What 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

LatitudeLines of LATITUDE run

around the earth parallel to the equator.

The equator is 0 degrees

Lines of latitude are measure from 0-90 degrees North and 0-90 degrees South

The equator is the LONGEST line of latitude

LongitudeLines of LONGITUDE

run from the North Pole to the South Pole

Also called meridians.They are measured in

degrees 0-180 East and 0-180 degrees West.

0 degrees is found in Greenwich, England. This line is also called the Prime Meridian

Time 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.

ExampleBuenos 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.
