Question

If there were no atmosphere around the earth, the temperature of the earth will

विकल्प

• increase

• go on decreasing

• increase during the day and decrease during the night

• be unaffected

Answer 1

increase during the day and decrease during the night

Explanation:

The atmosphere acts as a temperature buffer. It prevents the sudden increase in temperature during daylight hours. Further, during the night it slows down the escape of heat into outer space thereby preventing excessive cooling during the night. Due to this reason, the average temperature of the earth remains fairly steady. If there were no atmosphere around the earth then the temperature of the earth will become very high during the day and very low during the night.
