Why is Australia so low in altitude?
NASA noted that Australia was the flattest continent in the world. “Its low average elevation (300 metres) 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.
Why is Australia so flat and dry?
Australia is so dry because we sit under the subtropical high-pressure belt, which encourages the air to push down, preventing the lift required for rain. Being under the high-pressure belt is enough to make it dry, but there are other systems called climate drivers that can make things worse from one year to the next.
