Question

2 Give reasons and explain
If there were no atmosphere around the Earth, the temperature of Earth in the daytime and night-time would go extremely high and low, respectively.

I will mark as brainlist if you will give correct answer. I will report if it would wrong answer.​

Answer 1

ANSWER : Increase during day and decrease during night

EXPLAINING: there were no atmosphere around the earth, the temperature of the earth will increase during day and decrease during night. In the absence of atmosphere around the earth, it will be like a moon. There would be no life, no winds, no rains, no fires, no protection against harmful solar radiations. Due to absence of atmosphere around the moon, the temperature ranges from -1900C to 1100C. Air is a bad conductor of heat. The atmosphere has an average temperature of the earth almost steady during the day and night. It prevents sudden increase in temperature during the day time. Also, it decreases the rate of escape of heat during night time.

Thus, the correct answer is 'Increase during day and decrease during night.'

Answer 2

Answer:

$\huge \bigstar$$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$$\huge \bigstar$$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$$\huge \bigstar$$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$

Explanation:

As per the discription you know about the atmosphere and it's layer we can easily understand that the atmosphere has an average temperature for day and night. If there were no atmosphere around the earth, the temperature would get affected. In the absence of atmosphere, there would be no life, no rains, no winds, no fires and also no ozone layer that would be used as a protection layer against harmful radiations. The earth was becoming like a moon that had temperatures ranging from −190∘C to 110∘C.
