At a point A on the earth's surface the angle of dip, \( \delta = +25^\circ \). At a point B on the earth's surface the angle of dip, \( \delta = -25^\circ \). We can interpret that:

1. A is located in the northern hemisphere and B is located in the southern hemisphere.
2. A and B are both located in the southern hemisphere.
3. A and B are both located in the northern hemisphere.
4. A is located in the southern hemisphere and B is located in the northern hemisphere.
