Concept notes: India spans a significant longitudinal distance, causing a difference in sunrise times between the easternmost and westernmost parts of the country. Arunachal Pradesh, located in the far east, sees the sun rise earlier than Gujarat, in the far west. This difference is primarily due to the longitudinal span of the country.
Explanation: India is a vast country that spans a significant longitudinal distance, which affects the time of sunrise across different regions. The easternmost state, Arunachal Pradesh, is located at approximately 97°E longitude, while the westernmost state, Gujarat, is located at approximately 70°E longitude. This longitudinal difference of about 27 degrees results in a time difference of approximately 2 hours between the two states.
The Earth rotates from west to east, causing the eastern parts of a country to see the sunrise earlier than the western parts. In India, this means that the eastern states, such as Arunachal Pradesh, experience sunrise earlier than the western states, such as Gujarat. The time difference is not due to different time zones within India, as the country operates on a single standard time, known as Indian Standard Time (IST), which is 5 hours and 30 minutes ahead of Coordinated Universal Time (UTC+5:30).
The longitudinal difference between Arunachal Pradesh and Gujarat is significant enough to cause a noticeable difference in the time of sunrise. This difference is approximately 2 hours, making option C the correct answer. It is important to note that while the longitudinal distance between these two states is substantial, the actual time difference is not as large as some might think, due to the single time zone system in India.
Understanding this concept is crucial for students preparing for competitive examinations, as it tests their knowledge of Indian geography and the relationship between longitude and time. It also highlights the importance of understanding the single time zone system in India and how it affects the daily lives of people across different regions of the country.
