1. All of the following are true statements about longitude, except:
A. has its origin at the prime meridian;
B. could be determined by sailors using a device called the sextant;
C. are relatively equal in length;
D. extend east and west to 180 degrees longitude;
E. could not be determined by sailors until the introduction of the chronometer.
2. 0° longitude and 0° latitude is located:
A. in the Atlantic Ocean near the coast of Africa;
B. in Brazil;
C. over central India;
D. at the South Pole;
E. none of the above.

4. A map projection transforms the spherical earth to a flat surface. There are literally thousands of different projections. One of the first projections was developed by Gerhard Mercator in 1569 in what is now the Netherlands. The Mercator projection:
A. distorts distance but preserves area relationships;
B. preserves angular relationships but distorts area;
C. preserves distance but distorts angular relationships;
D. distorts distance and angular relationships;
E.none of the above.
5. Lines of latitude:
A. begin with the prime meridian;
B. are designated by being East or West from an origin;
C. are of equal length;
D. become shorter away from the equator;
E. none of the above.
