QSL Latitude and Longitude Adventures

By Donna LaRoche


Class Discussion Questions and Facts

· Why are latitude and longitude lines helpful?  What do lines tell map readers?  What are degrees, minutes, seconds? 

· Degrees contain 60 minutes of arc.

· Minutes contain 60 seconds of arc. 

· Seconds can be further divided into tenths, hundredths, or even thousandths.  Example:  35° 43’9” means 35 degrees, 43 minutes and 9 seconds.

· Latitude is the distance North or South of the equator, marked across the map and/or globe. Degrees latitude are numbered from 0° to 90° north and south. Each degree of latitude is approximately 69 miles (111 km) apart; there is a variation due to the fact that the earth is not a perfect sphere.

· Longitude is the distance East or West of the prime meridian, marked down the map and/or globe. The vertical longitude lines are also known as meridians. Zero degrees longitude is located at Greenwich, England (0°). The degrees continue 180° east and 180° west where they meet and form the International Date Line in the Pacific Ocean.
