Question

Explain why Ahmedabad and Kolkata are able to see the noon sun directly overhead in a year but not Delhi?

Answer 1

Ahmedabad and Kolkata lie in the tropical zone while Delhi is slightly above the tropic of cancer.The two former cities get the sun overhead twice a year.This happens wile the suns rays shifts from the equator to the tropic and secondly when it moves away from the tropic to the equator.However in cities like Dehi which does not lie in the tropical zone it will not receive the noon sun overhead twice a year. I hope this will be right!
