Restless earth-case studies Flashcards
What is your fold mountain case study and where is it located?
The alps and its located in Central Europe
How was the fold mountain formed?
The African plate collided with the Eurasian plate causing the rock in the geosyncline to be folded up into a mountain range.
What are human uses of the fold mountain case study? (Explain)
- Tourism-hotels and money income
- Farmers-plant crops on the fold mountain
- Businesses- hydroelectric power
- Industries- logging the coniferous forest
How have people Adapted to living on fold mountains?
Farmers buy in fodders crops and pasture livestock on the valley bottoms each year instead of moving everything up to the high pastures each summer while hay grows on the bottom floor
-railway tunnels have been cut into the mountains to make travel much easier
Fields cultivated for crops in summer
What’s your super volcano case study and where is it?
Yellowstone and its located in the USA in Wyoming
What are 3 characteristics of a super volcano for example Yellowstone?
- Ejects 1000x more compared to a normal volcano
- not a usual cone like structure it occurs in large depressions called calderas
- they are over 10x the size of a regular volcano
What are the likely effects of a super volcanic eruption such as yellow stone?
- 25 mile high ash cloud
- everything within a 100 mile radius will be destroyed
- the ash cloud will lower temperatures by 20c
- the uk will receive the ash cloud 5 days after the eruption
- global economy placed under huge pressure and will probably collapse
- people, home and wildlife will be destroyed
What is your volcano case study and where is it?
Mt merapi located in the south east of Asia on a destructive plate margin at a subduction zone
What’s so special about mt merapi?
Part of the Pacific ring of fire
Cause of the volcano eruption?
The indo Australian plate being subducted beneath the Eurasian plate
What are the primary effects of a volcanic eruption such as mt merapi, what will be effected and how?
- volcanic bombs and hot gasses up to 8000c will spread (wildlife people) the hot temperature will burn people alive and the wildlife around it
- pyroclastic flow down the volcano(people’s homes, towns wildlife) - destroy and burn down homes and workplaces destroying the lives of humans
- Sulphur dioxide spreading as far as south Australia (people) - harm humans bodies killing them
What are the secondary effect of a volcanic eruption such as mt merapi, what will be effected and how?
- prices of food increases- because of loss of crops- people will starve because they can’t afford it- effects local people and business owners
- emergency shelters for the homeless- effects the homeless- gives the somewhere to live for now
- ash rock and lava will be washed down by rainfall creating lahars (mudflows)
Positive impacts of a volcanic eruption and how are they positive?
- fertile soil to help grow crops better
- the dramatic scenery brings in tourism providing much needed income to the country
Negative impacts of a volcano eruption?
- people are dead or injured
- risk of diseases spreading because of overcrowding due to so many left homeless
- loss of jobs and homes
Short term responses to a volcanic eruption?
- volunteering/military help out
- international aid such as the Red Cross
- evacuation centres
