Approximately how old is the Great Dividing Range?

• A. 100 million years
• B. 200 million years
• C. 300 million years
• D. 400 million years

Answer: (C)

The Great Dividing Range, which spans over 3,500 kilometers along the eastern coast of Australia, is an ancient mountain range that has been shaped by geological processes over millions of years. It is widely believed to have formed approximately 300 million years ago during the late Paleozoic era, making it one of the oldest mountain ranges in the world. This process involved the uplift of sediments and volcanic activity, followed by extensive erosion that has continued to shape its current features. Given its estimated age of around 300 million years, this answer reflects the geological history and the significant role the Great Dividing Range plays in Australia’s landscape, ecology, and climate. The range is not only a distinguishing topographical feature but also a critical watershed and biodiversity hotspot, influencing weather patterns and serving as a habitat for a diverse array of plant and animal species.
