Question

Describe the circle of illumination ​

Answer 1

Answer:

Explanation:

The circle of illumination is the division between day and night over the earth. The circle of illumination bisects (cuts in half) all latitudes on the spring and autumnal equinoxes. At this time, all places have equal day length (12 hours). The circle of illumination always bisects the equator (0 degrees latitude).

Answer 2

Answer:

Examples of great circles include the Equator, all lines of longitude, the line that divides the earth into day and night called the circle of illumination , and the plane of ecliptic, which divides the earth into equal halves along the equator. Small circles are circles that cut the earth, but not into equal halves
