Question

Day and night temperature is almost equal in __________.
A. Uttar Pradesh
B. Andaman and Nicobar
C. Chandigarh
D. Rajasthan

Answer 1

Hint: As the sun rays fall directly on the equator first, the equator receives equal day and night throughout the year because it does not tilt in relation to the sun's location. The angle at which the Earth is tilted at approximately $23.5$ degrees.

Complete step-by-step solution:
As Andaman and Nicobar Islands lie close to the equator, they receive equal day and night throughout the year. Because of the tilted axis of the Earth, the poles and locations away from the equator lean away from or towards the sun as an orbit is completed, while the equator stays in the same location relative to the sun.
With the planet’s rotation around the sun, the poles lean closer to the sun. This is what produces the seasons. Since the Earth's equator remains nearly the same distance away at all times throughout the entire orbit around the sun and this then results in an almost uniform balance of day and night for locations closest to the equator throughout the year. Thus, the level of sunlight received throughout the year is nearly constant. The tropics have only the rainy season and the dry season, instead of four distinct seasons. The temperatures in the tropics tend to stay within a given range, although influenced by the warming and cooling of the rest of the planet, there are dramatic changes in weather patterns.

Thus, option (B) is correct.

Note: Even if the Earth had no tilt in its axis of rotation, the planet would still have an equator, which would still receive uniform sunlight throughout the year.
