Latitude and longitude

Latitude (shown as a horizontal line) is measured in degrees north or degrees south of the equator, which is the line around the exact middle of the earth.

Lines of latitude are often referred to as parallels. Arctic Circle (66° 30'' N)

Antarctic Circle (66° 30'' S)

Tropic of Cancer (23° 30'' N)

Tropic of Capricorn (23° 30'' S)

Longitude (shown as a vertical line) is measured in degrees east or west of something called the Prime Meridian. This is the line going from the North Pole to the South Pole and running through the middle of the Greenwich Observatory in London.

Lines of longitude are often referred to as meridians.

Prime Meridian

Longitude

Britain was a world leader in exploration and map making. Therefore, navigators of other nations often used British maps. As a result, in 1884 the meridian of Greenwich was adopted throughout most of the world as the Prime Meridian.

Why is the Prime Meridian in Greenwich?

Simple RulesLatitude is shown by horizontal lines

going around the earth from the North to the South Pole.

Longitude shows how far east or west something is from a line called the Greenwich Meridian.

Co-ordinates must have the latitude followed by the longitude. Eg. (20˚S, 20˚W)

Practice1. Cairo: (30°N, 31°E)2. Beijing: (39°N, 116°E)3. Sydney: (33°S, 151°E)4. Berlin: (52°N, 13°E)5. Mexico City: (19°N, 99°W)6. London: (51°N, 0°W)
