⚠️ Top Mistakes to Avoid on This Topic
- Confusing latitude and longitude: Latitude lines run east–west but measure north–south distance. Longitude lines run north–south but measure east–west distance.
- Forgetting units on scale questions: Always include the unit (miles, km) in your answer.
- Mixing up physical and political maps: Physical = natural features. Political = human-made boundaries.
- Forgetting TODALS elements: Students often forget Date and Author. Remember the full acronym!
Question 1 Easy
Name the 6 elements every map should have (TODALS) and explain what the legend shows.
1
T — Title: Tells what the map is about (e.g., “Political Map of Europe”).
2
O — Orientation: A compass rose or north arrow showing which direction is north.
3
D — Date: When the map was created or last updated.
4
A — Author: Who created the map (person, organisation, or agency).
5
L — Legend (Key): Explains the symbols, colours, and patterns used on the map. For example, a blue line might represent a river, or a star might represent a capital city.
6
S — Scale: Shows the ratio between distance on the map and distance in real life (e.g., 1 inch = 100 miles).
TODALS: Title, Orientation, Date, Author, Legend, Scale. The legend explains what symbols on the map represent.
Question 2 Easy
Map scale: 1 inch = 200 miles, cities are 4.5 inches apart.
1
Identify the scale: 1 inch on the map = 200 miles in real life.
2
Measure the map distance: 4.5 inches apart.
3
Multiply: 4.5 inches × 200 miles/inch = 900 miles.
The two cities are 900 miles apart in real life.
Question 3 Easy
Difference between a physical map and a political map.
1
Physical map: Shows natural features of the Earth’s surface — mountains, rivers, deserts, lakes, oceans, and elevation. Example: A physical map of Asia would show the Himalayan Mountains, the Gobi Desert, and the Ganges River.
2
Political map: Shows human-made boundaries — country borders, state/province lines, capital cities, and major cities. Example: A political map of Europe would show country borders, capital cities like Paris and Berlin, and the names of countries.
Physical = natural features (mountains, rivers). Political = human boundaries (countries, capitals).
Question 4 Medium
Difference between latitude and longitude.
1
Latitude: Measures distance north or south of the Equator (0°). Ranges from 0° to 90°N or 90°S. Lines of latitude run east–west (horizontally) but measure north–south position.
2
Longitude: Measures distance east or west of the Prime Meridian (0°). Ranges from 0° to 180°E or 180°W. Lines of longitude run north–south (vertically) but measure east–west position.
3
Key reference lines: Latitude → Equator (0°). Longitude → Prime Meridian (0°, through Greenwich, England).
4
Memory trick: Latitude = “ladder” (horizontal rungs). Longitude = “long” (vertical lines running the “long” way from pole to pole).
Latitude: east–west lines, measures N/S (Equator = 0°). Longitude: north–south lines, measures E/W (Prime Meridian = 0°).
Question 5 Medium
Location at 35°N, 139°E — identify country and hemispheres.
1
a) Country/city: 35°N, 139°E is the approximate location of Tokyo, Japan.
2
b) N/S Hemisphere: 35°N means it is in the Northern Hemisphere (north of the Equator).
3
c) E/W Hemisphere: 139°E means it is in the Eastern Hemisphere (east of the Prime Meridian).
a) Tokyo, Japan. b) Northern Hemisphere. c) Eastern Hemisphere.
Question 6 Medium
What is a thematic map? Name two types.
1
Definition: A thematic map focuses on a specific topic or theme, rather than showing general geography. It uses colours, symbols, or patterns to display data about that theme.
2
Type 1 — Choropleth map: Uses shading or colour gradients to show data values across regions. Example: A map shading countries by population density (darker = more dense).
3
Type 2 — Dot density map: Uses dots to show the distribution of a feature. Each dot represents a certain number of items. Example: A map with dots representing 10,000 people each, showing population distribution.
A thematic map shows specific data. Examples: choropleth (shaded regions by data value) and dot density (dots representing quantities).
Question 7 Medium
How is GIS different from a paper map? Give one advantage.
1
GIS (Geographic Information Systems) is a computer-based system that captures, stores, analyses, and displays geographic data. It combines multiple layers of information (e.g., roads, elevation, population, weather) in one interactive system.
2
Paper map: A static, printed representation of geographic information. It shows one set of data and cannot be updated or interacted with.
3
Key difference: GIS is digital, interactive, and can layer multiple datasets. A paper map is static and shows only one type of information at a time.
4
Advantage of GIS: GIS can overlay multiple layers of data (e.g., showing earthquake zones, population centres, and hospital locations on one map) to help with decision-making, disaster planning, and analysis. It can also be updated in real time.
GIS is digital and interactive with multiple data layers; paper maps are static. Advantage: GIS can layer and analyse multiple datasets for better decision-making.
Question 8 Hard
Compare topographic and choropleth maps.
1
Topographic map: Shows the shape and elevation of the land surface using contour lines (lines connecting points of equal elevation). Data: physical elevation, slope, terrain features. Use case: Hikers, engineers, and military planners use topographic maps to understand terrain.
2
Choropleth map: Uses colour shading to show statistical data across defined regions (countries, states, counties). Data: any quantitative data such as population density, income levels, literacy rates. Use case: Geographers and policymakers use choropleth maps to compare data across regions.
3
Key comparison: Topographic maps show physical terrain (elevation). Choropleth maps show human/statistical data (demographics, economics). A geographer would use a topographic map to plan a hiking trail and a choropleth map to compare literacy rates across African countries.
Topographic = elevation via contour lines (terrain). Choropleth = statistical data via colour shading (demographics). Different purposes: terrain analysis vs. data comparison.
Question 9 Hard
Why is the Prime Meridian at Greenwich? What does the International Date Line do?
1
a) Why Greenwich? In 1884, delegates from 25 countries met at the International Meridian Conference in Washington, D.C., and agreed to place the Prime Meridian (0° longitude) through the Royal Observatory in Greenwich, England. This was chosen because: Britain was the world’s leading naval and colonial power at the time; most of the world’s shipping charts already used Greenwich as the reference point; and the Royal Observatory had precise astronomical instruments for measuring time and position.
2
b) International Date Line: The International Date Line (IDL) is an imaginary line located at roughly 180° longitude in the Pacific Ocean. When you cross the IDL going westward, you move forward one calendar day (e.g., Monday becomes Tuesday). When you cross it going eastward, you move back one day. It exists because the Earth rotates, and without a date-change boundary, circumnavigating the globe would cause date confusion.
a) Greenwich chosen in 1884 because Britain led global navigation and most charts already used it. b) The International Date Line (at ~180° longitude) is where the calendar date changes by one day.
Question 10 Hard
Map where countries are sized by population, not land area. What type? How does it distort?
1
a) Map type: This is called a cartogram. In a cartogram, the size of each country is distorted to represent a specific variable (in this case, population) rather than actual geographic area.
2
b) Distortion: A population cartogram can distort a reader’s understanding by making densely populated countries look enormous and sparsely populated countries look tiny. This may lead readers to underestimate the physical size and geographic importance of large, sparsely populated countries.
3
c) Specific example: Canada is the world’s 2nd largest country by land area (9.98 million km²) but has only ~38 million people. On a population cartogram, Canada would appear tiny. Meanwhile, Bangladesh (only 148,000 km²) has over 170 million people and would appear much larger than Canada. Another example: India and China would dominate the map, while Russia (the world’s largest country by area) would appear relatively small.
a) Cartogram. b) It distorts physical size — large but sparse countries shrink, small but dense countries grow. c) Canada (huge area, small pop) would look tiny; Bangladesh (small area, huge pop) would look large.

I do not understand the difference between a choropleth map and a cartogram. Can you give me three simple real-world examples of each and explain when a geographer would choose one over the other?
