well, wikipedia says: "Deserts generally receive less than 250 millimetres (10 in) of rain (precipitation) each year.[1]<http://en.wikipedia.org/wiki/Desert#cite_note-EG-1> Semideserts <http://en.wikipedia.org/wiki/Semi-arid_climate> or steppes are regions which receive between 250 millimetres (10 in) and 400 to 500 millimetres (16 to 20 in)." and states that the biggest desert on earth is the antarctic desert (quite different setting from what one usually thinks about by the term desert, isn't it?) For mountains it seems indeed relative, although the UN has a universal definition for "mountainous environment" (also from WP), any of these: - Elevation of at least 2,500 m (8,200 ft); - Elevation of at least 1,500 m (4,900 ft), with a slope greater than 2 degrees; - Elevation of at least 1,000 m (3,300 ft), with a slope greater than 5 degrees; - Elevation of at least 300 m (980 ft), with a 300 m (980 ft) elevation range within 7 km (4.3 mi). cheers, Martin
