Which of the following statements are true for Magnetic Declination? i. It is the horizontal angle between the True Meridian and Magnetic Meridian at a place ii. It is the vertical angle between the True Meridian and Magnetic Meridian at a place iii. The declination can be towards East or West iv. The declination can be towards North or South
- A(i) and (iii)Correct
- B(ii) and (iii)
- C(i) and (iv)
- D(ii) and (iv)
Solution
Concept
Declination
Step-by-step solution
1. Declination is the horizontal angle between the true meridian and the magnetic meridian. 2. It is east or west, depending on which side of true north the magnetic north lies.
Explanation
The vertical angle is the dip, not the declination.
Why the other options are wrong
Options with (ii) or (iv) are wrong.
Shortcut
Declination: horizontal, E/W. Dip: vertical.
Common mistake
Mixing declination with dip.
Correct answer: A) (i) and (iii)
