Question 10:

The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west but the watches show the same time. How does it happen?

Or

State the reason for time lag between sunrise in the easternmost and westernmost horizons of India.

Answer:

India has a longitudinal extent of 30 ° from east to west. Due to this, there is a time lag of two hours between sunrise on the esternmost and the westernmost horizons of India. The earth takes 4 minutes to cover 1 ° of longitude. Therefore, in order to cover 30 ° of longitude, a time period of two hours is required. Hence, when it is 6 a.m. in Arunachal Pradesh, it is still 4 a.m. in Gujarat. But the clocks in all parts of India run according to the standard time measured from 82½ ° E longitude. So, the clocks in Arunachal Pradesh and Gujarat show the same time despite the difference in the time of sunrise.

Question 11:

‘The central location of India at the head of the Indian Ocean is considered of great significance’. Why?

Answer:

India lies at the head of the Indian Ocean. The Indian Ocean extends between 40 ° E to 120 ° E longitudes, with Kanniyakumari located along 80 ° E longitude. The Indian Ocean encloses India from three directions East, West and South. India occupies a centrally located strategic position in the Indian Ocean. The Indian Ocean is the only ocean in the world named after a country. In the past, Indian culture spread towards East and South-East Asia through the Indian Ocean. Now, India is well connected to the European countries in the west and the countries of East Asia through the trans- Indian Ocean routes.

Question 12:

Why 82 ° 30’ E has been selected as the Standard Meridian of India?

Answer:

82 ° East is taken as the Standard Meridian of India and it passes through the city of Allahabad. Local time of Mirzapur, near Allahabad, is taken as the standard time all over India. It is a central meridian for India, as it divides the country into two equal halves. So it suits most parts of the country. Moreover, Nepal and Sri Lanka also adopted 82 ° E as the Standard Meridian so as to avoid time differences with India.

Show Answer
Question 13:

Why is the difference between the durations of day and night hardly felt at Kanniyakumari but not so in Kashmir?

Answer:

The North-South extent affects the length of day and night in different parts of India. Kanniyakumari is close to the equator where the sun is almost overhead all the year round. Hence, the length of days and nights are equal. The maximum difference between the length of day and night is hardly 45 minutes. But in Kashmir (37 ° N), the rays of the sun are always oblique, meaning slanting. So, difference between the length of day and night is as large as five hours. Days are longer than nights, due to the inclination of this part towards the sun during the summer season (Summer solstice).
