Meridians

Meridians are imaginary lines on the Earth that run from the North Pole to the South Pole. They help us determine longitude, which measures how far east or west a place is from the Prime Meridian, located at 0 degrees longitude in Greenwich, England. Meridians are spaced 15 degrees apart, and they are essential for navigation and map-making. By using meridians, we can pinpoint exact locations on the globe and understand how different places relate to one another in terms of distance and direction.
