Which of the following statements is CORRECT about the earth's magnetic field?
Answer Details
The Earth has a magnetic field that acts like a giant bar magnet with its magnetic field lines directed from the geographic North Pole to the geographic South Pole. The magnetic field of the earth is responsible for the phenomenon of magnetism, and it has three important elements: the angle of dip, the angle of declination, and the angle of inclination.
The angle of dip is the angle that a freely suspended magnet makes with the horizontal plane. The angle of dip is also known as the angle of inclination.
The angle of declination is the angle between the magnetic meridian and the geographic meridian. It is the angle that a magnetic compass makes with the geographic meridian. The magnetic meridian is the imaginary line that passes through the geographic North Pole and the south magnetic pole.
Therefore, the correct statement is "the angle of declination is the angle between the magnetic meridian and the geographic meridian."
