1Introduction to Longitude & Latitude Learning about Absolute Location
2Relative 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!
5Absolute LocationYour boat has ran out of fuel in the middle of the ocean. You need helpTell the coast guard how to find you.What do you do if there is nothing available to establish a relationship with.
6Absolute 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 MeridianThere are two sets of lines. Lines of Longitude and LatitudePrime MeridianEquatorThis is earth!
7Lines of Latitude Lines of Latitude Starting Point: Equator 0 degrees There are 360 lines (360 degrees in a circle)Run from Left to RightHowever, they measure North and South
8Lines of Longitude Lines of Longitude Starting point: Prime Meridian 0 degreesThere are 360 lines (360 degrees in a sphere)Run from up and downHowever, they measure East to WestThe starting point is the Prime 0 degrees
9Question 1: Which letter represents the EQUATOR Question 2: Which letter represents the PRIME MERIDIANQuestion 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?
