Q. Why is the day and night difference not felt so hardly at Kanyakumari but no so in Kashmir?
Ans. Kanyakumari is located 8° away from the equator. As equator receives direct sunlight, there will be no strong difference between day and night. Whereas, Kashmir is located at 37° away from the equator, so the difference between day and night is about 4 hours.
Q. Why is the difference in the duration of day and night very little in Kanyakumari while it is not so in the northern part of the country? Give specific reasons for your answer.
Ans. Kanyakumari in Tamil Nadu is located at the southern-most tip of India’s mainland. The latitude 8°4'N passes close to it. The place is thus near the equator and lies close to the equatorial region. As the sun shines directly over the equator all throughout the year, the duration of day and night is almost equal here. Hence, in Kanyakumari the difference in the duration of day and night is very little. But in the northern part of the country located to the north of the Tropic of Cancer away from the equator, the difference between the lengths of day and night becomes increasingly greater.

Q. The Tropic of Cancer passes half-way through the country. What does this imply?
(i) Places on either side of the Tropic of Cancer experience tropical climate. The tropical monsoon type of climate that India experiences is extreme on account of the Tropic of Cancer.
(ii) Places further south of the Indian Union away from the Tropic of Cancer have more equable climate being closer to equator. Places further north of the Tropic of Cancer have subtropical climate. The sun shines directly on the Tropic of Cancer on 21st June or Summer Solstice.
(iii) Countries in the Northern Hemisphere including India experience summer during this part of the year. It is also associated with maximum heating of tropics during this period that influences advance of monsoons or rainy season.
(iv) Areas along the Tropic of Cancer have their longest day on 21st June. These areas have their shortest day on 22nd December or Winter Solstice when the sun rays are directly overhead the Tropic of Capricorn.-
Q. The central location of India at the head of the Indian ocean is considered of great significance. Why?
Ans. India is the southward extension of the Asian continent and is located in a central position between the East and West Asia. The Indian Ocean provides a strategic central location to India, as it connects the East Asian Countries with the countries of Europe in the West. The Deccan Peninsula also protrudes into the Indian Ocean, thus helping India establish close contact with West Asia, Africa and Europe from the western coast and with Southeast and East Asia from the eastern coast. There is no other country like India in the world, which has such a long coastline on the Indian Ocean and thus, justifying the naming of an ocean after it.
