These 9 little gems (Spatial Concepts) will so help us kick some Geography butt this year. Let’s start slow.......
Geography is the study of the earth and the way that things are arranged across the earth.
We use our geographic skills constantly-the main skill being the art of observation. You would be surprised at just how much information can be unlocked from a simple form of geographic data such as a photograph.
Geographers identify and investigate any patterns that may emerge in the way that things are distributed.
Observe the composite satellite photograph of the world at night
What are spatial concepts?
Uuh what does spatial mean?
THIS IS NOT REFERRING TO THE SPACEMEN AND ALIENS SPACE!
This sign shows you the location of the Murry Darling Basin
Location depends upon distance and direction.
These signs details distance to landmarks.
Distance is just the space between two or more locations.
Determining distance on a map requires that you have a knowledge of scale. Most of you would have used map scale in junior levels to determine distances.
You can also think of distance as being the time or cost of moving between locations. This concept is known as relative distance.
e.g. I catch the Werribee train every morning to get to school from Southern Cross Station. The TIME it takes affects my relative distance. (I also have to pay which influences the relative distance, grrrr!)
This refers to the size of a feature in relation to another feature. You are now familiar with map scale- how much the map needed to be reduced in size to fit on the paper you can see in front of you.
Scale allows you to express distance in kms.
BUT WAIT, there is more!!!
Scale can also be used by geographers to describe the SIZE of the area being studied.
When you study the Docklands you will be investigating a small region. This is known as Local scale.
If we were to study a larger area such as the Mallee or the Wimmera then we would be investigating at the Regional scale.
A study of Australia would be at the National scale.
A study of the spread of AIDS could be best achieved at a Global scale.
Distribution refers to the way features are arranged over space. The features may in fact form patterns or be grouped together.
The location of Trans-Siberian towns in Russia are a great example of a LINEAR pattern.
We would say that towns along the railway are distributed in a linear pattern.
The key with distribution is being able to first identify any patterns and then suggest reasons why the patterns may exist.
Describe the distribution of Greek born migrants across Melbourne. Are there any patterns? Are there any clusters? Do they form a pattern similar to those displayed at the top of page 8 of the textbook?
Suggest a reason to explain this pattern.
Wetlands are a natural region
A region is an area of the earth’s surface that contain one or more characteristics that distinguish it from other areas.
Change is inevitable.
Areas change their geographic characteristics over time.
Think of Melbourne’s newest suburbs to the west, like Caroline Springs. These were once cow paddocks!
Geographers need to be able to identify and account for these changes.
This is one of the most important of the KGIs.
Spatial Association describes a situation where two or more features have a similar pattern of distribution.
Rainforests and areas of high rainfall have a strong spatial association so to do areas which receive less than 250mm of rain per year and the location of deserts.
You can use three terms to describe the extent of spatial association, strong, weak or non-existent.
Spatial Association is just a statement about how similar the patterns are.
Observe the map of India on page 11 of the textbook.
How would you describe spatial association between female literacy rates and infant mortality levels?
Suggest a reason why this level of association may exist?
Water flows in the Moorabool River.
Energy can also be moved. One of your studies this year will examine erosion along a beach. This involves the movement of energy leading to the movement of rock material.
Maps often show movement with arrows.
Proportional flow lines can be used to show the ‘extent’ of the movement ( thinner arrows and fatter arrows)
Complete activities 1 and 2 on page 10 of the textbook.
Good examples of spatial interaction include the Gold Coast and Schoolies, drought forcing farmers off the land, the depletion of the Amazon rainforest, pollution in the Yarra and the disappearance of aquatic life.
