Geography For Question To Revise Flashcards
Where is Mid atlantic ridge
Mid atlantic ridge (divergant) seperates north america and eurasian plate
Where is san adreas fault
Between north america and pacific transform
Where is himalayas plate
Convergant,Formed by collision of the indian and eurasian plates
Where is ring of fire
convergant)-series of subduction zones around the pacific plate including the andes mountains
Where east pacific rise
Seafloor spreading boundary between the pacific and cocos nazca plates
How are volcanoes,earthquakes found at divergant/constructive,convergant/destructive and trasform/conservative plates
Earthquakes and volcanoes are often found at plate boundaries due to dyanmic interaftion between plates .Earthquakes and volcanoes are often found at plate boundaries as two plate boundaries for example .At divergent/constructive plate boundaries where they move away from eachother and magma rises from the mantle to fill the gap,forming new crust.Volcanoes form,As the magma rises upward from the mantle along the gap between two platesThis new crust can crack and form faults which leads to earthquakes.
while at convergant plates where one plate subducts under one another.This leads to deep ocean trenches to form and lead to the occurance of earthquakes.The volcanoes form as the sinking plate melts as it decends into the mantle,generating magma which rises to the top.
At transform/ conservative boundaries are where the plates are sliding past eachother.The friction of this builds up and they get stuck and it slips releasing lots of seismic waves causing the ground to shake.
What are convection currents?
Convection Currents
* Definition: Circular movements in the mantle caused by heat from the core.
* Importance: Drive the movement of tectonic plates.
How is nuclear power energy generated?
Within the containtment structure, a reactor vessel houses control rods containing radioactive material in the form of pellets of uranium or plutonium. These fuel rods create heat, which is transferred to water within the steam generator. From here, the radioactive heated water is used to heat a separate water system in the steam generator, which is linked to a turbine. The turbine is connected to a generator, which produces electricity from the steam-powered turbines. The steam from this process is then converted back to liquid water in the condenser ready to go back to the reactor vessel to create another cycle.
What are the 7 factors that make a super power country?
Economic Powerr-To ability to project power around the world
Population-More workers and cheaper workers
Size-To hold more people and has more resources
Resources-If a country has a lot of one thing,they hold a high amount of this resource which they can sell to others or even use which leads to economic growth
Military-,more powerful and can be used to excert pressure.
Cultural soft power-appealing a nations way of life,values and beliefs.Through film,clothes and art.
Political power-Countries for example in the UNSC get to make there own choice in europe while as countries like netherlands dont have as much say.
What is development
Development is the growth in the economy,life quality and population in a country which is getting better and better each year
How does globalisation and tncs affect it?
Globalisation increases development as globalisation facillitates the transfer of technology,skills and knowledge from developed countries into developing countries through foreign direct investment,technological alliences and scientific collaborations.It boosts activity,work load and economic growth.Creates more jobs,gives acess to an increase in trade,investment and integration reducing poverty
Tncs affect increase development as they link countries together in the production and selling of goods
Population structure,demographic data,birth rate,death rate,dependancy ratio,fertility rate,infant mortality,life expenctancy,maternal mortality,gdp per capita,human development index,literacy rate
Population structure:The number (or percent) of people in a country in each age group .
Demographic data:All data linked with population changes:birth rate,death rate etc
Birth rate:How many babies are born per 1000 people per year
Death rate:how many people die per 1000 people per year
Dependency ratio:Proportion of people below (0-14) and above (over 65) normal working age,Its calculated by young+elderly divided by working age times 100
Fertility rate:Number of birth a women has in her reproductive life
Infant mortality:Number of children per 1000 live births who die before there first birthday
Life expenctancy:Average number of years a person can expect to live
Maternal mortality:number of mothers per 100,000 who die in child birth
GDP per capita:The total of all money produced per year by countrys workers
Human development index:score between 0-1 which includes literacy,life expectancy and GNi per capita
Literacy rate:How many people can read per 1000 people
What are igos
Inter government organisations (IGOs) are international groups,made up of a number of different countries who play a large part in the making of international laws and regulations this can be to security or trade or even healthcare.
How do igos affect security,trade,environment,economics,healthcare
They impact security as they maintain of international peace and security.They maintain power by applying sanctions,authorising un peace and military use,
They impact trade through helping making trade flow as freely as possible so long as there are no undesirable side effects.To abolish or reduce trade barriers.
They impact the environment as they provide policy makers with regular scientific assesments on climate change,its implications and potential future risks as well as to put formed adaption and mitigation options.
They impact economics as they have 2 groups,one group the international development association provides loans to the worlds poorest countries,The other group the international bank for reconstruction and development gives loans to developing countries.
They impact health as they promote health,keep the world safe and help the vulnerable.To ensure that a billion more people have universed health coverage to protect a billion people from health emergencies,
Causes of a tsunami and impacts
Starts of with a distruption in the sea,this can either be an earthquake or a landslide.This then displaces a huge amount of water.It starts of slow and small but as it gets closer and closer to the shore it starts to pick up high speeds and high tides.The tide falls back on the ocean line and it slows down but then the faster water behind pushes it forward and other waves pile in.
Impact of a tsunami
An impact of a tsunami is a displacement of people,homes and cars destroyed.A huge financial recovery neccesary.
