If you look at a globe with a map of the world, you will see lines that go up and down. Each of the lines go through both the north pole at the top of the globe and through the south pole at the bottom of the globe. These lines that go up and down are called meridians. They are also called lines of longitude.
Meridians are important for navigation. |
