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 RightHowever, they measure North and South
8 Lines 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
9 Question 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?
