Question 642Navigation General70% to pass
Variation is not constant; it is different with every change in _______________.
AI Explanation
The correct answer is B) geographical location.
Magnetic variation, which is the difference between true north and magnetic north, changes based on the vessel's geographical location. This is because the Earth's magnetic field is not uniform, and it varies across different regions. As a vessel moves to different locations, the magnetic variation it experiences will change accordingly. The other options (vessel heading, speed, and cargo) do not directly affect the magnetic variation a vessel experiences.
