1
Latitude, Longitude, and Time Zones
2
Lat. and Long. form a grid 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…
3
Latitude Lines 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”
4
Important Lines Of Latitude
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.
5
Longitude Lines 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
6
Important Lines Of Longitude
Prime Meridian Runs through Royal Observatory, Greenwich, England 0°, neither East nor West International Date Line Opposite Prime Meridian 180°, both East and West
7
Putting the coordinates together
Latitude, Longitude For example: Farmington, Utah 40°N, 111°W
8
The inhabited continents kind of match up with the grid.
N,W - All of North America N,E – Most of Europe, Africa, and Asia S, W – Most of South America S, E – All of Australia and a chunk of Africa
9
Time Zones 360° ÷ 24 hours = 15° longitude for every hour of the day.
10
But because countries and states don’t match the longitude lines perfectly, we’ve tweaked the time zone lines to fit our needs.
11
West is less! LA is three hours behind New York.
You need to be able to convert times to local time by looking at a map.
