Answer 2

Answer:

The answer is (c) circle of illumination

Explanation:

The circle of illumination is the circle that separates the globe into day and night.

• It is an imaginary boundary that divides the day from night and light from the darkness.
• The axis of the earth is an imaginary line that runs from top to bottom through its center.
• The earth revolves around the sun once every 365 1/4 days (one year). Over four years, six hours saved per year are combined to produce one day (24 hours).
• This extra day is added to February's calendar. As a result, we have a leap year every fourth year with 366 days.
• The circle of illumination cuts all latitudes in half on the spring and autumn equinoxes.
