Australia Australia is located on the Tropic of Capricorn and between the longitudes 110◦ and 155◦ east of Greenwich. It is both a country and a continent covering a total area of over 7.6 million sq. km. On its north and east is the Pacific Ocean, to its west is the Indian Ocean and further down south lies Antartica. Most of the north and the north eastern coast of Australia is...

Vegetation Belts of the World Along the Equator the Sun’s rays fall straight for most of the year which results in a quicker warming of both, the Earth’s surface and the air. As the warm air rises, it is replaced by cooler air. As a result of this cycle there is condensation of water .resulting in heavy rainfall throughout the year. Since the temperature, rainfall and humidity are all high in...

Forests Life would not be possible on the Earth without plants and as such forests make up one of the most important natural resources we have. They not only provide home and food to all kinds of animals, insects and birds but also provide us with wood which is used for a variety of purposes like making of furniture, paper, houses etc. Forests cover almost one third of the land surface...

Crop Rotation     Different types of plants take in different types of minerals from the soil while growing. This makes it necessary to re-vitalise the soil regularly. In the earlier days farmers divided their fields into three parts, they did not grow any crops in one of the three parts in rotation. The objective of this was to allow one of the patches of land to re-vitalise itself during that...

Land Cultivation Breeding of animals and growing of crops was probably one of the initial and most important steps taken by early man. Today land is cultivated to produce food, which includes vegetables, cereals, fruit etc. The types of crops grown depend upon the climatic conditions prevailing in a particular area. In some of the poorer and developing countries the farmers lack modern means of cultivation and as such they are...

Oceans Currents of the World Just as the rays of the Sun warm the air in our atmosphere and create surface winds, the rays also have their effect on the water in the oceans. As we know, the Sun’s rays fall straight at the Equator, this results in a quicker heating of the water in the oceans in that area. As the warm winds blow towards the colder regions, they blow...

Power and Electricity Generation The advancements made by science and technology have not only developed new sources of power but have also increased our dependence upon it. Without power or electricity nothing from our kitchen blender to the heavy industry would work. Electricity can be seen visibly only when the lightning strikes in the skies. Otherwise it is quietly flowing through the wires in our houses in the form of electrons....

Natural Springs of Water Volcanic activity below the Earth’s surface doesn’t only result in eruption of molten lava, it also results in eruptions of hot water springs. In areas where volcanic activity is common, water often seeps into the ground through the rocks and collects underground. Once this happens the underground water gets heated by ground heat and begins to boil. Once the pressure is high enough and steam is built...
