Question: To orient a map using a compass and true north, what correction factor should be applied in most Canadian locations?
Answer options: ✅ A declination adjustment (magnetic north vs. true north)
- An altitude adjustment for mountainous terrain
- A time zone adjustment
- A grid convergence correction for all maps
Correct answer: A declination adjustment (magnetic north vs. true north)
Explanation: Magnetic declination is the angle between magnetic north (where a compass points) and true north (geographic north pole). This adjustment is essential in Canada as declination varies significantly across the country and must be accounted for to accurately orient a map with a compass.
