### Latitude and Longitude

What is Latitude?
• Lines of latitude are imaginary lines that run completely around the globe
• full circles
• start at the equator at 0 degrees
• divides the earth into two hemispheres
• a.     Northern Hemisphere

b. Southern Hemisphere

Latitude (Continued)
• travel east and west
• all lines of latitude are parallel (called parallels)
Parallels

all lines of latitude are parallel (called parallels)

• on maps parallels are shown 10 or 20 degrees apart
• run from 0 to 90 degrees
• The north pole is 90 degrees N
• The South pole is 90 degrees S
What is Longitude
• Lines of longitude are imaginary lines that run completely around the globe
• full circles
• Start at the Prime Meridian at 0 degrees
• The Prime Meridian passes through Greenwich, in East London.
• Other Prime Meridians have been used
Divides the Earth into two hemispheres
• Eastern Hemisphere
• Western Hemisphere
• parallels travel north and south
• run from 0 to 180 degrees
• shown on maps at 10 or 20 degrees
• Ex. 20 degrees W, or 20 degrees E
What is the Purpose?

Latitude and Longitude together make a grid to help you locate your position on the Earth’s surface

For example Woodland Hills High School sits approximately at 40°26’19”N 79°50’13”W
