As we all know, the world is a big sphere which can be divided according to two imaginary lines. The horizontal one is called Equator, and the other (vertical) is known as the Greenwich Meridian. You can easily see this taking an orange; if you cut it from the top to the bottom you'll obtain two equal parts, and your cut would represent the Greenwich Meridian. If you had taken the same orange but cutting it from the left to the right your cut would represent the Equator and you had divided your orange in two parts.
In the Globe these two parts are called hemispheres; Northern and Southern hemisphere.
And what's about Ireland? Where is it? Let me show you a map firstly:
(Click it for a better view)
Ireland is situated on the Northern hemisphere and a little to the west of the Greenwich Meridian so we say that it's located on the Northwestern hemisphere.
It's an small island that we can find beside United Kingdom one (although the Northeast part of the island belongs to United Kingdom) in the eastern part of North Atlantic Ocean and on Northwest of Spain.
And it belongs to european continent.
