it may sound like a stupid question but since the time i heard of the big hole in our atmosphere, this question had been bothering me ever since. I watch nat geo and discovery channel but i never come across the answer. So, somebody please tell me, does the atmosphere turn with the earth or does it stay still while the earth turns?

no the atmosphere dosnt move with the earth, and it dosnt just sit ther either.
the atmosphere has it's own movements and directions, wind currents and atmospheric changed. it moves in all directions if you think about it, so it couldnt possible move with the earth. but move in it's own way. if it did jsut move with the earth, there would be no wind, you could get some helium baloons float up and wait a few hours and you'd be in china. lol you could go round the world in 24 hours. lol

I read somewhere that the turn of the earth, or lets say the rate of the sun rise is about 13 miles per minute. This means at the surface of the earth is turning about 780 MPH. At the surface the atmosphere around the earth is pretty much turning with the earth. The high and low pressure areas on the surface controls what direction the wind blows on the surface. However up where the jet stream is the wind is blowing west to east at about 200 to 250 MPH. There is a certain amount of drag between the earth and the air around it at the surface. The higher you go in the atmosphere the less the drag and the more the air slows down and tries to stand still. By the time you run out of our atmosphere the air, what little there is that high, has completely stopped moving with the earth. This is a very interesting subject and thanks for posting it.

I think the atmosphere which near to earth surface turns with the earth, because it is held by the earth gravitation. But for those in high altitude may not be. As we know, air in high altitude flows much quickly and very different with those near earth surface.
