The dip angle is:
A)another term for magnetic declination.
B)a measure of the tendency for a compass to point south.
C)close to or at zero near the equator.
D)close to or at zero just north of Hudson Bay.

Question

Quizplus · Accepted Answer

The dip angle, also known as the magnetic inclination, is the angle between the horizontal plane and the direction of the Earth's magnetic field. It is close to or at zero near the equator, where the magnetic field lines are almost parallel to the surface of the Earth. It increases as one moves towards the magnetic poles. Therefore, the dip angle is close to or at zero just north of Hudson Bay would be incorrect because that location is closer to the North Magnetic Pole where the dip angle is not zero. Option A is also incorrect because magnetic declination is the angle between magnetic north and true north, which is different from the dip angle. Option B is incorrect because the dip angle does not measure the tendency for a compass to point south.
