Which of the following statements is correct about the angle of dip at various points on Earth?
The angle of dip is zero at the equator and 90 degrees at the magnetic poles.
The angle of dip is greater at higher altitudes than at lower altitudes
The angle of dip is positive in the northern hemisphere and negative in the southern hemisphere.
The angle of dip is constant at all points on Earth
설명
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.
