2 THE ANGULAR DISTANCE NORTH OR SOUTH OF THE EQUATOR PARALLELS OF LATITUDE CONSISTS OF ALL POINTS HAVING THE SAME LATITUDE LIEING ON A CIRCLE WHICH IS PARALLEL TO THE EQUATOR LATITUDE INCREASES TO A MAXIMUM OF 90º NORTH AND 90º SOUTH OF THE EQUATOR

3 WHEN WRITING A LOCATIONS LATITUDE YOU MUST INCLUDE AN N OR AN S EQUATOR- MARKS THE MIDDLE LOCATION ON EARTHS SURFACE, HALFWAY BETWEEN THE GEOGRAPHIC NORTH AND SOUTH POLES TROPICS – TROPIC OF CANCER 23.5º N TROPIC OF CAPRICORN 23.5º S ARCTIC CIRCLE 66.5º N ANTARCTIC CIRCLE 66.5º S

4 THE ALTITUDE OF POLARIS EQUALS THE DEGREE OF LATITUDE IN THE NORTHERN HEMISPHERE ALTITUDE OF POLARIS AT THE EQUATOR= NORTH POLE= ZENITH – THE POINT DIRECTLY OVERHEAD 0º0º 90º

5 IS AN ANGULAR DISTANCE EAST OR WEST OF THE PRIME MERIDIAN

6 MERIDIAN OF LONGITUDE- A SEMI-CIRCLE ON THE SURFACE OF THE EARTH CONNECTING THE NORTH AND SOUTH POLES LONGITUDE INCREASES EAST OR WEST OF THE PRIME MERIDIAN TO 180º PRIME MERIDIAN - THE MERIDIAN OF ZERO LONGITUDE WHICH PASSES THROUGH GREENWICH, ENGLAND

7 LONGITUDE CAN BE CALCULATED USING THE TIME DIFFERENCE FROM YOUR LOCATION TO GREENWICH, ENGLAND. 15º = 1 HOUR THE INTERNATIONAL DATE LINE IS LOCATED 180º FROM THE PRIME MERIDIAN YOUR TIME IS AHEAD OF GREENWICH TO THE EAST, AND BEHIND GREENWICH TO THE WEST WHEN RECORDING A LOCATIONS LONGITUDE YOU MUST INCLUDE EITHER E OR W

8 YOU MUST BE ABLE TO ACCURATELY READ OR PLOT ANY LOCATION USING THIS COORDINATE SYSTEM! 42º30N, 75º15W FOR EXAMPLE LATITUDE AND LONGITUDE ARE MEASURED IN DEGREES AND MINUTES 1 DEGREE = 60 MINUTES
