At all times during the year, the circle of illumination: Group of answer choices a) divides Earth between northern and southern hemispheres. b) divides Earth into eastern and western halves. c) separates winter from summer. d) divides Earth between equal halves of lightness and darkness.

The correct answer is - d) divides Earth between equal halves of lightness and darkness.

Explanation:

The circle of illumination bisects the equator and it is an imaginary line that separates equal halves of lightness and darkness. It cuts all the latitudes into half spring and autumnal equinoxes. It distinguishes the day area or hemisphere on earth from the night hemisphere.

Earth separates into the Eastern Hemisphere and the Western Hemisphere by the prime meridian line whereas the line of zero degrees or the equator line divides Earth between northern and southern hemispheres.
