Meridian lines are imaginary lines that run from the North Pole to the South Pole on the Earth's surface. They are used to measure longitude, which is the distance east or west of the Prime Meridian (0 degrees longitude) that passes through Greenwich, England.

In astronomy, a meridian is an imaginary line that runs from the north point on the horizon, through the zenith (the point directly overhead), to the south point on the horizon. It is used as a reference point for determining the position of celestial objects in the sky. The meridian is important for astronomers as it helps them track the movement of stars, planets, and other celestial bodies across the sky. By observing when objects cross the meridian, astronomers can accurately measure their positions and track their movements. **
