21. I would ask you to consider something-sailors who stayed North of a certain line of latitude never saw the Southern Cross. 22. The 1 : 250, 000 sheets are defined using lines of latitude and longitude, each extending 1?north-south and 2?east-west. 23. USGS maps include lines of latitude and longitude, as well as a more precise grid called a Universal Transverse Mercator overlay. 24. Parallels ( i . e . lines of latitude ) are concentric meridian, shapes are not distorted, but elsewhere they are. 25.

Above the stage, a globe showed the lines of latitude , while the Milky Way and phases of the moon appeared on the stage floor. 30. The lines of latitude are all parallel to the equator, so they will become perfect circles centered on the origin " z " = 0.
