What are the similarities between Australia and Antarctica?

Answer 1

Some of the similarities between Australia and Antarctica are:

• They are the only two continents completely surrounded by water (sometimes referred to as island continents). They are continents because they each sit on their own tectonic plate, and each is too large to be classed as an island.
• They are the only two continents located completely within the Southern Hemisphere.
• Their interior is quite inhospitable (more so for Antarctica) and largely made up of desert, where precipitation is less than 250 mm per year. They are the world's two driest continents.
• The population density of each continent is very low compared to the size of the continent (In Antarctica, there is no permanent population).

Answer 2

Antarctica's humidity is about five percent, about the same humidity as one would find in any desert.

Answer 3

They are both extremely dry, while Antarctica may be very cold it nearly never rains and there is little moisture in the air, just like an Australian desert.

Answer 4

Both Antarctica and the north pole are permanently covered by ice.

Answer 5

* They are both entirely within the southern hemisphere * They are both entirely surrounded by water * They are the two driest continents * They are the two least densely populated continents
