Question

Choose the correct option :

• A. True dip is not mathematically related to apparent dip.
• B. True dip is less than apparent dip.
• C. True dip is always greater than the apparent dip.
• D. True dip is always equal to apparent dip.

Answer 1

Answer: (B)

If apparent dip circle is at an angle a with true dip circle then


As $\cos \alpha < 1$
Hence true dip $(\phi)$ is less than apparent dip$\left(\phi^{\prime}\right)$
