I have never seen a desert, which is strange some 1/3 of the land surface is considered a desert
Even the Antarctic is deemed a desert!
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one-third of the land surface of the world is arid or semi-arid. This includes much of the polar regions where little precipitation occurs and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by
but the particles usually have a negative charge when their diameter is under 250 μm and a positive one when they are over 500 μm.
Physical geography Major deserts.
Deserts take up about one third of the Earth's land surface.
Bottomlands may be salt-covered flats. Eolian processes are major factors in shaping desert landscapes. Polar deserts (also seen as "cold deserts") have similar features, except the main form of precipitation is snow rather than rain. Antarctica is the world's largest cold desert (
