The Australian continent

It is only 5% (144.55 million square kilometers) of the world's land area, but it is the sixth largest country in the world after Australia, Russia, Canada, China, the United States and Brazil. It is also the only country among the six major powers surrounded by water.

Australia is the smallest continent in the world. It is also the lowest and most flat (except Antarctica) is the most dry

The highest point in the mainland of Australia is Mt. Kosiosko in New South Wales state with an altitude of 2,228 m. The lowest point is the dry seabed of Ayr Lake in South Australia, 15 meters above sea level.

The mainland and Tasmania are surrounded by thousands of small islands and numerous large islands. Nearly 40% of the coastline's length includes the coastline of the island. As an island country, the coastline plays an important role in determining the boundaries of the country, state and territory.

Nearly 20% of the land in Australia is classified as desert. In addition to low annual average rainfall, the amount of rainfall in Australia has also changed. The rainfall pattern is concentric with the vast dry core of the mainland and shows high rainfall intensity in the tropics and some coastal areas.

Climatic zones range from tropical rain forests to deserts, and cold forests to snow-covered mountains.

In this climate, our plants and animals evolved geographically in an isolated continent, experiencing a slow drying climate with constant height change. Therefore, the uniqueness of most parts of Australia's flora and fauna is due at least in part to these characteristics of our climate.

A powerful Malay flowing through the Australian continent is another example of human activity against the river. The Murray River is a typical river on the Australian continent. The river supplies irrigation water and supports continental farmers. It is the longest river and regional life in the continent. But slowly, it seems it is falling by excessive use and incision formation keeping the water level to a minimum.

As part of all major supercontinent, the Australian Continent began to form after the Permian Gondwana division, and the continental land was separated from the Africa continent and the Indian subcontinent. In the Permian it began to depart for a long time from Antarctica and spread to the Cretaceous. When the last glacial age ended around 10,000 BC, sea level rise formed the bus strait and separated Tasmania from the mainland. Then between 8000 BC and 6,500 BC lowlands were submerged in the sea, separated from New Guinea, the Al Islands and the mainland Australia. The Australian continent is currently moving to Eurasia at a rate of 6 to 7 cm per year.

Australia is a formerly Australian Commonwealth and a sovereign state consisting of Australia mainland, Tasmania and many other small islands. It is the largest country in Oceania, the sixth largest country in the world with total area. Neighboring countries are north to Papua New Guinea, Indonesia, East Timor, Solomon Islands, Northeast Vanuatu, and southeast New Zealand. 25 million people are highly urbanized, mainly concentrated in the eastern coastal area. The capital city of Australia is Canberra, the biggest city is Sydney. The other major metropolitan areas of the country are Melbourne, Brisbane, Perth and Adelaide.
