Choose the correct answer
A
Angle between true north and magnetic north at a given location and time
B
Dip of compass needle
C
Error in compass reading
D
Difference between two bearings
Correct Answer
A. Angle between true north and magnetic north at a given location and time
Why is this the answer?
Magnetic declination (variation): horizontal angle between true (geographic) north and magnetic north. Changes with location and time. West declination: magnetic north west of true north → add to magnetic bearing for true bearing (if west).
