Question

At a point $A$ on the earth's surface the angle of dip. $\delta$= +25°. Ata point Bon the earth's surface the angle of dip, $\delta$ = -25°. We can interpret that:

• A. A is located in the northern hemisphere and B is located in the southern hemisphere.
• B. A and B are both located in the southern hemisphere.
