Question

Why does the atmosphere tempeture drop just before sunrise each morning?

Answer 1

The earth's surface is heated by the solar radiation during day time and the earth starts giving out this heat to space once the sun sets in the evening.This cooling of the earth continues throughout the night till the rise of the sun next morning.So the coldest time of the earth's surface occurs just before or at the time of sunrise.This is the reason why the lowest temperature is recorded just before or at the time of sunrise.
