Maps

Question 1

Proportional map

Answer 1

proportional maps are a type of thematic map.
They show data using symbols (usually circles), and the size of the symbol is proportional to the value being represented.
So in your example:
If the theme is population or diversity,
Toronto would have a larger circle because it has a larger value,
Alberta (or a smaller city/area) would have a smaller circle.
One small correction though:
Proportional maps don’t automatically mean “diversity” — they can show any numerical data (population, number of immigrants, income, disease cases, etc.).
The circle size shows how much, not why.
If you want a clean, school-ready version, you could say:
A proportional map is a type of thematic map that uses symbols, such as circles, to represent data. The size of each symbol shows the amount of the variable being measured. For example, a city like Toronto would have a larger circle than other areas because it has a larger population or higher diversity.

Question 2

What is significant about a proportion map

Answer 2

A proportional map does NOT show individual things one by one.
Instead, it shows a total amount for an area using one big symbol (like a circle).
So:
The circle does NOT equal one McDonald’s
The circle represents the total number of McDonald’s in that area
Bigger circle = more
Smaller circle = less
For example:
Toronto → one large circle showing the total number of McDonald’s in Toronto
A smaller city → one small circle showing fewer McDonald’s
You could explain it like this:
A proportional map uses one symbol per area, and the size of the symbol represents the total amount of a certain variable, not individual locations.

Question 3

Flowline maps

Answer 3

A flow-line map is a type of thematic map that shows movement from one place to another.
Key ideas:
Lines or arrows show movement
The direction shows where things are going
The thickness of the line shows how many or how much
Examples:
Migration of people from one region/country to another
Trade routes, like ships moving food or goods
Movement of resources (oil, grain, water)
So your examples work perfectly:
Migrants moving from one area to another 🧍‍♀️➡️🧍‍♂️
Ships transporting food 🚢
A clean, school-style sentence you could use:
A flow-line map is a thematic map that shows movement between places, such as migration or the transportation of goods, using lines or arrows.

Question 4

Isoline map

Answer 4

An isoline map emphasizes boundaries between areas that have different values.
Just like your example:
Milk on one side 🥛
Water on the other 💧
You need a clear boundary so you know where one stops and the other starts
On an isoline map:
One side of the line has one value
The other side has a different value
The line shows where the change happens
Examples:
Time zone boundary → different times
Temperature line → warmer vs cooler areas
Elevation contour → higher vs lower land
A really strong, simple way to say it:
Isoline maps use boundaries (lines) to clearly show where values change from one area to another.

Question 5

Couropleth map

Answer 5

Choropleth map
Thematic map that uses shading or colour to show data
Darker colour = more of something
Lighter colour = less of something, but it’s still there
Entire areas are coloured, not individual points
Good for things like population, income, rainfall, election results
So in your “water painting” analogy:
Dark purple on a province → lots of the thing (like lots of rainfall)
Light purple → just a little of it
White or very light → almost none
💡 Quick way to remember:
Choropleth = colour the areas
Proportional = symbol for the area
Isoline = lines showing change
Flow-line = arrows showing movement
If you want, I can make a tiny visual cheat sheet comparing all four map types so it’s easy to see the difference at a glance. It’d be really helpful for tests. Do you want me to do that?
