Which of the following statements is correct about the angle of dip at various points on Earth?
A
The angle of dip is zero at the equator and 90 degrees at the magnetic poles.
B
The angle of dip is greater at higher altitudes than at lower altitudes
C
The angle of dip is positive in the northern hemisphere and negative in the southern hemisphere.
D
The angle of dip is constant at all points on Earth
Verified Correct Answer: A.
Physical Principles & Numerical Solution
The angle of dip is the angle between the direction of the intensity of the total magnetic field of Earth and a horizontal line in the magnetic meridian. It is also known as the magnetic inclination. The angle of dip ranges from 0 degrees at the magnetic equator to 90 degrees at the magnetic poles.
