Question

Which part of the day is generally the hottest period all over India?
A) Noon
B) 1 pm
C) 3 pm
D) One cannot say.

Answer 1

Hint:
The time of 24 hours can be divided into dusk, morning, noon, dusk, and night. The temperature varies across all these phases. The temperature begins to rise with the rising of the sun in the early morning, attains a daily maximum in the noon, and then begins to drop after the sunset.

Complete Answer:
The temperature on Earth varies throughout the day and across the year. The latitude, altitude, and degree of inclination of the sun affect the temperature on earth. The time taken by the Earth to complete one rotation in its own axis is divided into day and night. During this duration, there is a variation of temperature on earth. It attains a peak during noon.
Around 3 pm the temperature is at its highest all over India. The heat continues to build all through noon while the sun is high in the sky. At around 3 pm the sun is low in the sky and the amount of heat leaving the Earth is more than the heat received by the earth.

Thus, option (C) is correct.

Note:
The different seasons on earth are due to the earth’s revolution around the sun. The temperature also varies across these seasons. The distance between the sun and the earth decides the temperature in these seasons. The different seasons experienced are spring, summer, autumn, and winter. The climate of the region also affects to a large extent the diurnal temperature range. Deserts being cloudless have an extremely high range of diurnal temperature. While the regions close to the sea have a maritime climate and have a small range of diurnal temperature.
