How were the Great Dividing Range formed?

The Great Dividing Range in Australia was formed through a combination of tectonic activity and erosion over millions of years. The range stretches along the eastern coast of Australia for approximately 3,500 kilometers.

The initial formation of the Great Dividing Range can be attributed to tectonic forces, specifically the collision of the Australian and Pacific tectonic plates. Around 300 million years ago, these plates began to converge, resulting in intense pressure and folding of the Earth's crust. This process, known as orogeny, caused the formation of a mountain belt that eventually became the Great Dividing Range.

Over time, erosion played a significant role in shaping the range. The forces of wind, water, and ice gradually wore down the mountains, creating valleys, gorges, and other distinctive features. Rivers and streams carved their way through the range, further shaping the landscape.

The Great Dividing Range is characterized by a diverse range of landforms, including peaks, plateaus, and escarpments. It serves as a significant watershed, with rivers flowing eastward towards the Pacific Ocean and westward into the interior of the continent.

Overall, the formation of the Great Dividing Range is a result of both tectonic activity and erosion, creating a unique and important mountain range in Australia.
