1. Latitude and Longitude

2. LATITUDE Distance in degrees N and S of the Equator
Equator is like the x-axis on a graph
00 = Equator
900 = The Poles (90 N = North Pole, 90 S = South Pole)
Lines are parallel, no matter what kind of map you have; these lines never touch each other
10 Lat = 111 km on Earth’s surface

3. Latitude of a Point on the Map
1. FIND LATITUDE
a. follow the horizontal line and write that number.
b. Then write N if the line is NORTH of the EQUATOR; write an S if it is SOUTH of the EQUATOR.

4. LONGITUDE Distance in degrees E and W of the Prime Meridian
It is like the y-axis on a graph
00 = Prime Meridian
1800 = Int’l Date Line
Lines are curved on a globe; these lines meet at the poles
Lines are straight/parallel on Mercator (rectangular) maps

5. Longitude of a Point on a Map
2. FIND LONGITUDE
a. follow the vertical line and write that number.
b. Then write an E if the point is EAST of PRIME MERIDIAN; write a W if it is WEST of the PRIME MERIDIAN

7. Time Zones Time zones correspond to lines of longitude
(Along the Equator) 15° longitude = 1 hour
(From the Prime Meridian) Moving WEST you subtract an hour for each line of longitude; moving EAST you add an hour for each line of longitude
Earth has 24 lines of longitude, 24 hours in a day and 24 time zones.
(At the International Date Line) When you cross going EAST, you ADD a calendar day; going WEST, you SUBTRACT a calendar day.
