1. Latitude and Longitude

2. Latitude Imaginary horizontal lines that run across the earth.
They measure degrees north and south of the equator.
They’re called parallels because they never touch.

3. Important Lines of Latitude
Equator
Most important
Located at 0°
Separates earth into north & south hemispheres (halves)

4. Important Lines of Latitude
Tropic of Cancer
Tropic of Capricorn
23.5° north
farthest point north that receives direct sunlight on or around June 21st
23.5° south
farthest point south that receives direct sunlight on or around December 21st

5. Important Lines of Latitude
Arctic Circle
Antarctic Circle
66.5° north
66.5° south

6. Rule of thumb
As a general rule, the farther north or south you go from the equator, the colder the climate.

7. Longitude
Imaginary lines that run up and down the earth but they measure in degrees east and west from the Prime Meridian.
Also known as meridians

8. Important Lines of Longitude
International Dateline
Prime Meridian
Located at 180° longintude
It is where the start of each new day begins
Most important line of longitude
Located at 0° longitude
Helps to separate the earth into the east & west hemispheres (halves)

9. Rule of Thumb Longitude lines have nothing to do with climate.
They are associated with time zones. About every 15° longitude is a new time zone.

11. Latitude & Longitude Rules
Find latitude first.
Determine how far north or south of the equator the latitude is.
Stay on the road!! Lines of latitude will curve because the earth is round.
Trace the line of latitude at 45°N.

12. Latitude & Longitude Rules
Find longitude second.
a. Determine how far east or west of the Prime Meridian the longitude is.
b. Stay on the road!!
Lines of longitude will
curve because the
earth is round.
Trace the line of longitude at 75°W.

13. Latitude & Longitude Rules
Add tags.
Latitude: N or S tag after it.
Longitude: E or W tag after it.
Remember degrees (°) after your numbers.
Example, 41°N, 81°W. Look at a U.S. map. Which city has these coordinates?

14. Sample X The red X is at 15°N, 30°E.
What are the coordinates of the green X?
