Latitude and Longitude

How do we find places on maps?


What is Latitude?

  • Lines of Latitude run horizontally
  • Latitude is measured in degrees.
  • The Equator is 0 degrees Latitude.
  • Lines of Latitude locate places North or South of the Equator.
  • The North Pole is 90 degrees N Latitude, and the South Pole is 90 degrees S Latitude.
  • Lines of Longitude run vertically.
  • They are also called Meridians.
  • The Prime Meridian is found in Greenwich, England.
  • The Prime Meridian is 0 degrees Longitude.
  • Lines of Longitude locate places East or West of the Prime Meridian.
  • There are 180 degrees of east Longitude, and 180 degrees of west Longitude.
Western Hemisphere

Eastern Hemisphere

Places located east of the Prime Meridian have an east longitude (E) address. Places located west of the Prime Meridian have a west longitude (W) address.

Prime MeridianThe Prime Meridian (0°) and the 180° line split the earth into the Western Hemisphere and Eastern Hemisphere.Prime Meridian

time zones
Time Zones
  • Time zones are broad strips that measure 15 degrees wide.
  • Time zones differ from their neighboring time zones by 1 hour.
  • Canada has 5 1/2 time zones, Newfoundland, Atlantic, Eastern, Central, Mountain, and Pacific.
  • In the Spring we shift the clocks 1 hour ahead. This is called Daylight Saving Time.
  • In the Fall we shift the clocks 1 hour back.

Local Time and Universal Time

Local Time- is what we use everyday, and regulates our lives.

Examples of Local Time are: meal time, sleep time, work time, and school time

Universal Time-is what we use when we need a time that is agreed upon marking time world-wide. Exact time

An example when Universal Time was used was when a supernova in 1987 was first seen. Astronomers, and Astronauts use Universal Time..

  • Greenwich Mean Time- is the time that is registered at Greenwich, England.

**Greenwich Mean Time is another name for Universal Time.

The International Dateline was established following the 180th meridian, where ever we cross it the date advances 1 day ( if you are going west), or goes back 1 day (if you are going east).

Greenwich, England is the logical starting point for time zones
  • The world rotates west to east (counterclockwise), time zones to the east are ahead of the those time zones to the west
another cheesy saying

Time is forward to all places to the east


Time is backward to all places to the west

east increase west less 1 hr per l5
East Increase – West Less(1 hr per l5°)

If it 9 p.m. at Position D, what time is it at position C? Position B?

If it is 1 p.m. at Position X, at which location is the time 5 p.m.



Thunder Bay




It’s still daylight in California



Those light are Boston, New York, Philadelphia and Washington.



Puerto Rico



Mexico City




1.What do lines of Latitude and Longitude combine to make?

A grid.

2.Compare and Contrast Latitude and Longitude.

Latitude- horizontal, north- south, parallels

Longitude- vertical, east-west, meridians

3.What is 0 degrees Latitude?


4.What is 0 degrees Longitude?

Prime Meridian

5.How many time zones do we have in the U.S.A.?

4- Eastern, Central, Mountain, Pacific

6. Explain the difference between Local Time, and Universal Time.

Local time- used everyday

Universal Time- is used for a planetary event, or for astronomy
