The Great Dividing Range is the fifth longest mountain range in the world, and it exists in Australia, of all places. Australia is pretty well known for being a relatively tectonically stable continent, with no nearby tectonic rifting or subduction-related events occurring. As a result of this, orogenies, the term used to describe mountain building processes, should, in theory, not be occurring here. But yet here it is, this spectacularly large mountain range not only exists, it stretches from the very tip of Queensland, all the way south through New South Wales, where it then bends east as a result of some tectonic activity that has occurred here, before straightening out somewhat, and stretching down in Victoria, where it then suddenly, and, somewhat unexpectantly, turns west where is stretches towards the far western parts of Victoria, through the Central Highlands where Ballarat, Creswick, Daylesford, and Ararat occupy, before finally ending at the Grampians.

In this video, we'll get an idea of the tectonic processes that led to the formation, and continual uplift of this mountain range. We'll go all the way back to the very beginning, around 550 million years ago, and work our way up to point when the Great Dividing Range first began life. We'll also explore the weird western bend that occurs in Victoria, and discuss why this mountain ranges stretches so far west.

New Zealand, unsurprisingly, has some part to play here. But, a fact that is perhaps surprising to many, is that so does Antarctica. And you'll understand why by the end of this video.
