1. The answer is latitude. There are 180 imaginary lines of latitudes from north pole to south pole, created by humans to map the earth. These lines encircle the earth and are parallel to each other. Degrees of latitude are divided into 60 minutes and those minutes are then divided into 60 seconds. Moving from one minute of latitude to another covers approximately 1.8 kilometers (1.1 miles).
2. The answer is C. The equator is 0-degree latitude while those in the northernmost and southernmost poles are both 90 degrees latitudes north and south respectively. An arcdegree in the equatorial regions is higher than at the poles due to the curvature of the earth.
The answer is A. These, like latitudes, are 360 imaginary lines of longitudes that run 90 degrees to latitudes, and are created by humans to map the earth. They all pass at the point in the north and south pole , parallel to one another. There are 4 minutes between two latitudes. The Greenwich Meridian is the 0-degree longitude.
