MCQ
Isogonic lines on magnetic map will have
  • A
    Zero angle of dip
  • B
    Zero angle of declination
  • Same angle of declination
  • D
    Same angle of dip

Answer

Correct option: C.
Same angle of declination
c
(c) Isogonal lines on a magnetic map will have same angle of magnetic declination. Magnetic declination is the angle on the horizontal plane between magnetic north and true north. This angle varies depending on position on the earth's surface, and changes over time.
