The stratosphere
Jet airplanes can fly in the upper Troposphere and in the lower Stratosphere. In the upper Troposphere and in the lower Stratosphere there is the Jet Stream which gives jet planes a extra push.

The stratosphere
Oxygen in the atmosphere is important for life for two main reasons. First, oxygen makes up the ozone layer. The ozone layer is in the upper part of the atmosphere, and is made of O3 molecules-a particular type of oxygen molecule. It blocks harmful radiation from the sun and keeps it from reaching Earth's surface. Without an ozone layer, intense radiation from the sun reached the early Earth's surface, making life almost impossible. Secondly, oxygen in the atmosphere is necessary for animals, including humans, to breathe. No animals would have been able to breathe in Earth's early atmosphere.
In the troposphere (the layer of the earth that we live in), the temperature decreases with increasing height. The troposphere contains approximately 80% of the atmosphere's mass and 99% of its water vapour and aerosols.As you increase height, you reach areas of the atmosphere that have fewer and fewer air molecules (which means the air is less dense) because gravity is keeping the majority of air molecules closer to the ground. So, at higher altitudes, the air is less able to store heat.
Apparently it does, since we're able to see the sun and get around without flashlights in the daytime.
how scientist were able to arrive to the district layer of the earth
Daytime A 2006 study revealed that because airplane exhaust contrails reflect little or no sunlight during nighttime and wintertime flights, they are less able to compensate for the climate-warming gases they contain.

Advantage of aviation: Well, it shortens distances & travel times. Imaging not having an airplane? you wouldn't be able to travel to Europe Asia etc. You wouldn't be able to send packages to the other side of the word by next day delivery. Traveling in an airplane is by far the safest travel mean ever invented by man.
Ozone layer filers the UV rays.
Well to maintain the oxygen in the earth atmosphere you need to make sure that the level of global warming is decreasing and less fumes will be able to make up the ozone layer. With a thinner layer around the earth this means that oxygen will be able to enter and exit the earths surface, allowing oxygen to still stay in the atmosphere.
they created the first flying airplane and without them, we would not be able to travel abroad in an efficient way.
CO2 weighs 44 and it is heavier than Nitrogen and Oxygen...it is denser than Oxygen still it is able to mix with other gases in the atmosphere
Since we have an atmosphere that is made up of 4 layers. One the most outer layer the thermosphere. Then the 3 most outer layer is the mesosphere. Next is the Stratosphere the third most outer layer. Last the closest layer the Troposphere which is where we all live.
The planet Mercury does not have an atmosphere in the same way that the Earth has an atmosphere; it has only a very thin layer of gases far above its surface. Because sound cannot travel in a vacuum, there would be no speed of sound on Mercury.
They invented the first airplane and if we didn't have airplanes we wouldn't be able to travel across the oceans or to different states fast.
Rockets aren't necessarily good for space travel they are a necessity. You cant leave earth without a rocket... you wont be able to break through the atmosphere.
