Line of latitude
From Tardis Wiki, the free Doctor Who reference
According to a book owned by Chloe Webber, the Equator appeared on globes of the planet Earth together with other lines that ran around the globe parallel to the Equator, known as parallels or lines of latitude. Latitude was measured in degrees between the Equator (0 degrees latitude) and the poles (90 degrees latitude). The latitude of any place between them was the angle formed at the centre of the Earth between the place and the Equator. (TV: Fear Her [+]Loading...["Fear Her (TV story)"])
