How big is Australia: Territorial data and hotspot analysis of the world’s sixth largest country
As the sixth largest country in the world, Australia's vast territory and unique natural environment have always been the focus of global attention. This article will combine hot topics in the past 10 days to provide you with a detailed analysis of Australia's area data, geographical features and recent hot spots.
1. Basic data on Australia’s area
| Project | data |
|---|---|
| land area | 7,692,024 square kilometers |
| Territorial sea area | About 58,000 square kilometers |
| coastline length | 25,760 kilometers |
| Maximum span between east and west | About 4,000 kilometers |
| Maximum span between north and south | About 3,700 kilometers |
2. The relationship between recent hot topics and the area of Australia
1.climate change impacts: Australia has recently experienced extreme weather, with record high temperatures in many places. Scientists point out that Australia's vast size means the impacts of climate change vary significantly in different regions.
| area | recent temperature anomalies |
|---|---|
| new south wales | 3-5℃ higher than normal |
| Western Australia | Some areas exceed 45℃ |
| Tasmania | Relatively mild, but unusual precipitation |
2.Mineral resource development: Australia’s huge land area contains rich mineral resources, and the development of lithium mines has become a hot topic recently.
| Minerals | Global share of reserves | Main producing areas |
|---|---|---|
| iron ore | about 30% | Pilbara region of Western Australia (approximately 500,000 square kilometers) |
| Lithium ore | about 25% | Greenbush mining area in Western Australia, etc. |
3.Aboriginal land rights: Recently, the High Court of Australia made an important ruling on Aboriginal land rights, involving traditional territories covering an area of 1.2 million square kilometers.
3. Comparison of Australia’s area
| Comparison object | Area (square kilometers) | Proportion to Australia |
|---|---|---|
| Australia | 7,692,024 | 100% |
| China | 9,596,961 | About 1.25 times |
| USA | 9,525,067 | About 1.24 times |
| Brazil | 8,515,767 | About 1.11 times |
| India | 3,287,263 | About 42.7% |
4. Australia’s geographical features
1.Terrain distribution: Australia has mountains in the east, plains in the center, and plateaus in the west. Its area distribution is as follows:
| terrain type | Proportion of area occupied |
|---|---|
| plain | about 44% |
| plateau | about 33% |
| Mountain | about 23% |
2.land use: Although Australia is large, its available land is limited.
| land type | Area (10,000 square kilometers) | Proportion |
|---|---|---|
| agricultural land | 397.9 | About 51.7% |
| forest | 125.3 | About 16.3% |
| desert | about 140 | About 18.2% |
5. Recent social hot spots
1.immigration policy debate: Australia’s vast area and sparse population (only about 26 million) are in sharp contrast. The recent adjustment of immigration quotas has triggered heated discussions.
2.wildlife protection: The koala habitat area has decreased by about 30% in the past 20 years, and a recent protection plan has been introduced.
3.Renewable energy development: Australia’s vast desert areas are being planned as large-scale solar farms, with a total area expected to exceed 2,000 square kilometers.
Conclusion: Australia’s area of 7.69 million square kilometers gives it a unique position in the world. Recent hot spots show that how to rationally utilize this huge land resource and balance development and protection has become an important issue facing Australia. From climate change to the energy transition, from Aboriginal rights to immigration policy, every decision Australia makes is closely linked to its size.
