Extreme Weather event caused by a High Pressure System

heatwave

We used the 2017 European heatwave and the effects it had. (The revision resources to the Low Pressure event you need to know about can be found here Hurricane Haiyan).Use the powerpoint to find photos of an article we read and links to online resources.

Simply put you need to revise:

1.The causes of the heatwave. You will talk about anticyclones (high pressures)and air masses.

2.The effects of the heatwave. As normal categorise this into social economic and environmental. But also look at how different groups of people were affected.

3.How people responded to the heatwave

The effects of leisure on a location and how people manage it

Green-Traveller-3This is what the syllabus asks you to know How urban and rural areas are used for leisure.

  • Advantages and disadvantages of leisure use for both local residents and leisure users.
  • The impacts of increasing leisure use on rural honeypots.
  • Positive and negative impacts of major sporting events on localities.
  • Study of one location where leisure use is managed and the effectiveness of the
    management strategy.

 

We have studied Lyndhurst in the New Forest as a honeypot site and the Rugby world Cup as a sports event (we also looked at the Glastonbury festival which is excellent on managing the impacts in a sustainable way.)

The information on Lyndhurst is here  lyndhurst information and here  lyndhurst new forest honeypot . The Rugby world cup was straight from the text book

The homework you were asked to do on Glastonbury is here. Glastonbury Festival homework

Use your notes and work in your exercise books as well. Break down the ideas into

1/ advantages and disadvantages of the leisure activities (ie their impacts) and you could also look at whether these are social, environmental and/or physical.

2/ How people have managed these issues. what strategies have they used to improve the situation?

Rural to Urban Migration in LICs

Historical_global_urban_-_rural_population_trends

(image from Wikipedia)

People move to cities from the countryside in LICs for a variety of reasons. These can be split into push and pull factors

  • Push factors drive you away from a place
  • Pull factors attract you to a place

Examples of push factors (with added in extensions and chains of reasoning to explain them)
1/ Poor harvests so lack of food leads to malnourishment / early death
2/ Desertification so land is becoming less fertile harder to make profit from farming harder to feed family / malnourishment
3/ Lack of education / schools so children have to walk long distances to school remain illiterate do not get employment skills
Examples of pull factors (with added in extensions and chains of reasoning to explain them)
1/ More education opportunities / higher education so children can complete education become fully literate gain employment skills
2/ More job opportunities which may also be better paid so money can be sent back to rural families (called remittances)

Other push and pull factors include: natural disasters, modern facilities and living, poverty, war, being with family, persecution, lack of farming land

Revision Task

Categorise these factors above into push and pull and write a couple of sentences for each of them that extends and explain s them better using chains of reasoning

8 mark questions – how to answer them

mock-exam-sign

Firstly practice practice practice answering them. Ak you teacher for some. Look at mark schemes work out what you need to include. Redo questions if you don’t get full marks until you do. I’ve used this in class with my groups. It may help.

Underneath that are a couple of possible questions for you to start practicing on.

1/ ‘Are physical factors are more likely to cause flooding in rivers than human factors’.
Explain your opinion. [8]

2/ read the question below

8 mark Q MNC

Multinational Companies: are they a good thing or not?

Multinational corporations (MNCs) are very large global companies which have their headquarters in HICs but often manufacture their products in LICs, where the production costs are lower. When MNCs locate within LICs they can bring a number of advantages to the local community, but they can also bring negative impacts.

  • They create stable employment and regular income for their local employees. This in turn leads to increased spending, and a number of other benefits to the local community – this is known as the multiplier effect. (see photo below)
  • They often help to develop the local infrastructure including roads, water and power supplies.
  • They bring foreign investment which means the local economy is improved without using taxpayers’ money.
  • They may also contribute to social welfare projects including improving health and education.
  • Workers are often exploited with poor working conditions, long hours and low pay.
  • Health and safety standards are lower than in HICs, resulting in workers being exposed to a higher risk of accidents.
  • The higher-paid managerial positions often go to foreign workers.
  • Profits mainly go back to the country of origin rather than being used to improve the local area.
  • Environmental regulations are often less restrictive in LICs, resulting in air, water and land pollution, and loss of wildlife habitats.

Revision task: a) categorise these effects into negative and positive as well as into social environmental and economic b) read these notes on Nike to see how one example fits into this overall pattern Nike revision notes

The Multiplier Effect

Also remember the videos we have watched on the Rana Plaza disaster in Bangladesh and how that shows poor working conditions and non-existent workers right/health and safety at work

So the BIG question is: Do you think MNCs are a good thing or not?

Revising for the field work exam – Paper 3

Jurassic_Coast_web

You need to know, understand and skilfully use these words to be able to do well in Paper 3 of your exam; the field work paper

Key Term Meaning
Primary data collection Information you have collected yourself
Secondary data collection Information someone else collected
Qualitative data Information that is NOT expressed as numbers or numerical data, eg as present or absent, feelings, or as colours.
Quantitative data Information that is expressed in numbers
Spatial sampling Either points along a line (linear of line sampling) or using a quadrat
Random Sampling Where every person or place has an equal chance of being measured. Decisions are made using random number tables
Stratified sampling Dividing sampling into groups, eg three sites from each section of coastline, or five people from each age range. It is possible to combine stratified sampling with random or systematic sampling
Systematic sampling Collecting data in an ordered or regular way, eg every 5 metres or every fifth person.
Opportunistic sampling Where you make decisions in the field or on the day based on the conditions you find there
Accuracy of data collection Ensuring all data is collected correctly
Reliability of data collection Ensuring all data is collected consistently

 

Revision tips:

1/ What are the differences between the last two key words?

2/ What are the advantages and disadvantages of each type of sampling technique? A recent 6 mark exam question was Evaluate the strengths and weaknesses of systematic sampling for collecting pedestrian flows.” So to help revise you could replace “systematic” with any of the other sampling strategies from the table and practice that as a 6 mark question.

Global Atmospheric Circulation

bbc atmosphere

This title makes this sound a difficult topic to revise, but it isn’t. firstly, global = over the whole world, then atmospheric = to do with the atmosphere and finally, circulation = moving around. In other words its how and why the atmosphere moves around the Earth. And once you know this you can then link it to the ecosystems topic, as global atmospheric circulation controls a lot of world climates which of course influence different BIOMES. (The two biomes we studied are: semi-arid and tropical rainforest.)

Firstly remember that

Rising air cools as it rises, so it cools, water vapour will cool, clouds will form and therefore three is a HIGHER CHANCE OF PRECIPITATION IN AREAS OF LOW PRESSURE (sometimes called depressions)

Descending air warms and therefore there is no condensation and LESS CHANCE OF PRECIPITATION IN HIGH PRESSURE AREAS (sometimes called anticyclones)

Since it is hotter at the equator, air rises here and creates area of low pressure. (So there is a lot of rainfall here. This is where you get tropical rainforests.) This risen air spreads out from the equator, cools and descends around 30 degrees north and south of the equator (area of less rainfall so deserts and semi-arid biomes here). This paragraph describes the movement of the Hadley cell which you can see in this diagram; it is labelled 1.

Additionally the rest of the global circulation is very well explained by this American teacher to his class. You need only watch up to 4:00 minutes.

Once you think you understand this global circulation, test yourself and use p. 75 from the revision guide to link global atmospheric circulation to biomes. If you need some more help with this you can read p. 210-11 in New Wider world.
