Meaning of longitudes - SS1 Geography Lesson Note

Longitudes are imaginary vertical lines on the Earth's surface that run from the North Pole to the South Pole. They are also known as meridians and help us pinpoint locations on the Earth's east-west axis.

The starting point for measuring longitudes is the Prime Meridian, which runs through Greenwich, England and is designated as 0 degrees longitude. Longitudes are crucial for determining time zones and navigation.
