Question The following graphs show the sunrise and sunset times across the year at 4 locations in India. Observe how the graphs are organised. Are you able to identify which lines indicate the sunrise and which indicate the sunset?
Answer the following questions based on the graphs:
(i) At which place does the sun rise the earliest in January? What is the approximate day length at this place in January?
(ii) Which place has the longest day length over the year?
(iii) Share your observations — what do you
Yes, we can identify the lines. (i) In January, the sunrise was earliest in Kibithu. (approx 6:00) The day length is (16:00-6:00) = 10 hours (ii) The place with the longest day length over the year is Ghuar Moti. (iii) Observations are Longest day length – Ghuar Moti Shortest day length – Kanyakumari Earliest sunrise in Jan – Kibithu Latest sunset in Jan – Ghuar Moti I am curious to find out the seasonal variation of sunrise and sunset, or day length, for any particular location.
