Australia, which appears to be an unchanging continent, is imperceptibly migrating north towards Asia at a very unexpected pace. Scientists have established that the continent is shifting by 2.8 inches (7 cm) annually as per reports that is equal to the way human fingernails grow. Although this movement may seem inconsequential in the short term, after millions of years, it will cause gigantic geological alterations, reshaping the terrain, climate, and variety of the continent in ways that may have lasting consequences.
Overall, Australia’s gradual drift towards Asia is a geological process that will reshape not only the continent but the natural and technological face of the world as well. Though gradual, these changes have far-reaching implications for everything from biodiversity to infrastructure.
The science behind Australia’s northward drift and future collision
The revelation of Australia’s northward drift is not new. Professor Zheng-Xiang Li, a geologist at Curtin University, explained in 2009 that the process is part of a normal natural, cyclical process whereby continents are drifting apart and ultimately will collide. It is something that occurred time and again throughout Earth’s history, and Australia’s collision with Asia ultimately is merely another episode in this ancient geological history. According to Professor Li, “Whether we like it or not, the Australian continent is going to collide with Asia,” that is, that this gradual movement cannot be halted.
Australia’s northward drift and its impact on biodiversity
Australia’s drift resulted from plate tectonics, a geological process that has built Earth’s continents over a period of hundreds of millions of years. Australia separated from Antarctica approximately 80 million years ago in anticipation of its slow migration to the north. The continent has been moving steadily in that direction for the past 50 million years on the Indo-Australian Plate. Scientists predict in the future that the plate will eventually collide with the Eurasian Plate, forming a significant geological and environmental event. The impact will likely cause earthquakes, mountain building, and volcanic activity but effects will spill over into the biological landscape. The biodiversity of Asia and Australia will also be severely impacted. Biodiversity
Australia’s drift causing impact on the future collision on biodiversity
Australia is renowned for its unique and varied wildlife, including famous animals like kangaroos, wombats, and the platypus.
When Australia crashes into Asia, the two very different continents’ ecosystems will eventually conflict. The different species on each continent will most likely compete for resources, and new plant-animal interactions between the two continents can result in the creation of entirely new ecosystems. Some species can learn to thrive in the new environment, but others can go extinct, so the collision is a biodiversity turning point for the whole world.
Australia’s shift and its impact on technology and infrastructure
This Australian shift is not a distant occurrence. It is already having real-world effects on modern technology and infrastructure. In 2016, scientists discovered that Australia’s shift had moved its entire GPS coordinate system 1.5 meters (4.9 feet) off its original position. As a result, the country had to adjust its official coordinates by 1.8 meters (5.9 feet) to remain accurately positioned. This shift highlights the requirement of monitoring the continent’s drift constantly and updating the navigation system accordingly to be accurate. As Australia continues drifting northwards, there will be ongoing issues with technology upgrades.
Navigation systems, satellite maps, and infrastructure dependent on accurate geographic coordinates will require recalibration on a regular basis to avoid errors. This is particularly crucial in industries like autonomous cars, precision agriculture, and aviation, where small errors have significant consequences. In these sectors, even slight misalignments in position can disrupt operations, and therefore, it is essential to have the systems recalibrating on a constant basis.
