ScaleThe relationship between a distance on the map and the corresponding distance on the ground
•Mile: 5,280 feet; unit of distance used by the US and a few other countries
•Kilometer: .6 of a mile; the unit of distance used by the vast majority of the world

Equator
The parallel that lies at zero degrees halfway between the North Pole and South Pole

Geographic grid
The framework of crossed lines created by lines of latitude and longitude

Latitude•The distance of a place north or south of the equator
•Represented by horizontal lines on a geographic grid
•Distance from the equator affects climate

Longitude
•The distance of a place east or west of the Prime Meridian (also known as the Greenwich Meridian)
•Represented by vertical lines on a geographic grid
•Longitude affects time

LocatorA scheme that uses a grid of numbers and letters rather than degrees of latitude and longitude to pinpoint places on a map
Example: Road map
