The molecules of gas are kept in lower atmosphere due to a special force. It is called gravity.
The force of gravity binds the hydrosphere and lower atmosphere to earth.
Air pressure is the weight of the air at a specific location. On the surface of the earth, we have the entire weight of the atmosphere pressing on us in the form of air molecules like O2, N2, and CO2. As we go higher and higher into the atmosphere, there are fewer molecules and so there is less weight pressing against us.
The stratospheric region contains ozone layer. It protects us from UV rays.
Compaction.
No, the good ozone is present in the stratosphere region of the atmosphere. The one located in the lower atmosphere is bad.
The atmosphere as we know it, has got 4 layers. Troposphere is the lowest.
Boeing aircraft can fly in the troposphere and lower stratosphere layers of Earth's atmosphere.
Air molecules are piled up on each other in our atmosphere. The lower the air molecules, the more weight they're under causing more pressure. Higher up the molecules have more space to move around in resulting in lower pressure.
The divisions of the atmosphere are not based on the presence of ozone. Ozone exists in all layers of the atmosphere, with a peak in the lower stratosphere. Ozone is considered a free radical, not an ion. Ions are found in the "ionosphere" which is also called the thermosphere, where the Sun's ionizing energies rip the molecules apart (and fresh ions arrive from the Sun).
The Boeing 747 can fly in the troposphere and lower stratosphere layers of Earth's atmosphere.

lower core, upper core, mantle, and crust
Air pollution
it is present in all layers. What gave you the idea it wasn't?
gravity helps pull down the layers of the atmosphere and the upper atmosphere is further away so its going to have less of a pull on it there for being less dense then the closest atmosphere. hoped that helped.
Simply put, the higher the altitude, the lower the density of the air molecules.
In a way. It's orbit got lower and lower, until it burned up when it started hitting the denser layers of Earth's atmosphere.
