Questions from this subtopic
Each one with the model answer underneath.
- 1
Name three threats to the Arctic tundra.
Model answer
Climate change, mineral and hydrocarbon exploitation, and growing tourism.
- 2
Give two ways oil and gas extraction damages tundra.
Model answer
Roads, pipelines and drilling pads destroy vegetation that recovers extremely slowly, and spills contaminate soil and water that cannot flush clean.
- 3
Why do vehicle tracks persist in tundra for decades?
Model answer
The vegetation mat is thin and slow-growing, and once it is broken the exposed dark soil absorbs heat and thaws, deepening the rut.
- 4
Explain the risk that a warming climate poses to Arctic infrastructure.
Model answer
Buildings, roads and pipelines were founded on ground that was permanently frozen, and as it thaws the ground subsides and the structures fail.
- 5
Name two indigenous peoples of the Arctic.
Model answer
The Inuit of Canada and Greenland, and the Sami of northern Scandinavia.
- 6
Give two ways indigenous livelihoods depend on the tundra.
Model answer
Herding reindeer or hunting caribou, and fishing and hunting marine mammals along the coast.
