Australia's Geographic Features

In addition to Antarctica, Australia is the most dry continent in the world. About 35% of the continent has very little rain so it can be classified as desert.

The largest desert in Australia is the Great Victoria Desert and the area spanning Western Australia and South Australia is 348,750 square kilometers. The next point is the Great Sandy Desert in Western Australia, with an area of ​​267,250 square kilometers. The total area of ​​the desert is equivalent to 18% of the total area of ​​the continent of Australia.

In September 2008, the Australian earth science used the data from the National Terrain Database to recalculate the length of the longest 10 rivers in Australia. According to the calculation, the longest single river in Australia is the Murray river of 2,375 kilometers.

The Malay River and its tributary Darling River are the main rivers in the Murray-darling Basin. This basin contains most of the lowlands of Australia, accounting for over 1 million square kilometers, or about 14% of Australia.

The longest river in Australia is the Malambidji River in New South Wales, and its length is 1,485 km.

The continent of Australia is actually the largest island in the world and is often referred to as the continent island. There are thousands of small islands around Australia, more than twice the outcrop to the Australian metropolitan area. Most of it is Melville Island in Northern Territory, its area is 5,786 square kilometers.

Fraser Island, close to the coast of Queensland State, is the fifth largest island in Australia, but the world's largest sand island

In Australia, the Pacific, the Indian Ocean, the Northern Sea, and several large coral and Timor Seas, as part of the area outside, there are several continents over 1000 square kilometers.

Despite the popularity of Australia at the bottom of the world in the Southern Hemisphere. Indeed, Australia is the lowest continent in the world in terms of altitude. The average altitude is only 330 meters. The highest point on the other continents is more than twice the height of Kosiuszko which is the highest mountain in Australia.

Uluru is Australia's most iconic geographical feature, the world's largest boulder (single rock formations). This famous sandstone layer is in the south of Northern Territory (NT) and West of Simpson Desert. It was officially named "Ayers Rock" by a European explorer, but the traditional land owner named it "Uluru". Ulur covers more than 10 square kilometers and 3 square kilometers around its base and has a height of 345 meters. From the erosion of the surrounding mountains, an alluvial alluvial fan was created. Later, it was compressed by rising seawater 500 million years ago and formed a new rock formations. Four hundred million years ago, the seawater disappeared and the land slowly began to fold. This is caused by the terrain force, whereby the rock layer tilts at its end. A bald mountain of Kata Tjuta is thought to be beyond Uluru.

Appendix 1 is a topographic map of South Tanunda in South Australia. The main function of this map is the colors and symbols used to display specific geographic features. A legend will help explain this information. It is very important to note that all functions have different functions and some functions represent their true form. The main point data on the map is the height of the building and site. As you can see, these points can take nearly any form, but they need to be similar to the points on the page. The same symbols can be used for different data, but the colors of buildings and huts are different. Because they are closely related, mapmakers tried them all in triangles, but the building was black and the hut was red
