Question

Why are north latitudes called so

Answer 1

There is an error in your query . Instead of the term north latitude it should have been horse latitude.

Horse latitudes are situated between latitude 30 and latitude 35 north and south of the equator. The region falls in an area where there is a ridge of high pressure that encircles the Earth. The Horse Latitudes got its name from the time when Spaniards carried horses aboard their ships, sailing to the colonies in the West Indies. The sailing ships sometimes were unable to move due to lack of wind and they ran out of water before reaching land. The dead and dying horses were then thrown overboard.
