What are meridians?

Imagine Earth is like a big orange, and you're slicing it into pieces, meridians are like the lines you draw from top to bottom on that orange.

Like Lines on a Globe

If you look at a globe, you’ll see some lines running from the North Pole to the South Pole. These are meridians, just like the lines you’d draw if you were slicing an orange in half from top to bottom.

Meridians Help Us Find Our Way

Think of meridians as Earth’s imaginary vertical highways. They help us tell where we are on the planet, especially when we’re trying to figure out directions or time zones, just like how street signs help you find your way in a city!

Each meridian has a number, kind of like house numbers on a street. The most famous one is the Prime Meridian, which runs through Greenwich, England, and acts like Earth’s starting line for measuring east and west. Imagine Earth is like a big orange, and you're slicing it into pieces, meridians are like the lines you draw from top to bottom on that orange.
