Question

Why do the declination is greater in higher latitudes than in equators?

Answer 1

It is because of the shape of the magnetic field of the earth.

Explanation:

• The lines of the field close tot he magnetic poles come out abruptly by the side of the axis of the Earth, by the protocol at the South magnetic pole, at a comparatively vertical angle to the polar edges, and curve round to enter again at the north magnetic pole.
• Halfway lines appear between the surface of the Earth, having previously transformed the direction aside from the axis, and meet the edge of the Earth at a smaller vertical angle.

Answer 2

The declination is greater in higher latitudes than in equators because:

• There is a variation in angle between the magnetic meridian and geographic meridian at both places.

• The angle of declination can be defined as the angle between the geographical meridian and the magnetic meridian.

• Towards the equator, the magnetic meridian is close to the geographic meridian and due to which the angle is small. This results in small declination.

• Towards higher latitudes, both the meridians are far apart and thus the angle is large. This results in large declination.
