## What are the lines of longitude also called as?

Answer:

### Answer by Student

• The lines of longitude are also called as meridians .
• They are imaginary lines that divide the Earth vertically.

### Detailed Explanation by Teachoo

• The lines of longitude are also called as meridians because they run north to south, from pole to pole, and intersect at the poles . The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, south-east London on the island of Great Britain¹. Positive longitudes are east of the prime meridian, and negative ones are west.
• The lines of longitude are imaginary lines that divide the Earth vertically , or from front to back. They measure how far a place is from the prime meridian, in degrees east or west. For example, if a place is at 30°E longitude, it means it is 30 degrees east of the prime meridian. If a place is at 45°W longitude, it means it is 45 degrees west of the prime meridian.
