A Parallel

A Great Circle

A Rhumb Line

a Grid Line

Question 2) The angle between the Earth’s magnetic field and the horizontal is referred to as:

Deviation

Variation

Slip

Dip

Correct! Wrong!

Magnetic dip is the angle between the horizontal axis and the Earth’s magnetic field lines. Dip will increase the closer your position to the magnetic poles.

Question 3) A magnetic compass is designed to use the horizontal component of the earth’s magnetic field. The compass will be most accurate:

At mid-latitudes

At low latitudes

Over the geographic poles

Over the magnetic poles

Correct! Wrong!

A magnetic compass is most accurate at low latitudes as it’s the furthest point away from the magnetic poles where the compass dip error has least effect.
