2. Latitude:
Equator = 0 degrees
Parallel lines
Up to 90 degrees North or South
Equator divides Northern and Southern Hemispheres
Run East and West
Give North and South direction
from Equator

3. 90 degrees North 90 degrees South Northern Hemisphere
Equator 0 degrees
Southern Hemisphere
90 degrees South

4. Longitude: Prime Meridian (PM)= 0 degrees
Non Parallel (perpendicular) lines called Meridians
Up to 180 degrees East and West
180 degrees is the International Date Line (IDL)
Prime Meridian divides Eastern and Western Hemispheres
Run North and South
Give East and West direction from PM

5. N W E S Prime Meridian 0 degrees International Date Line 180 degrees
Western Hemisphere
Eastern Hemisphere
Prime Meridian 0 degrees
International Date Line 180 degrees

6. Earths Movement::
Revolution: around sun = 365 ¼ days
Every 4 years = Leap Year when add the extra day—February 29
Rotation on Axis = 1 time per day—Rotates East
Atmosphere keeps us from noticing the movement

7. Seasons: Solstice = Winter/Summer Equinox = Spring/Fall
Earth is tilted 23 ½ degrees on its Axis
Tropic of Cancer = 23 ½ degrees North
Tropic of Capricorn = 23 ½ degrees South
Tropic of Cancer
Equator
Tropic of Capricorn

8. Exercise:
Please tell what direction you would travel to go from point A coordinates to point B coordinates. Take the shortest route—what direction would get you there quickest?
A Coordinates B Coordinates Cardinal/ Intermediate
Direction Traveled S
15 W E
91 N W
86 S E
33 S, S, 109 W
