This question was popular and the candidates performed fairly well in (a) part of it but many mixed up the differences between equinoxes and solstices through the use of tabulation in (b) part.
The expected answers for the (b) part of the question which required the differences between equinoxes and solstices are:
- When equinoxes occur, the earth surface has equal day and night whereas solstices are associated with longer or shorter day and night.
Equinoxes occur on March 21st and September 22nd while solstices occur on June 21st and December 23rd
Equinoxes are experienced when overhead noon day sun is vertically on the equator while those of the solstices are vertically overhead on the Tropics of Cancer and Capricorn..
Equinoxes are associated with autumn and spring while solstices are associated with summer and winter.
