Then the sea is getting warmer and growing larger because of that. The atmosphere is warming is it growing larger?? ID: 22463 · Reply Quote

The atmosphere is warming is it growing larger?? Well, I\'m no expert but I\'d like to give my opinion. The sea rising in itself must be pushing the atmosphere up. Much of this must be compressing, even if it\'s on a minute scale, since the effects of gravity pull it back down, so atmospheric pressures must go up. If you then warm up that air, it expands, creating a greater volume which tends to push up to make room for it. Gravity will pull it down again, more compression. I expect eventually someone will coin the term \'hard air\'. ID: 22466 · Reply Quote

At times when there is a lot of solar activity, it has expanded way past the low Earth orbit satellites, such as the Space Station, adding to the drag on them, and causing their orbits to decay. This has necessitated that they be boosted back up into a higher orbit. ID: 22471 · Reply Quote
