Question

Explain, Why the Earth without its atmosphere would be inhospitably cold?

Answer 1

Answer:

Without its atmosphere earth would be inhospitably cold.

Explanation: In the absence  of atmospheric  gases, no extra heat will be trapped. All the heat would be radiated back from earth's surface.

Answer 2

Answer: The sun rays contains infrared radiations.

these are reflected back by the lower part of the atmosphere after being reflected by the surface of the earth and are trapped inside the atmosphere thus maintaining the earth's temperature at hospitable level without these rays being trapped the temperature of the earth will go down severely and thus the earth without its atmosphere would be inhospitably cold.
