Question

Direct rays of the sun fall on the equator on
(i) 21 March (ii) 21 June (iii) 22 December

NCERT Class 6th Social Science The Earth: Our Habitat Ch 3 Globe: Motions of the Earth

Answer 1

Direct rays of the sun fall on the equator on (i) 21st March.

On 23rd September too, the same thing happens yet again.

During these times neither of the poles (north pole or south pole) remain tilted at the direction of the sun.

So, everywhere on earth, there is equal day and equal nights.

This scenario is known as Equinox.

Answer 2

Option (i) i.e 21st March is the correct answer.

The direct rays of the sun fall on the equator only twice in the year. These two days include 21st March and 23rd September. The direct rays of the sun on the equator makes such a position where neither of  the poles is tilted towards the sun and so the whole earth  experiences equal days and equal nights which is being called as equinox.
