Antarctica's landscape is proof that it has one of the highest levels of precipitation in the world. true false

False

Explanation:

Antarctica's landscape is anything but a proof of high levels of precipitation. This continent is actually the driest continent in the world, and it is considered as being a polar desert. The precipitation levels are actually lower than those of the Sahara Desert. The landscape may give the wrong impression, as pretty much everything is covered with ice and snow, and we know that the snow is part of the precipitation, while the ice only forms from water. Still, it is a totally different case, the amount of snowfall is very low, but because of the strong winds, it is constantly dispersed all over the continent, similar to the effect the wind has with the sand in the deserts, so most of the snow is actually very old. Also, very big percentage of the ice comes from the ocean water, as well as from the water bodies that were once in liquid form when the continent was still not frozen.
