In which context is the Prime Meridian important?

For determining elevation
For establishing real-time weather reports
For defining 0 degrees longitude
For mapping natural resources

The correct answer is: For defining 0 degrees longitude

The Prime Meridian is significant as it serves as the reference line for establishing 0 degrees longitude. This means it is the baseline from which all other longitudes are measured, facilitating navigation and geographical orientation. It runs through Greenwich, England, and its location is crucial for global positioning systems and for establishing time zones, which are based on longitudinal divisions. By defining 0 degrees longitude, the Prime Meridian plays a fundamental role in cartography and geography, helping to create a standardized framework for understanding global geography.
