Question 12

why is Antartica so cold and dry

Answer 12

elevation- ice built up on top of continental landmass.mount Vinson highest peak in antraritca with 160000 feet.
heat transport -sea surface temperatures below 3.5 limit warming of overlay.
also, albedo effect causes energy deficit.
continentality - lots of the train is far away from the sea so moist air masses are far away.
solar radiation- low angle of incidence
changes period of day.
