1. Introduction to Longitude & Latitude
Learning about Absolute Location

2. Relative Location Where you are in relationship to other things!
For example:
Direction (North, South, East, or West)
Physical (streets or structures)
Distance (feet, yards, or miles)
You have a flat tire and no spare tire. You need help.
Please tell the tow truck driver how to find you!

3. Relative Location: Compass & Cardinal DirectionsW E S NE SW NW SE N W E S

4. N W E S NE SW NW SE
Relative Location
You are here!

5. Absolute Location
Your boat has ran out of fuel in the middle of the ocean. You need help
Tell the coast guard how to find you.
What do you do if there is nothing available to establish a relationship with.

6. Absolute Location This is earth!
It is an imaginary grid system of lines covering the entire world.
The main two divide the earth into hemispheres (halves)
Equator and Prime Meridian
There are two sets of lines. Lines of Longitude and Latitude
Prime Meridian
Equator
This is earth!

7. Lines of Latitude Lines of Latitude Starting Point: Equator 0 degrees
There are 360 lines (360 degrees in a circle)
Run from Left to Right
However, they measure North and South

8. Lines of Longitude Lines of Longitude Starting point: Prime Meridian
0 degrees
There are 360 lines (360 degrees in a sphere)
Run from up and down
However, they measure East to West
The starting point is the Prime 0 degrees

9. Question 1: Which letter represents the EQUATOR
Question 2: Which letter represents the PRIME MERIDIAN
Question 3: Lines of Latitude are the color Green. Which letter represents 30 degrees North and 30 degrees South?
Question 4: Lines of Longitude are the color blue. Which letter represents 30 degrees East and 30 degrees West?
