The point of latitude and longitude is be able
to pinpoint any location on the Earth.
They form a grid that should look kind of
familiar…

Latitude lines:
 Are parallel (never meet or touch)
 Run East to West
 Range from 0°–90° North and South
 Dumb way to remember:
▪ Latitude = “Laddertude”

Equator
 Half-way between North and South Poles
 0 ° , Neither North nor South

Tropic of Cancer
 23.5° North

Tropic of Capricorn
 23.5° South

Arctic Circle
 66.5° North

Antarctic Circle
 66.5° South
Yes, these are
important and
we will talk
about them
further later
on.

Longitude lines:
 All meet at the North and South Poles
 Run North to South
 Range from 0°–180° East and West
 Dumb way to remember:
▪ Longitude = Long, tall telephone poles

Prime Meridian
 Runs through
Royal Observatory,
Greenwich, England
 0°, neither East nor West

International Date Line

For example:
 Farmington, Utah 40°N, 111°W
N,W - All of North
America
•N,E – Most of Europe,
Africa, and Asia

and a chunk of Africa

360° ÷ 24
hours = 15°

You need to be able to convert times to local time by looking at a
map.
