Latitude These are horizontallines, along the X-axis. These are horizontal lines, along the X-axis. Latitude is the distance in o North or o South of the equator Latitude is the distance in o North or o South of the equator All points along the equator have a value of 0 o latitude. All points along the equator have a value of 0 o latitude. *Highlight the equator below in one color.

Longitude These are vertical lines, along the Y axis. These are vertical lines, along the Y axis. Longitude is the distance in o East or o West of the Prime Meridian Longitude is the distance in o East or o West of the Prime Meridian All points along the prime meridian have a value of 0 o longitude. All points along the prime meridian have a value of 0 o longitude. *Highlight the Prime Meridian below in another color.

Hemispheres The earth is divided into halves, or hemispheres by the equator and Prime Meridian The earth is divided into halves, or hemispheres by the equator and Prime Meridian The equator divides the Southern & Northern hemispheres The equator divides the Southern & Northern hemispheres The Prime Meridian divides the Eastern & Western hemispheres. The Prime Meridian divides the Eastern & Western hemispheres. The origin is the point at coordinates (0,0) where the equator and Prime Meridian intersect The origin is the point at coordinates (0,0) where the equator and Prime Meridian intersect

Absolute Location The latitude and longitude coordinate points of a place The latitude and longitude coordinate points of a place
