Hemispheres

     Geographers divide the earth into hemispheres. Everything north of the equator is in the Northern Hemisphere, while everything south of the equator is in the Southern Hemisphere. The Western Hemisphere is west of the Prime Meridian, while the Eastern Hemisphere is east of the Prime Meridian. The hemispheres both end at the International Date Line. The United States is in the Northern and Western Hemispheres. West Palm Beach, is 80° west of the Prme Meridian and 27° north of the equator. This is commonly expressed as 27°N, 80°W.

     We measure the hours of the day by the turning of the earth. The time of day at any particular moment depends on where you are. When it is noon in Greenwich, England, it is midnight along the International Date Line.
