What would happen if it was thin? What would happen if it was thick? Little gravity? A ton of gravity? I need answers noww!!! HOMEWORK SUCKS!
 
If the atmosphere was thin, then the sun rays would penetrate it better and it would heat it up much more, it would absorb it and everything would be hotter, a lot hotter. If it was thick everything would be colder, if it was much thicker then the earth could become very frigid, never ice cold because the nuclear reaction in its core keep it pretty warm, but not hot enough for us.If there was a little gravity some of it or all of it would drift off into space and we wouldn't have one. And lastly if there was ton gravity the atmosphere would be denser. All the atoms would be pulled closer together and the atmosphere or the skies would be much hotter, but it would still protect us. Hope it helps.
 
IF we had a thin atmosphere:

-We would have less oxygen to breathe

-Would also be dangerous cause we wouldn't have an ozone layer to protect us from the sun's ultraviolet rays.

IF we had a thick atmosphere:

-Creatures would much larger than they are now (cause of how too much oxygen affects the body).

-Took much oxygen would cause temperatures to plummet drastically, which would freeze over the entire planet.

IF we had less gravity:

-Our body structure would be very weak due to weak gravity holding us down.

-The moon wouldn't be here in which earth's gravity holds it here.

-We wouldn't reproduce effectively

IF we had more gravity:

-We'd have to develop complex body structure to hold us up to the intense gravity

-It would be really hard to fly in the atmosphere like flying planes.

Hope this helps ^_-
 
If it was thin there would be hardly any people on earth if it was fat then there would b more people on earth if there was little gravity instead of walkin we be like moon walkin in astronaut suits with a lot of gravity it would be hard to jump
