Q

challenges for human occupation and developmentin norway

A

svalbard is remote
winter darkness
rough sea conditions
extreme temperatures (-30)
fjords in norway are difficult to cross
saami land for development of mining impacts reindeer migration
cc will impact huskie use

17
Q

mitigation strategies in norway/ svalbard

A

well insulated homes
runway painted white
4 by 4s, snow mobiles use
Hardanger suspension bridge
- reduce remoteness, permafrost melting

18
Q

resilience in norway/svalbard

A

Longyearbyen - darkness, low temps, total wilderness surrounds

19
Q

adaptation in norway/ svalbard

A

major hospital treatment fly to mainland
black out curtains
artificial light

20
Q

describe Svalbard

A

most northern island
an archipelago - large group of islands
small population - 2700

21
Q

describe human impacts on alpine areas (the Alps)

A

oil spills in russia
illegal ski developments in bulgaria
120m visitors in the alps
increased tourism = adventure sports etc. = disturbs wildlife, snow cover etc.

22
Q

describe impacts of climate change on the alps

A

ecosystems - high mountain flora/fauna will become extinct
increase in temperatures by 1* pushes treeline down 100m
melting permafrost - communities under threat, increases rock avalanches, mudslides, cable cars, ski lifts unstable
flooding/landslides - meltwater builds up

23
Q

what type of cold environment are the Himalayas

A

Alpine

24
Q

describe impacts of climate change/ human activity on the Himalayas

A

pollution - black cloud arrival
more rain/ less snow = melting accelerates/ flash floods
less snow= less moisture for crops
melting glaciers
95% of glaciers retreating

25
Q

management in the Himalayas

A

ice stupas - 5000 trees planted
water freezes as sprayed on trees = conserves winter meltwater in the summer

26
Q

name glacial landforms in Nant ffrancon valley

A

glacial trough, u shaped valley
ribbon lake - Lyln Ogwen
Cwm Idwal
corrie lake - LLyn Idwal
devils kitchen (back of corie)

27
Q

describe the landscape of Newtondale in North Yorkshire

A

narrow gorge, 80km deep, 5km long
