12. Projections
All maps are projections of the Earth’s curved surface onto a flat page.

13. Distortion
Because maps represent a curved, 3-dimensional, surface on a flat, 2-dimensional surface, there is always distortion: all maps are wrong in some way!
Distortion: Inaccuracies on all maps because of projection.
Maps can distort the size, shape, direction, and distance.
“All maps lie flat and all flat maps lie.”

21. Compass Rose
A design on a map that shows direction: north, east, south and west. North is always at the top of the compass rose; south is always at the bottom.

22. Legend

23. Map Legend
The legend will tell what type of information is found on a map and the meaning of symbols.
Symbols can change from map to map. There are both line symbols and point symbols. Font can also be used to distinguish important information on a map.
Maps can have more than one legend.

27. Longitude/Latitude
Latitudes: Lines that run east and west around the Earth. These lines measure distances north and south of the Equator.
Longitudes: Lines that run from the North Pole to the South Pole. These lines measure distances east and west of the Prime Meridian.
*** When determining a point of intersection, latitude is read always first.

28. Equator/Prime Meridian
Equator: An imaginary line drawn halfway between the North & South poles. (0° latitude)
Prime Meridian: An imaginary line drawn from the North Pole to the South Pole. (0° longitude)

29. Tropics
Two lines of latitude are known as tropics: The Tropic of Cancer (23.5°N) and the Tropic of Capricorn. (23.5°S)
The area is know for a relatively constant amount of sunlight throughout the year.
Usually countries in the tropics have a wet season and a dry season.

30. Latitude and Longitude Practice

31. Time zones
Time zones created when rail travel allowed people to move very fast from one place to another.
United States creates 4 time zones in 1883
Great Britain helps create world time zones in 1884.

32. Time zones continued
As a general rule, there is a different time zone for every 15° Longitude
China has only one time zone!
How do time zones affect our lives every day?

34. International Date Line
Through the Pacific runs the international date line
Here the date changes depending on direction of travel.
If you fly from Hawaii to Australia, you’ll be a day ahead of when you left.

35. LOCATION Where are we? Absolute Location Relative Location
A latitude and longitude (global location) or a street address (local location).
Paris France is 48o North Latitude and 2o East Longitude.
The White House is located at 1600 Pennsylvania Ave.
Relative Location
Described by landmarks, time, direction or distance. From one place to another.
Go 1 mile west on main street and turn left for 1 block.
