Detailed explanation-1: -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.
Detailed explanation-2: -The longer the sun is out, the warmer the air becomes. Temperatures will continue to climb as long as Earth is receiving more incoming heat than it is radiating back into space. The re-radiation happens later in the day, making the hottest part of the day between 4 p.m. and 6 p.m. during the summer.
Detailed explanation-3: -Usually, the maximum temperature of a day is recorded during the afternoon because the sun is present overhead. At this time we not only get the heat directly from the sun but also from the earth’s surface.
Detailed explanation-4: -Vertical rays are hotter than slanting rays. As the vertical rays give more heat per unit area, the noon is hotter than morning and evening.
