Question 446Navigation General70% to pass
Lines on a chart which connect points of equal magnetic variation are called _______________.
AI Explanation
The correct answer is B) isogonic lines.
Isogonic lines, also known as isogons, are lines on a chart that connect points of equal magnetic variation, which is the difference between true north and magnetic north. These lines are used to determine the magnetic compass direction on a chart, which is important for navigation.
The other answer choices are incorrect because:
A) Magnetic declination refers to the angle between true north and magnetic north, not the lines connecting points of equal declination.
C) Magnetic latitudes refer to the lines of equal magnetic intensity, not lines of equal magnetic variation.
D) Dip refers to the angle between the horizontal and the direction of the earth's magnetic field, not the lines connecting points of equal variation.
