Questions And Answers

- winds largely katabatic, this is a result of cold air forming over the people and

falling. (As colder air os heavier)




Why is Antarctica so dry?


✓~ - high plateau of East Antarctica is a desert with less than 50mm of

equivalent falling per year, this does not fall as snow but as tiny ice crystals in

the air.




Why is Antarctica so cold?

What impact will climate changes have on Antarctica wildlife?

, ✓~ - parts of Antarctica are warming three times as fast as other parts of

the world

- Warner's seas impact the wildlife

competition for life that is specifically adapted to icy temperatures

acidic from absorbing carbon


- threats to wildlife like penguins and wales that rely on Krill as their main food

source




What impact will climate change have on Antarctica physical climate?

exposed to warmer air above or warmer water below, there will be more rapid

melting of the shelf.

- sea level rise is the most expensive consequence of global climate change, can

cause global flooding


- co2 released into atmosphere that is stored in ice sheets, which causes global

temperatures to rise more, enhancing global warming on Antarctica

, - albedo effect is lessens due to less ice sheets, meaning more heat is absorbed

into oceans

- mineral exploitation


- tourism abs scientific research




What impact will fishing have on Antarctica?

overfishing of krill which removes other marine animal food sources

unregulated fishing
