The document discusses latitude and longitude. It explains that the equator is the reference point for latitude, with lines of latitude measured in 15 degree increments from 0 degrees at the equator to 90 degrees at the North and South Poles. The prime meridian is the reference point for longitude, with lines of longitude measured in 15 degree increments from 0 degrees at the prime meridian to 180 degrees east and west. Latitude and longitude help determine a place's climate, with higher latitudes experiencing colder temperatures and different seasons than lower latitudes.

2. LATITUDE AND LONGITUDE
In previous module, you have learned the different
imaginary lines and its description, before locating
places on the globe it is necessary to understand
more about latitude and longitude

5. LATITUDE
• THE REFERENCE POINT FOR LATITUDE IS THE EQUATOR. THE EQUATOR IS AT LATITUDE 0° (ZERO DEGREE).
STARTING FROM THE EQUATOR GOING NORTHWARD THE LINES OF LATITUDE MEASURES 15°N (FIFTEEN
DEGREES NORTH), 30°N, 45°N, 60°N, 75°N, AND 90°N (NORTH POLE) WITH EQUAL MEASUREMENT OF 15°
PER LINE.

6. LATITUDE
• BASED ON THE FIGURES ABOVE, THE GLOBE DOES NOT SHOW ALL LINES OFLATITUDE. IF YOU ARE GOING
TO LOOK FOR 50°N, IN WHICH LINES OF LATITUDE YOU SHOULD LOOK? IF YOU THINK BETWEEN 45°N AND
60°N, THEN YOU ARE RIGHT.
• MOREOVER, STARTING FROM THE EQUATOR GOING SOUTHWARD THE LINES OF LATITUDE MEASURES 15°S
(FIFTEEN DEGREES SOUTH), 30°S, 45°S, 60°S, 75°S, AND 90°S (SOUTH POLE) ALSO WITH EQUAL
MEASUREMENT OF 15° PER LINE.
• STILL BASED ON THE FIGURES ABOVE IF YOU WISH TO FIND 20°S, IN WHICH LINES OF LATITUDE YOU
SHOULD LOOK? IF YOU SAY BETWEEN 15°S AND 30°S, THEN YOU ARE CORRECT.

7. LONGITUDE
• THE REFERENCE POINT FOR LONGITUDE IS THE PRIME MERIDIAN. THE PRIME MERIDIAN IS AT LONGITUDE
0° (ZERO DEGREE). TO THE RIGHT OF PRIME MERIDIAN, THE LONGITUDE MEASURES THIS WAY: 15°E
(FIFTEEN DEGREES EAST), 30°E, 45°E, 60°E, 75°E, 90°E, AND SO ON UNTIL 180°E, WHILE TO THE LEFT OF
PRIME MERIDIAN, THE LONGITUDE MEASURES THIS WAY: 15°W (FIFTEEN DEGREES WEST), 30°W, 45°W,
60°W, 75°W, 90°W, AND SO ON UNTIL 180°W. BASED ON THE FIGURES ABOVE, THE GLOBE MEASURES A
TOTAL OF 360° DIVIDED BY 15° (DEGREES PER LINE) THEREFORE THERE ARE 24 LINES OF LONGITUDE, 12
LONGITUDES FOR WESTERN HEMISPHERE AND 12 ALSO FOR EASTERN HEMISPHERE

8. LONGITUDE
• SINCE THERE ARE EQUAL DEGREES PER LINE OF LONGITUDE, IF YOU AREGOING TO LOOK FOR 80°W, IN WHICH
LINES OF LONGITUDE YOU SHOULD LOOK? IF YOU THINK BETWEEN 75°W AND 90°W, THEN YOU ARE RIGHT. HOW
ABOUT 122°W? YOU MAY FIND IT BETWEEN 120°W AND 135°W.
• LATITUDE AND LONGITUDE ALSO HELP IN DETERMINING THE KIND OF ENVIRONMENT A PLACE MAY HAVE, FOR
EXAMPLE IF A PLACE IS LOCATED IN HIGHER LATITUDE THAT PLACE HASCOLDER TEMPERATURE AND MAY
EXPERIENCE DIFFERENT SEASONS, UNLIKE PLACES IN LOWER LATITUDE THOSE PLACES HAVE WARMER
TEMPERATURE AND MAY EXPERIENCE EXTREME WEATHER.
• HOWEVER, IF A PLACE IS IN HIGHER LONGITUDE IN WESTERN HEMISPHERE THAT PLACE MAY EXPERIENCE COLD
CLIMATE, ON THE OTHER SIDE OF THE HEMISPHERE IN EASTERN PLACES, MAY EXPERIENCE EXTREME WEATHER
LIKE STRONG TYPHOONS.
