Give a geographical reason for: Great circles are the shortest routes between two places.
Answers
Great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere’s centre and was known by mathematicians before the time of Columbus. Until the 19th century ships generally sailed along rhumb lines, which made use of prevailing winds and fixed compass headings. The development of steamships in the 19th century allowed complete independence from the winds, removing the major uncertainty for sailors trying to follow a geometrically prescribed route.
Answer:
great circles are the shortest routes between two places ..the reason is the earth being an oblate spheroid is flattened at the poles and is bulged at the centre,and when an object moves around the equator or great circles it has to travel a greater distance than at the poles which causes it to acclerate and attain a speed of 1670 km/hr ...and this is the same reason for a place to rotate faster ...which is near the equator and far from the equator
