On an isomagnetic chart, the line of zero variation is the _______________.
AI Explanation
The correct answer is A) agonic line.
On an isomagnetic chart, the agonic line represents the line of zero magnetic variation, where the true north and magnetic north are aligned. This means that the angle between true north and magnetic north is zero degrees along the agonic line. The agonic line is the line of zero variation on an isomagnetic chart.
The other options are incorrect because:
B) isogonic line represents lines of equal magnetic variation, not zero variation.
C) variation line is a general term that does not specifically refer to the line of zero variation.
D) zero variation line is not a standard term used in navigation.
