Spatial Concepts - **Spatial Concepts.pptx**

You must understand the 9 spatial concepts and be able to apply them when answering questions. You will be expected to be able to use them comfortably when responding to questions during this course.

Use the sentence starters on page 12 of the textbook to help you in creating appropriate statements. PRACTISE.

There will be more work on various spatial concepts throughout the course, but if this is your first year of Geography then you should definitely be doing extra practise.

Mapping

Map skills are important in Geography and will be needed for your exam, especially map reading skills. You need to be able to satisfy mapping conventions, and the easiest way to do this is to use BOLTSS, use pencils, rulers, be neat and be ACCURATE!

1. Create an overlay of rainfall distribution in the MDB. This is done on transparent paper and must also include BOLTSS. Use the Rainfall Distribution map on p.4 of the supplement.
2. Stick the top edge of the overlay map onto the base map in your book. **MDB base map.doc**

Distribution

Before we describe Spatial Association lets practise plain old distribution.
1. Describe the distribution of Ramsar Convention wetlands in the MDB using the map in New Perspectives p.

Use: Pattern Example Exception Quantification

This acronym will help you create a solid answer. You must ALWAYS give an example with information from the source maps, BE SPECIFIC, e.g. an average of 300 mm/year of rainfall.

The average annual rainfall in the MDB has a linear pattern.
For example, the east of the MDB receives on average more than 600 mm/year of rain in areas such as Narrabri and Tamworth (800+mm/year), and decreases towards the west where some areas such as Broken Hill and Morgan receive less than 300mm/year.
However, the south of the MDB, along the Great Dividing Range there is still high average annual rainfall despite being further west, e.g. Seymour has over 600mm/year.

Use these worksheets to practise, and I will gladly mark them for you. Distribution worksheets.docx


Describing Spatial Association

Use: Degree Example Exception Quantification

First state what the spatial association is (the degree). Is it strong/moderate/weak

When giving an example, be sure to use figures/names from BOTH maps.

1. Describe the relationship between population centres in the MDB and rainfall distribution.

First you need to identify, where are most of the towns? Then, are they mostly located in one area of rainfall?

YES, most towns are where there is more rainfall. There is a STRONG relationship.

Now, choose two towns as your examples and state how much rainfall they receive on average/year.

What about the other towns that are located in areas of low rainfall? They are the exceptions. Again, name two towns and their average rainfall/year stating that they are the exception.

There is a strong relationship between rainfall and population centres in the MDB.
For example, the majority of towns are located where there is more than 600mm of rainfall per year, such as Tamworth (600mm/year) and Toowomba (800mm/year).
However, there are population centres located in areas of low average rainfall such as Broken Hill and White Cliff which both receive less than 300mm/year of rainfall.
