What if Earth Lost its Atmosphere? | #aumsum #kids #science #education #children

Sound travels to our ears by vibrating air molecules which are present all around us. Now no atmosphere means no air. Hence, there would be complete silence.
Secondly, no atmosphere means no oxygen, life on land would not last for more than 5 minutes. But life inside oceans might continue for some time as fishes will use dissolved oxygen to survive. Eventually even that supply will run out.
Thirdly, no atmosphere means no clouds, our sky would lose its magnificent blue color, it would look just as black as outer space.
Fourthly, unfortunately birds can't fly in vacuum, they will drop down to earth.
Lastly, without any atmosphere, days would be shorter by 4 minutes while nights longer as atmospheric refraction advances sunrise by 2 minutes and delays sunset by 2 minutes.
