what exactly is your question? the earth has protective layers around it. they don't have energy, they are just there. now if something such as a meteor happens to fall towards earth, these layers act somewhat like barriers. now if the meteor(ite) is small enough, these layers will cause enough friction on the meteorite to burn up on entry. this is what happens to the space shuttle every time it returns from space. during reentry, the shuttle heats up, that is why it has a heat shield composed of many tiles. the space shuttle columbia became a fiery ride when it returned because the tiles were damaged when the shuttle blasted off. when it returned, the heat was more than the shuttle could bare, thus the fireballs that were seen.
so, in short, these layers (iono, trope, meso and a couple others) are not energetic, they are just resistant to motion involving gravity. much like running on land, then trying to do the same waist deep in a pool of water. (bad similie, but hopefully you get the point about the resistance factor.)

Leaving Earth's ecosystem would not require just about as a lot % as an merchandise entering the ambience builds up because of gravity. it truly is why reentry must be dealt with very heavily, or the gap commute will dissipate. The commute has to reenter at only the right attitude or it is going to both look off the ambience and again out into area, or ( if it reenters at too steep and attitude ) will dissipate using friction with the ambience.

the rotation of the earth plus the iron in the core of the earth gemnerates a magnetic field around the planet. The field trapped the different gases in the atmosphere.

The sun is the source of all energy on earth!

From the sun or from heat radiated from Earth (again, traced back to the sun).

i'm not sure but it could be the sun, well logically that's where everything get's its energy from, so i assume the atmosphere has energy inside of it. but i'm stupid, too.

My guess is that the spinning of the earth drives the movement of weather systems.
