Mapping Skills practise test Flashcards
What are the four cardinal directions?
North, East, South, West
What does a scale of 1:50,000 mean?
1 cm on the map represents 50,000 cm (or 500 meters) in real life.
What is the difference between a topographic map and a thematic map?
A topographic map shows physical features and elevation, while a thematic map focuses on a specific theme, such as population density or climate.
What does the contour interval on a topographic map indicate?
The contour interval represents the difference in elevation between adjacent contour lines.
How can you identify a steep slope on a topographic map?
Contour lines that are close together indicate a steep slope, while widely spaced lines indicate a gentle slope.
What is the difference between a four-figure and a six-figure grid reference?
A four-figure grid reference (e.g., 2456) gives the general location within a square on a grid.
A six-figure grid reference (e.g., 245567) provides a more precise location within that square.
Find the four-figure grid reference for a point located at (24, 56) on the map.
2456
If a landmark is located at grid reference 387453, what type of reference is this?
Six-figure grid reference.
Using a scale of 1:100,000, how many kilometres does 5 cm on the map represent?
5 cm × 1,000 m = 5 km
If a road is 12 km in real life, how long would it be on a map with a 1:50,000 scale?
12,000 ÷ 50,000 = 0.24 meters (24 cm) on the map.
How do you identify a river valley on a topographic map?
A river valley is represented by contour lines forming a V-shape pointing upstream (towards higher elevation).
What type of landform is indicated by closed contour lines with decreasing elevation values?
A depression or basin.
If contour lines form a circular pattern with increasing elevation toward the centre, what does it represent?
A hill or mountain.
What is the bearing from point A (grid reference 302405) to point B (grid reference 312410)?
Use a protractor to measure the clockwise angle from the north. The answer varies based on the map used.
What is the latitude and longitude of the Equator and the Prime Meridian?
The Equator is 0° latitude, and the Prime Meridian is 0° longitude.
If a location is at 30°N, 45°E, which hemisphere(s) is it located?
Northern Hemisphere and Eastern Hemisphere.
How can contour lines be used to identify a plateau?
A plateau appears as a series of closely spaced contour lines indicating a steep slope, followed by widely spaced or nearly flat contour lines at the top.
Why do topographic maps use different colours for elevation?
Different colours help distinguish elevation changes—green for lowlands, yellow for higher elevations, and brown for mountains.
If a map shows a scale of 1:25,000, and the real-world distance between two towns is 10 km, how long is the distance on the map?
10,000 m ÷ 25,000 = 0.4 m (or 40 cm on the map).
