LONGITUDE

Today in class we turned on the lights for the first time this year. It was pretty cool because I have never seen the things in the class under different lighting. We also learned about longitude. Longitude is the geographic coordinate that specifies east to west position on the World Map. The Prime Meridian is the 0 degree longitude line that passes through a place in England called Greenwich. Greenwich is weird because its pronounced Grin-Itch not Green-Itch. Longitude lines are also called meridians. Meridians are furthest apart at the Equator and get closer at the poles. All the meridians are equal in length and they are half of great circles around the globe.
