The main points, or cardinal points, on a compass are North, South, East and West.
Take a look at a globe of the Earth. Some globes show the vertical lines, which are called longitude, and the horizontal lines, which are called latitude.
The line running around the middle of the globe, dividing the Northern and Southern Hemispheres is called the Equator. It is shown on maps as 0 degrees Latitude.
The line dividing the globe into the Eastern and Western Hemispheres is actually two geographical lines. The one running down the front of the globe is known as the Greenwich Meridian. It passes through the Greenwich Observatory in London, and is measured as 0 degrees longitude.
The line dividing the globe into the Eastern and Western Hemispheres on the back of the globe is called the International Dateline. It is measured at 180 degrees West or East. It doesn't matter which way you go around the globe, it is 180 degrees either way round.
So we call them the Northern Hemisphere, the Southern Hemisphere, the Eastern Hemisphere, and the Western Hemisphere.
Theoretically, any point that lies on the International Dateline, Greenwich Meridian or Equator, fall in one hemisphere only. It is also theoretically possible for a ship to be in all four hemispheres at the same time, if it was centered exactly over the equator on the Greenwich Meridian or International Dateline (both these points lie in the ocean).northern, southern, eastern, westernWestern hemisphere, eastern hemisphere, northern hemisphere, southern hemisphere....Totally guessing..but it sounds right.... :Pnorthern southern eastern western =]Western Hemisphere
