For those who don't know....

The largest desert in the world is not the Sahara!! Granted it does measure a massive 3.5 million square miles, but it is dwarfed by Antarctica at 5.5 million square miles!

Antarctica??? I hear you say, "Theres no sand in Antarctica!!" Well no, no there is not, but then sand is not a prerequisite for a desert.

Deserts are defined as: Arid regions, generally receiving less than ten inches of precipitation a year, or regions where the potential evaporation rate is twice as great as the precipitation.

Now then, Polar regions, such as Antarctica, are also considered to be deserts because nearly all moisture in these areas is locked up in the form of ice.

So.... Mr "It makes no difference to me" quizmaster, you were, as I pointed out, WRONG!!
