Q

Which defines the shortest distance between any two points on earth?

🔍 Key Concepts

• Great circle vs small circle on a sphere • Difference between great circle and rhumb line (loxodrome) navigation • What “shortest distance on the surface of a sphere” really means

💭 Think About

• Imagine Earth as a perfect sphere: what kind of circle lies in a plane that passes through the Earth’s center? • When you follow a constant compass heading, what kind of path are you tracing on the globe? Is that always the shortest way? • Which of the listed options is defined specifically by geometry on a sphere, not by navigation practice or abstract math curves?

✅ Before You Answer

• Be clear on the geometric definition of a great circle and a small circle • Recall that a rhumb line keeps a constant true course (constant bearing) on a Mercator chart • Recognize that a hyperbola is not a circle on a sphere but a different type of conic section in plane geometry
