Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to read latitude and longitude on a map [title] Get familiar with the concept of latitude. [step] Latitude is a measure of distance north or south of the equator, which is an imaginary horizontal line around the exact mid-point of the earth between the 2 poles. The earth is divided up into 180 latitude lines on either side of the equator, called parallels.

Ending1: These lines connect landmasses and other objects closest to the equator. If you look at both poles, you can see where they connect. Ending2: The prevailing temperature usually ranges between 54 and 77 degrees fahrenheit, with 31 degrees of latitude in the western hemisphere and 70 degrees in the southern hemisphere. [substeps] The heat often determines the direction of latitude. Ending3: [substeps] Since latitude is a measurement of mass, both angular and independent earth arcs are identical. Both poles give the heading of a particular set of poles depending on their latitude side. Ending4: These parallels run horizontally around the earth, parallel to the equator. 90 of them are north of the equator, while the other 90 are south of it.
