Part A: Determining Latitude

1. Figure A represents Earth, with point B its

center. Locate the equator on the globe.

Sketch and label the equator on Figure A. Label the Northern

Hemisphere and Southern Hemisphere on Figure A.

2. On Figure A, make an angle by drawing a line from point A on the

equator to point B (the center of Earth). Then extend the line from

point B to point C in the Northern Hemisphere. The angle you have

drawn (aABC) is 45°. By definition of latitude, point C is located at

45°N latitude.

3. Draw a line on Figure A through point C that is also parallel to the

equator. What is the latitude at all points on this line? Record this

number on the line you draw.

4. Draw a line on Figure A from point D to point B. Using a protractor,

measure aABD on your paper. Then draw a line parallel to the

equator that also goes through point D. Label the line with its

proper latitude.

5. How many degrees of latitude separate the latitude lines (or

parallels) on the globe that you are using? Record the degrees

of latitude.
