1The Imaginary Lines Around the Earth Latitude, Longitude, Time Zones, Tropics and Climate Zones. K. Shadle
2What are all of those lines? There are many imaginary lines that circle the earth, but what are they are why are they there?LatitudeLongitudeTime ZonesClimate ZonesThe TropicsThe Arctic and Antarctic Circles
3LatitudeLines of LATITUDE run around the earth parallel to the equator.The equator is 0 degreesLines of latitude are measure from 0-90 degrees North and 0-90 degrees SouthThe equator is the LONGEST line of latitude
4Longitude Lines of LONGITUDE run from the North Pole to the South Pole Also called meridians.They are measured in degrees East and degrees West.0 degrees is found in Greenwich, England. This line is also called the Prime Meridian
5Time ZonesLongitude is used to help determine Time Zones. The line that runs through the Bering Strait is the International Dateline.There are 24 time zones because there are 24 hours in a day.
6ExampleBuenos Aires is west of London, and they are separated by 4 time zones.This means that when it is noon in Buenos Aires it is 4 pm in London.When it is noon in London it is 8 am in Buenos Aires.
