What Is the Prime Meridian? — Reading Comprehension

The Prime Meridian is an imaginary line that divides the Earth into two halves: the Eastern Hemisphere and the Western Hemisphere. It runs from the North Pole to the South Pole and is marked as 0 degrees longitude.

The Prime Meridian goes through a place called Greenwich, in London, England. That’s why it’s also called the Greenwich Meridian. Just like the Equator helps us measure how far north or south a place is, the Prime Meridian helps us measure how far east or west a place is using longitude.

The Prime Meridian is very important for making maps and telling time. It is the starting point for all other longitude lines. It also helps create time zones across the world. The time at the Prime Meridian is called Greenwich Mean Time or GMT.

Understanding the Prime Meridian helps us read globes, use GPS, and understand where places are on Earth. It’s one of the most important lines used in geography!
