What describes the Great Circle Route?

The Great Circle Route refers to the shortest path on the surface of a sphere, which is particularly relevant for navigation and aviation. This concept arises from the geometry of a sphere, where a great circle is any circle on the surface of the sphere whose center coincides with the center of the sphere.

When traveling between two locations on the globe, a great circle route minimizes the distance traveled. For example, instead of a straight line measured on a flat map, the terrain's curvature is taken into account, showing that a more direct route would curve along the Earth's surface.

This concept is essential for long-distance travel, such as in air travel, where aircraft often follow great circle routes to save fuel and time.
