS THE CONTINENT TO SOUTHERN SHORES OF AUSTRALIA . THE CENTRAL LOW LAND CAN BE DIVIDED INTO THREE PARTS: 1. THE GREAT ARTESIAN BASIN 2. LAKE EYRE BASIN 3. THE MURRAY-DARLING BASIN
THE GREAT ARTESIAN BASIN It is the largest and the deepest artesian basin in the world covering a total of 1,711,000sq.km . The region is famous for the underground water . The water is often hot and has high salt content . It is very useful for cattle rearing .
LAKE EYRE BASIN This basin lies in the middle of central lowlands . Most of the rivers which flow through this lowland are not able to reach the sea and fall into the inland lakes . Thus a great part of the central lowland around lake eyre is a region of INLAND DRINAGE .
THE MURRAY- DARLING BASIN Murray-darling basin of australia is formed by the two most longest rivers of australia i,e murray darling . Murray-darling basin is australias most important agricultural region which produces rice,oil seeds, wool,cotton.etc.
THE EASTERN HIGHLANDS The eastern highlands extend almost parallel to the eastern cost of Australia. These highlands starting from the Cape York peninsula in the north reach the island of Tasmania in the south . The higher pats of highlands form the GREAT DIVIDING RANGE. Mt.Kosciusko, with a height 2,234metres above sea level , is the highest peak of Australia . Most of the rivers of austrakia rise in the eastern highlands . A special feature of the eastern coast of Australia is
ANTARTICA With the south pole at its heart,Antarctica is the world’s windiest,coldest and most southernly continent. Antartica is the fifth largest continent . Due to permanent snow cover it is also known as WHITE CONTINENT. This Photo by Unknown Author is licensed under CC BY-NC-ND
LOCATION AND SIZE ANTARTICA IS LOCATED AROUND THE SOUTH POLE . IT LIES COMPLETELY IN THE SOUTHERN HEMISPHERE.
DISCOVERY OF ANTARTICA ANTARTICA WAS DISCOVERED IN 1820 . BUT ITS REAL EXPLANATION BEGAN ONLY IN THE 20TH CENTURY . INDIA ESTABLISHED A PERMANENT BASE CAMP AT DAKSHIN GANGOTRI FOR THIS PURPOSE.SEVERAL OBSERVATION STATIONS HAVE BEEN ESTABLISHED BY OTHER COUNTRIES .
LOCATION OF ANTARCTICA 1.LOCATION: SOUTH POLAR REGION(BEYOND ANTARCTIC CIRCLE) 2.POPULARLY KNOWN AS: A WHITE CONTINENT 3.AREA:14 MILLION SQ.KMS 4.TEMPARATURE:-90°C AT VASTOCK
