Antarctica is a land mass covered in ice and snow. How deep can the ice reach?
200meters
400 meters
4800 meters
7000 meters
The coastal regions around Antarctica have a high level of marine nutrients. What are the reasons for this?
High level of storms
Nutrient input from rivers
Fertilizer run off from land
Coastal upwelling
Ice helps with controlling global temperatures. Which statement is correct?
Ice has a low albedo and so will reflect UV back out to space and less is absorbed and converted into IR
Ice has a high albedo and so will reflect UV back out to space and less is absorbed and converted into IR
Ice has a high albedo and so will reflect IR back out to space and less is absorbed and converted into UV
Ice has a Low albedo and so will absorb UV and reflect IR back out to space
How might warmer global temperatures affect glacial movement in Antarctica
Glaciers could move more slowly towards oceans due to melt water making less heavy.
Glaciers could move more rapidly towards oceans due to melt water acting as a lubricant.
Glaciers could move more rapidly towards oceans due more snowfall
Glaciers could move more slowly towards oceans due thicker sea ice holding them back
How might a decrease in ozone affect Antarctica
Less UV absorbed in the stratosphere which can then ionize phytoplankton affecting food webs.
Less UV absorbed in the troposphere which can ionize phytoplankton affecting food webs
Less IR absorbed in the stratosphere which can then ionize phytoplankton affecting food webs.
Less IR absorbed in the troposphere which can ionize phytoplankton affecting food webs
What are the risks to Antarctica from tourism
New diseases brought in from humans
Invasive species brought in from boats
Waste such as faeces, plastics and oils.
Taking photos and raising awareness
Which species is most affected by a reduction of Ozone
Phytoplankton and Krill
Krill and small fish
Small fish and penguins
Penguins and leopard seals
Which two resources are currently exploited from Antarctica
Minerals
Oil
Krill
Fish
Which one of these are not affects of global warming
Ozone depletion
Glacial movement
Ice shelves breaking up more frequently
Area of sea ice increasing
Which one of these is not a reason for Antarctica's importance
Carbon sequestration by phytoplankton
High Albedo
Control of global sea levels
Terrestrial food webs
Marine food webs
How does Krill contribute to controlling climate. Pick Two.
Populations of krill photosynthesise storing carbon in their tissues
Krill consume phytoplankton and store carbon in their tissues
Krill respire releasing carbon dioxide into the sea
Dead Krill and faeces contains carbon which can sink to the deep, acting as a carbon sink.

Conservation of Artic marine life resources
Conservation of Antarctic marine living resources
Commission of Antarctic mainland life research
