Question 673Navigation General

The correct answer is A) dip. The dip, also known as the magnetic inclination, is the vertical angle between the horizontal plane and the magnetic line of force at a given location on the Earth's surface. This angle is a result of the Earth's magnetic field and varies depending on the geographical location. The other options are incorrect because: B) Elevation refers to the height above a reference level, which is not the same as the dip angle. C) Vertical angle is a more general term that does not specifically refer to the angle between the horizontal and the magnetic line of force. D) Magnetic angle is not a commonly used term in this context.
