The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
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.
Because people are not able to fly without a airplanes.
CO2 is a well-mixed gas in the Earth's atmosphere, meaning it is distributed fairly evenly throughout the various layers. However, other gases such as nitrogen and oxygen make up the majority of the atmosphere and are heavier than CO2, preventing CO2 from forming a distinct lower layer. Gravity helps keep all gases relatively well-mixed in the atmosphere.
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.
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.
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.
Airplanes changed the way of life for many because it meant being able to travel long distances in a very short amount of time. What might take 6 hours to drive will only take 1 hour to fly.
