Ok so, is the earth’s atmosphere somehow locked to the earth like tidally? Or is ball earth and atmosphere independent of each other? Never seen this addressed.
In: Earth Science
The gas that makes up the atmosphere is held down by gravity. It’s not very dense so all the water and rocks sit beneath it.
Follow up question: if we consider the atmosphere belonging to earth. at the border of the atmosphere and space, do we lose a bit of earth on a regular basis because it just gets swooped out of earth’s gravity?
Gravity pulls stuff together. The atmosphere is basically a ball of gas that is held to the earth by earth’s gravitational field. Some gases, like helium, are light enough that they can escape the atmosphere and float off in to space.
