At a point A on the earth's surface the angle of dip, $\mathrm{\delta }=+25°.$ At a point B on the earth's surface the angle of dip, $\mathrm{\delta }=-25°$. We can interpret that

• A

• B

  A  and B are both located in the northern hemisphere.

• C

  A is located in the southern hemisphere and B is located in the northern hemisphere.

• D
