262 - What is the significance of the Prime Meridian?

The Prime Meridian is a very important line that helps us find our place on the Earth. It's an imaginary line that runs from the North Pole to the South Pole, passing through a place called Greenwich in London, England.

Here's why it's significant:

1. Time zone separation: The Prime Meridian helps separate the world into time zones. Every place east or west of it has a different time.
2. Navigation: It's a reference point for sailors, pilots, and travelers to find their way around the world.
3. Mapping: The Prime Meridian is used to create maps, and all locations on Earth are measured in relation to it.

Think of it like a big line that divides the world into two parts: East and West.
