Answer: Inclination (dip).
- A Declination
- B Inclination (dip)
- C Latitude
- D Azimuth
Correct answer: B. Inclination (dip)
Explanation: Magnetic inclination, or dip, is the angle the Earth's magnetic field makes with the horizontal plane. It is 0° at the magnetic equator and 90° at the magnetic poles.
