16 LINES <strong>OF</strong> LATITUDE AND LONGITUDE Knowing the location of the earth’s seven continents and five oceans is valuable information to apply as we explore the skills needed to ‘locate’ a place. Your home address identifies your ‘local’ position. However, every place on earth has an absolute location identified through the use of lines of latitude and longitude. The absolute location of a place doesn’t change. These are the concepts (ideas) which we now explore. The local location or address of the Central Bank (Twin Towers) in Port-of- Spain is Independence Square Port of Spain, Trinidad and Tobago. This address is in relation to the many other buildings located in this general area. In contrast, to state that it lies at 10°38'55.1"N 61°30'44.6"W is to pinpoint a position at which only the Central Bank is located (absolute). Among the things you observe when you look at a globe is that there is an overlay of lines that create a grid on the earth. This grid is known as a graticule. Those lines drawn in a North-South (sky to earth) or vertical direction are called lines of Longitude. The others drawn in an East-West or horizontal direction are called lines of Latitude. Traditionally, both lines of Longitude and Latitude are measured in degrees. They had been plotted many years ago by scientists and geographers. Though we see real lines they are only imaginary guide lines. These lines assist us to locate a place on Earth. LINES <strong>OF</strong> LONGITUDE
17 Longitude lines are not parallel since they meet at the poles. There are 24 lines of Longitude and there were different lines of longitude being used as a starting point. However, a universal agreement was reached to designate one common longitude line as the PRIME MERIDIAN. This line at 0 o is the Greenwich Meridian or the zero degrees (0 o ) line of Longitude. It passes through the town of Greenwich in England. Now with 0 o being in the centre, the lines are identified by measurements to both the east and the west using zero degrees as their starting point. Consequently, we read eastwards from the 0 o line to the 180 0 line East Longitude and westwards from the 0 0 to the 180 0 West Longitude. The 180 0 East and 180 0 West Longitude line is the same line. ACTIVITY ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,, The International Dateline THE TIME FACTOR Lines of Longitude are referred to as meridians (midday lines) because all places along any line of Longitude have midday (noon) at the same time. The 180th Meridian directly intersects four (4) countries, and those countries could have had different time zones within their borders. They include Fiji, Kiribati, Russia, and the United States. The International Date Line follows part of the 180 o longitude line but diverts around these land masses to prevent such a confusing situation.
