Geography assessment study

Maps and Their Types

●​ Political maps: Show boundaries of countries, states, and cities.


●​ Topographic maps: Display elevation and terrain using contour lines.
●​ Cartograms: Represent data using distorted maps to emphasize statistics (e.g.,
population density).

Map Skills

Direction

●​ Use a compass to determine North, South, East, and West.


●​ Intercardinal directions include NE, NW, SE, SW.
●​ Example: If a map shows a landmark northwest of your location, move
diagonally between north and west.

Scale & Distance

●​ Maps have a scale (e.g., 1:50,000 means 1 cm = 500 m in real life).


●​ To measure distance:
1.​ Use a ruler to measure between two points.
2.​ Multiply by the scale to get the real-world distance.
3.​ For curved paths, use a piece of string to follow the route, then
measure the string.

Grid References

●​ Maps have grid lines labeled with numbers.


●​ 4-figure grid references locate a general area (e.g., 4733).
●​ 6-figure grid references pinpoint exact locations (e.g., 476334).
●​ Example: To find a location, move east first (along the corridor), then north
(up the stairs) BBC Guide.

Latitude & Longitude

●​ Latitude lines run horizontally (North-South).


●​ Longitude lines run vertically (East-West).
●​ Example: Sydney is at 33.87°S, 151.21°E.

Bearings

●​ Bearings are measured clockwise from north using a protractor.


●​ Example: If a landmark is east, its bearing is 90°.

Aspect

●​ Aspect refers to the direction a slope faces.


●​ Example: A south-facing slope gets less sunlight than a north-facing slope.

Density

●​ Density measures how crowded something is.


●​ Example: Population density = Number of people ÷ Area.

Gradient

●​ Gradient = Vertical height ÷ Horizontal distance.


●​ Example: If a hill rises 100m over 500m, its gradient is 1:5.

Altitude

●​ Altitude is measured in meters above sea level.


●​ Example: Mount Everest’s altitude is 8,848m.

Geographical Data Interpretation

●​ Synoptic charts: Used in weather forecasting, showing air pressure, wind speed,
and fronts.
●​ Local relief: Difference in elevation between the highest and lowest points of a
landscape.
●​ Area: The total space a place or region covers.
●​ Population pyramids: Graphs that illustrate age and gender distribution in a
population.
●​ Data tables & graphs: Organize numerical information for analysis.
●​ Statistics: Used to find trends, patterns, and explain geographical changes.
