Parallels and Meridians - Concepts - Chapter 2 Class 6 Geography - Latitudes and Longitudes - Geography

Meridians or Longitude 

• The globe has two sets of circles: parallels and meridians
• Parallels run from east to west and are parallel to the equator
• Meridians run from north to south and pass through the poles
• Half of a meridian between the poles is called a semicircle
• The parallels and meridians intersect at right angles ( 90° )
• The network of parallels and meridians on a globe is called the earth’s grid or the geographic grid
• The parallels and meridians can be used to define the location and direction of any place on the globe or on the map
