Explanation:

C) Equal nights is the correct answer.

Answer 2

Explanation:

a. being before noon —abbreviation AM, a.m., or (British) am.

b. Meridian means "midday," just as meridiem does. ... Thus postmeridian (one word) and post meridiem (two words) mean "occurring after noon," "in the afternoon." When the abbreviations A. M. and P. M. are spelled out, the word should be meridiem (ante meridiem, post meridiem).

c. A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth. A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles.

d. Equinox comes from the Latin words aequi, which means "equal," and nox, which means "night." The vernal equinox is considered the first day of spring: finally, the day and night are of equal length.
