2D Wong Tsz Hin Donald (32)Aprime meridianis a line oflongitude, at which longitude is defined to be 0. A prime meridian and its opposite in a 360-system, at 180 longitude form agreat circle. This great circle divides theEarth, into two hemispheres. If one uses directions of East and West from a defined prime meridian, they can then be called Eastern HemisphereandWestern Hemisphere.

My reflectionI want to go to the Royal Observatory in Greenwich because their government use a line to divide it into two hemispheres. Thus I can step onto the two hemispheres at one time. If I go there, I can learn more about Prime Meridian, especially at the method of measurement at Prime Meridian.Rio de Janeiro 43 10 19 WHong Kong 114 10' 0" E Some Countries longitudeJerusalem 35 13 47.1 EFlorence 1115 ERome 12 27 08.4 ENew York 74 0' 23" WTokyo 139 45' 5" EGreenwich 0 00 00 W
