Question 1901Navigation General70% to pass
A great circle will intersect the equator at how many degrees of longitude apart?
AI Explanation
The correct answer is B) 180°.
A great circle is the shortest distance between two points on a sphere, and it always intersects the equator at 90° angles. Since the equator is a complete circle around the Earth, a great circle will intersect the equator at two points that are 180° of longitude apart.
The other options are incorrect because: A) 0° would not be a great circle, C) 90° would be the distance between the poles, and D) 45° is not the correct angular separation for a great circle.
