At a point A on the earth's surface the angle of dip, δ = +25^°. At a point B on the earth's surface the angle of dip, δ = -25^°. We can interpret that :
1. A and B are both located in the northern hemisphere.
2. A is located in the southern hemisphere and B is located in the northern hemisphere.
3. A is located in the northern hemisphere and B is located in the southern hemisphere.
4. A and B are both located in the southern hemisphere.
