Describing Patterns and Using Locational Knowledge

A common question in the exam is to describe the pattern or distribution of something on a map. 

Many people lose marks on these questions due to poor exam technique. There are two things that can help you:

1. Make sure you know what distribution or pattern means and what words to use

Distribution = the way in which something is spread over an area

Pattern = they way in which something is arranged or sequenced

As you can see they are quite similar. You need to identify whether there is any overall arrangement or repeating sequence or shape to what you are looking at. Good words/phrases to use include:

Exam Technique - How to Describe

So, I thought it would be a good idea to write some posts on specific aspects of exam technique. Having marked many many exam questions over the years I am convinced that knowing what to do in the exam is just as important as revising information. Obviously you need to know the information first before you can apply it to the exam, but just revision alone is not enough for a top grade.

Understanding command words is key. Even the simplest one can be misunderstood. Let's start with 'DESCRIBE'. This is one of the most straight forward things that you could be asked to do. However, many people make mistakes with this command word and end up losing easy marks.

The Man who Set Himself on Fire

Another Strangers episode for you here, this time relevant to the geography of war and conflict. This was one of the most interesting episodes of Strangers I'd heard in a while (even though they are all great so it's hard to chose! btw I don't work for them in case you were wondering but they really do brighten up my commute!!).

Play Dough Volcano Models!

You're never too old for play-dough, even at A2, so the last few lessons of term we decided to use it to learn about our two volcanic eruption case studies: the 2002 eruption of Nyiragongo and Eyjafjallajokull.

The challenge was to not only model the volcano but make a scene of what took place and annotate it with the nature, impacts and responses to/management of the event. Check out the models my students made! It was boys vs girls, can you guess who made which?

Here is Eyjafjallajokull with its huge plume of ash and fissure eruption. They decided to leave out the overlying ice cap as it was difficult to model, I think the newspaper round the sides is to represent ice.

Drop The Bias - A Poem For Israel

A poem more from the Israeli side, as promised! Which one do you prefer?


Check The Facts And See - A Poem For Gaza

Just came across this video recorded at a Stop The War event I attended in London a few years ago around the time of Operation Cast Lead. Since I'm teaching about the Israel-Palestine conflict at the moment I thought this was an interesting way to present some background info - and another way to learn. Perhaps you could try writing your own poem to explain a concept or case study in geography?

Poem from the Israeli perspective to follow!

What Is Separatism?

With the recent referendum on Scottish independence and the current conflict in Ukraine, it seemed like a good time for a quick guide to what separatism is all about


What is Separatism?

Separatism is when a group of people want more political control over the area in which they live.
They want to be ‘separate’ from the rest of their country either by becoming a totally new independent country (e.g. when part of Sudan broke away to become South Sudan) or they may want to remain a part of the same country but have some of their own laws (they want more autonomy), for example, Scotland is part of the United Kingdom but some of their laws are different to the laws in England.

Should I Take Geography A-level?

Michael completed his Geography A-level 2 years ago and went on to study at University. Geogarific asked him to look back on his time at college to give us an insight into his experience, and give new students some helpful tips on how to make the most of it.

Mike and his classmates on an AS Geography field trip


Why did you decide to study Geography at A-level?
I chose to study geography as it is a good precursor to the kind of degree I wanted to do. It also provides an invaluable balance between fieldwork, independent study and essay writing.


What other subjects did you study and did they complement each other?
I studied Geology and Biology alongside Geography. Geology and Geography have an obvious cross over; this allowed me to interchange knowledge between the two subjects providing greater depth to my understanding of the physical processes that shape the Earth.

Introduction to Globalisation


Defining Globalisation

There are many definitions of globalisation as it involves many different areas including the following:

Economic – Under the auspices of GATT and latterly the WHO, world trade has expanded rapidly. TNC have been the major force in the process of increasing economic interdependence, and the emergence of different generations of NIC has been the main evidence of success in the global economy. However, the frequency of ‘anti-capitalist’ demonstrations in recent years shows that many people have grave concerns about the direction the global economy is taking. Many LEDCs and a significant number of regions within MEDCs feel excluded from the benefits of globalisation.

Urban – A hierarchy of global cities has emerged to act as the command centres of the global economy. New York, London and Tokyo are at the highest level in this hierarchy. Competition within and between the different levels of the global urban hierarchy is intensifying.

Social/Cultural – Western culture has diffused to all parts of the world through TV, cinema, the Internet etc. International interest in brand name clothes, food, music and celebrities has never been greater. However, cultural transmission is not a one-way process. The popularity of Islam has increased in many Western countries as has Asian, Latin American and African cuisine.

Linguistic – English has clearly emerged as the working language of the ‘global village’. Of the 1.9 billion English speakers, some 1.5 billion around the world speak English as a second language. In a number of countries there is great concern about the future of native languages.

Political – The power of nation states has been diminished in many parts of the world as more and more countries organise themselves in trade blocs. The EU is the most advanced model for this process of integration taking on many of the powers that were once the sole preserve of its member nation states. The UN has intervened militarily in an increasing number of countries in recent times, leading some writers to talk about the gradual movement to ‘world government’. On the other side of the coin is the growth of global terrorism.

Environmental – Increasingly, economic activity on one country has impacted on the environment in other nations. The long-range transportation of airborne pollutants is the most obvious evidence of this process. Global environmental conferences such as that in Copenhagen (2010) is evidence that most countries see the scale of the problems as so large that only coordinated international action can bring about realistic solutions.

Demographic – The movement of people across international borders and the desire to move across such borders has increased considerably in recent decades. More and more communities are becoming multicultural in nature.



Here are some definitions of globalisation:

The simple definition of globalization is the interweaving of markets, technology, information systems and telecommunications systems in a way that is shrinking the world from a size medium to a size small, and enabling each of us to reach around the world farther, faster, deeper, and cheaper than ever before, and enabling the world to reach into each of us farther, faster, deeper, cheaper than ever before. That's what globalization is” (Friedman, 2000)

Globalization is a process of interaction and integration among the people, companies, and governments of different nations, a process driven by international trade and investment and aided by information technology.
This process has effects on the environment, on culture, on political systems, on economic development and prosperity, and on human physical well-being in societies around the world.

Most definitions make reference to openness, integration or flows. Openness pertains to individual countries participating in, or being willing to participate in, international economic activity. Integration refers to combining or amalgamating elements across countries, which predominantly occurs through cross-border activity and international division of production. Flows as they pertain to globalisation encapsulates the movement of goods and services through trade, financial transaction through investment and foreign exchange markets and the sharing of ideas, intellectual property and technology.



The History of Globalisation

There is nothing new about globalisation. From ancient trade routes and the discovery and subsequent colonisation of the Americas to the invention of the transatlantic telegraph cable in 1858 there have been connections between countries around the world for centuries. Some commentators believe that ‘modern’ globalisation (a word which, by the way, has only been in common use since the late 20th century) began in the late nineteenth century when transport and communication networks expanded rapidly around the world, world trade began to grow and capital flows began to expand.


Events that have contributed to globalisation since then include:
  • The establishment of the World Bank, GATT and the Bretton Woods agreement in 1948

  • The emergence of NICs from the 1960s and the rise of TNCs

  • OPEC oil price rises in 1975, when money invested in MEDC banks was loaned to the developing world, which has cheaper labour costs

  • The integration of the Soviet Union and countries of Eastern Europe into the capitalist system in 1989 (this led to further opportunities for investment in a previously closed off market)

  • The emergence of free market ideas, promoted in the UK and USA and copied by others

  • The deregulation of world financial markets, which gave companies the freedom to expand beyond national boundaries in search of the best returns on their capital.

  •  The formation of the WTO in 1995 and other trade blocs.

  • Advances in technology and communications e.g. the internet (1980s), mobile phones, jumbo jets, fibre optic cables and satellites allowed cheaper and quicker transport of information, goods and people.

  • Although labour markets are not as advanced as financial markets (due to the difficult of moving people compared to money and the affinity people feel to their home country) there has been increasing movement of people across borders seeking employment. Much of this has been from lower to higher income countries, e.g. from South to North America and East to West Europe.



Global Marketing

Global marketing has been defined as ‘marketing on a worldwide scale, taking commercial advantage of global operational differences similarities and opportunities in order to meet global objectives’.

When a company becomes a global marketer it views the world as one market and creates products that fit various regional marketplaces. The ultimate goal is to sell the same thing, the same way, everywhere.

Coca-Cola is an example of a company with a single product. Only minor elements are tweaked for different markets. They use the same formulas (one with sugar, the other with corn syrup) for all its markets. The design of the bottle/can is the same in every country but the size varies according to country standards. Some people are concerned that this type of marketing will erode local diversity.



The New International Division of Labour

Globalisation has brought about a new division of labour on a global scale. The highly skilled, highly paid, decision making, research and managerial occupations tend to be located in high-income, developed countries, whereas the unskilled, poorly pair assembly jobs can be found in developing countries.

This simple division has undergone radical changes since the 1960s. Countries have moved from developing, to NICs, to MEDCs in the space of 40 years, while others have also started industrialising and are at various stages of being NICs or RICs. This has had a huge impact on the location of different types of jobs.



Global Shift

Global shift is the movement of economic activity from MEDCs, originally to NICs, then to RICs and LECDs. Initially the shift involved labour-intensive manufacturing, but increasingly it has involved all sorts of manufacturing and, more recently, services.

Manufacturing
In the 1950s around 95% of manufacturing was concentrated in the industrial economies. As large companies grew in these areas they began to look for ways to reduce their costs. At the same time improving communications and transport enabled them to search the world for cheaper manufacturing locations. FDI in NICs such as Singapore led to deindustrialisation in MEDCs. Later there were shift from NICs to RICs to keep costs low, and as NICs developed they set up their own industries, investing in countries less developed than themselves.

This shift has been aided by the transfer of technology. High levels of technology are no longer associated with high productivity and high wages. Companies in the developing world are now able to increase their productivity through technology without raising their wages. This could widen the development gap, as workers in the developing world are paid less to make the same products as those in developed countries. By the beginning of the 21st century, more than 50% of all manufacturing jobs were located in the developing world and over 0% of exports from those countries to the developed world were of manufactured goods.

Services
There has also been a shift in services as they have become increasingly detached from the manufacturing sector. As manufacturing has dispersed worldwide, the top of the service hierarchy become concentrated in cities such as London, New York and Tokyo rather than in old manufacturing centres. Low level services on the o0ther hand have shifted to the developing world much like manufacturing. Call-centre operations, for example, have moved from the UK to India where employment costs are generally 10 – 20% of those in the UK.

What is a Tsunami?

Here is a summary of the key points you need to know about tsunamis for GEOG3, check out the video below which is some raw footage of the Japan tsunami to give you an idea of the time scale and destruction involved. It's hard to imagine how long the waves are actually moving inland for, scary!



• A tsunami is a series of waves, called a wave train, which can be up to 100km long and 1 hour apart.

• These waves can reach heights of 30meters, although most of them are no more than 3 meters


• About 80% of tsunamis happen within the “Ring of Fire”. They are usually caused by underwater earthquakes when the ocean floor rises at a plate boundary and displaces the water above it.


• They have also been know to be caused by underwater landslides, volcanic eruptions or meteorites impacts.


• They race across the sea at up to 500 miles an hour and can cross the entire Pacific Ocean in less than a day while their long wavelengths mean they lose very little energy along the way.


• In deep ocean, tsunami waves may appear only a foot  high but as they approach the shore shallow water slows them down and the tops of the waves move faster than the bottoms so they grow in energy and height.


• A tsunami’s trough, the low point beneath the crest, often reaches shore first, producing a vacuum effect that sucks coastal water seaward exposing harbours and sea floors.


• Flooding can extend 10 miles inland, lifting giant boulders, flipping vehicles and demolishing houses.

Advanced Earthquake Engineering and Preparation in Japan


Japan is a nation that has grown rapidly in the last few decades, both economically and socially. During its development Japan invested well in technology and is now one of the biggest technology exporting countries in the world today. Moreover it has managed to achieve this despite being in an area of the world that is riddled with environmental hazards. 

One of the most hazardous is the threat of a major earthquake. Tokyo, is one of the three most densely populated cities on the planet where seismologists expect major earthquakes to occur. However it is one of the few places on the planet where such seismic activity doesn’t usually cause catastrophic damage. Why is this? It is because of the adaptation techniques that Japan have installed.


Adaptation is the process by which a country prepares itself for the inevitable hazard, in this case earthquakes and their side effects. One way in which Japan has done this is by changing the way in which modern buildings are designed. It is possible these days the design buildings to sustain the effects of the ground shaking caused by earthquakes because we now know far more about how buildings behave in different scenarios.  

One way in which buildings are being designed to sustain the effects of an earthquake is by putting in dampeners. This is far cheaper to do than using building techniques that make the structure far stronger. A dampener is a mechanism that absorbs the energy of the vibrations caused by the quake and makes the movement die away over time. 

One type of dampener is  called a tuned mass damper (TMD). This involves installing a huge mass, either mounted on springs or as a pendulum, which is tuned to have a natural frequency close to that of the building. In the event of an earthquake at close to that resonant frequency, the TMD oscillates in the opposite direction to the building, counteracting its motion. 

The natural frequency of the building can be calculated by using the formula:


where K is the stiffness constant of the building and M is the mass of the building.  Structures can be both reinforced horizontally and vertically, by using: diaphragms, trussing, braced frames, shear walls and moment resisting frames.

However structural reinforcing and engineering is not the only way in which Japan is reducing the damaged caused by earthquakes. They have installed my pre-earthquake warning systems such as sirens that allow people such as school children to prepare for the imminent tremors by doing things such as hiding under desks or gathering in areas that should be safest from falling debris and collapsing buildings. 

Another way in which Japan try and prevent catastrophes during earthquakes is by shutting down core reactors in nuclear power plants to avoid meltdowns and radiation related disasters. 

The way in which Japan is now prepared for the threat of earthquakes has not always been the case and much of the planning and building regulations for “earthquake safe” buildings only came in after the Kobe earthquake in 1995. During which over 6,400 people lost their lives and thousands of homes were destroyed.
