Uncategorized: Practice Problem & Solution

10. 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: (2019)
A and B are both located in the northern hemisphere.
A is located in the southern hemisphere and B is located in the northern hemisphere.
A is located in the northern hemisphere and B is located in the southern hemisphere.
A and B are both located in the southern hemisphere.

Solution Explained:

To solve this problem, we apply the core principles of Uncategorized. Understanding the underlying formula is key to arriving at the correct answer below:

The angle of dip is conventionally taken as positive in the northern hemisphere and negative in the southern hemisphere. Therefore, A is in the northern hemisphere and B is in the southern hemisphere.
