Question

how does the atmosphere act as a blanket

Answer 1

The atmosphere acts as a blanket by trapping terrestrial radiation and keeping the Earth warm. So it ensures that there is the correct amount of heat required for life to exist. If it were not for the protective covering of the atmosphere, all the life forms of the Earth would have been either burnt during the day or frozen to death during the night.


Hope it helps!!

Answer 2

Atmosphere acts as blanket because it prevents harmful solar radiation on the earth and traps the heat during the night.
