Australia, NASA from Space Satellite Image Square Sticker

Australia, Shaded Relief and Coloured Height Australia is the world’s smallest, flattest, and (after Antarctica) driest continent, but at 7.7 million square kilometres (3.0 million square miles), it is also the sixth largest country. Its low average elevation (300 metres, or less than 1000 feet) is caused by its position near the centre of a tectonic plate, where there are no volcanic or other geologic forces of the type that raise the topography of other continents. In fact, Australia is the only continent without any current volcanic activity at all—the last eruption took place 1,400 years ago at Mt. Gambier. https://earthobservatory.nasa.gov/images/5100/australia-shaded-relief-and-coloured-height. The Earth Observatory is part of the EOS Project Science Office at NASA Goddard Space Flight Centre
