and answers//graded A+
Who governs Antarctica? ✔️✔️correct answer-- as a glob common, Antarctica has
no government
- since 1908 seven nations have made formal claims to parts of Antarctica
- by the end of 1955, a number of countries had created over 20 bases in Antarctica
including US, Argentina and Britain
What is the Antarctic treaty? ✔️✔️correct answer-- The Antarctic Treaty that was
signed in 1961 ensures continued scientific collaboration, prohibits military activities,
safeguards the environment, and holds national claims in temporary suspension
- 28 consultative parties which have the ability to vote on decisions and 19 non
consultative parties which attend meetings but can't vote
Discuss wind in Antarctica ✔️✔️correct answer-- windiest continent on earth
- stirns are commom in Antartica and are frequently very energetic and dramatic
- 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? ✔️✔️correct answer-- 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? ✔️✔️correct answer-- due to the thickness of the
Antarctica ice sheet.
- due to the isolation of Antarctica from other land masses on earth
What impact will climate changes have on Antarctica wildlife? ✔️✔️correct answer-
- parts of Antarctica are warming three times as fast as other parts of the world
- Warner's seas impact the wildlife
- warming Antarctic could attract new species of animals and plants, creating
competition for life that is specifically adapted to icy temperatures
- emperor penguins who rely on sea ice could lose areas of their homes
, - krill face challenges growing and reproducing in waters that are becoming more
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? ✔️✔️correct
answer-- warming climate contributes to ice/ glacier calving. If the ice shelf is
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
What are the 4 main threats to Antarctica? ✔️✔️correct answer-- climate change
- fishing and whaling
- mineral exploitation
- tourism abs scientific research
What impact will fishing have on Antarctica? ✔️✔️correct answer-- Antarctica is
under threat from unsustainable fishing, which disrupts the food chain of the
environment
- overfishing removed viral animals in the already small food chain, such as
overfishing of krill which removes other marine animal food sources
- krill is the most fished marine animal and the majority is Antarctic krill
- despite regulations, there are still reports of illegal, unreported and unregulated
fishing
- the fishing is unsustainable and causes wide scale marine habitat damage
What impact will whaling have on Antarctica? ✔️✔️correct answer-- past events of
whaling are still having detrimental consequences to this day
- even though there are bans on almost all types of whaling, whale population still
stay at reduced and endangered levels
- whales are slow breeders, meaning the ecosystem has been damaged long term
