Finding your way around…
• Scientists have established a coordinate
system using circular lines to pinpoint any
place on Earth
• Earth’s Coordinate System
based on lines of
- Latitude and Longitude
Let’s Look at This

Longitudes to know
• Latitude of Prime Meridian: 0o
• International Date Line: 180o
• From the prime Meridian, you go East or
West to the International Date Line
Say LOOOOOHHHHNGITUDE
Eastern
Hemisphere
Western
Hemisphere
Longitude Reference Lines
• International Date Line – 180o on opposite
side of Earth from Prime Meridian
Imaginary line that
separates two
calendar days
Go West – gain a day
Go East – lose a day
•
•
•
•
All locations in the United States have a
(North, South) latitude
And
(East, West) longitude
• North and West
• Latitude and Longitude are measured in
degrees ,
• Which can be further divided into
minutes
There are 60 minutes (‘) per degree
Place an X at latitude 20o 32’N

• LATITUDE IS
ALWAYS WRITTEN
FIRST FOLLOWED
BY LONGITUDE
•LATITUDE AND
LONGITUDE MUST
ALWAYS INCLUDE A
DIRECTION (N or S
for latitude; E or W for
longitude)
