Geography Skills 03

Choropleth maps turn data into colour, helping geographers see patterns such as crowded cities, quiet countryside and places with high or low rainfall at a quick glance.

Fascinating Fact:

A choropleth map uses different shades or colours to show how a value, such as population density, changes from one area to another.

In KS3 Geography, you learn how to choose the best way to display data on maps and graphs. Choropleth maps use shading to compare how values change between different areas, helping you spot patterns quickly.

  • Choropleth map: A thematic map that shades whole areas to show how a single value, such as population density, changes from place to place.
  • Population density: The number of people living in a given area, usually measured as people per square kilometre.
  • Legend (key): The part of a map that explains what the symbols or shades mean so you can read the data correctly.
What is a choropleth map in KS3 Geography?

A choropleth map is a type of thematic map that uses different shades of one colour to show how a value, such as income or rainfall, varies between areas.

When should I use a choropleth map instead of a graph?

You should use a choropleth map when your data is linked to areas, such as countries or regions, and you want to show spatial patterns rather than exact numbers for each place.

How do you read a choropleth map step by step?

First read the title to see what is being shown, then check the legend to understand what the shades mean, and finally compare the darkest and lightest areas to spot patterns.

1 .
What is often at the end of a line on a flow map?
Arrow head
Asterisk
Cross
Circle
The arrow head shows the direction of flow
2 .
Maps using lines of different widths to show the value of data are called what?
Expanding maps
Flatline maps
Flow line maps
Linear maps
Useful for showing movements of goods, people and information
3 .
What does the line on a climate graph show?
Hours of sunshine
Rainfall
Temperature
Wind speed
The bars on a climate graph show rainfall
4 .
Which of the following would be the most appropriate way to show the link between changes in river velocity and rainfall?
Bar graph
Choropleth map
Scatter graph
Pie chart
Scatter graphs help to identify relationships (links) between data sets
5 .
When would it be very difficult or even impossible to draw a line of best fit?
When there are less than ten points plotted
When there is a negative relationship
When there is a positive relationship
When there is no link between the data
The values will be scattered in no definite pattern
6 .
On a scatter graph, if one value increases while the other decreases, it shows what?
A negative relationship
A positive relationship
No relationship
You have drawn it wrong
When both increase at the same time it's a positive relationship
7 .
Which creature gives its name to a type of diagram?
Butterfly
Centipede
Octopus
Spider
You must have drawn loads of these! They are a great way of organising your thoughts or summarising information
8 .
The link between number of doctors and life expectancy should be shown on what?
A block bar graph
A divided bar graph
A population pyramid
A scatter graph
You can then draw a line of best fit to spot any pattern
9 .
Which map should be used to show air pressure?
Atlas
Choropleth
Flow line
Isoline
Isolines showing areas with the same air pressure are called isobars
10 .
What is the best choice of map to show ocean currents?
Flow line map
Isoline map
Ordnance Survey map
Sketch map
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
