Test your geography skills in this KS3 quiz. Geography is mostly about data handling in one form or another. OS maps contain data that shows the location of geographical features like woods, valleys and buildings. A relief map shows data about the heights above and below mean sea level. The data on a weather map shows air pressure, temperature, wind speed and other related atmospheric phenomena. Different maps are therefore used for different purposes, depending on what data is to be shown.
Sometimes it is difficult to show some data using a map, so we use a chart instead. A good example of this is showing the climate for a particular place. When time is involved, maps are not very good at showing it. You need a different map for different times, so things can get quite bulky. To show the climate for a location requires data that covers a 12 month period, so you would need 12 maps. But then there is the problem of showing temperature and rainfall on the same map. The solution is to use a climate chart instead. The rainfall is shown using bars, like on a bar chart and the temperature is drawn as a line.

You can then draw a line of best fit to spot any pattern

You must have drawn loads of these! They are a great way of organising your thoughts or summarising information
|
When both increase at the same time it's a positive relationship

Scatter graphs help to identify relationships (links) between data sets

The values will be scattered in no definite pattern

Isolines showing areas with the same air pressure are called isobars

The bars on a climate graph show rainfall

The arrow head shows the direction of flow

You can use different colours to show which are warm currents and which are cold currents. Thicker and thinner arrows could be used to show stronger and weaker currents
