Answer 2

Answer:

(a)equal days and equal night.

Explanation:

The term Equinox means equal days and equal night.The Earth occupies positions on 21 March and 23 September respectively. These are the positions of Equinoxes.In the Northern hemisphere 21 March is Spring or Vernal Equinox and 23 September is the Autumnal Equinox. The seasonal terms are reversed in the Southern hemisphere.

*The following characteristics prevail on these two dates:-

1.The rays of the Sun fall vertically on the Equator.

2.The North pole and South Pole lie at an equal distance from the Sun.

3.The days and nights are of equal duration(12 hours)throughout the world.

4.The dates of the Equinoxes coincide with the time of sunrise at one pole and sunset at the other pole.

5.The circle of illumination just touches both the poles and bisects all the parallels in these two positions.
