  What precisely is the troposphere? The troposphere is the atmosphere's innermost layer.   The layer in which we live The troposphere is closest to the Earth's surface. "Tropos" refers to change. This layer gets its name from the constantly changing weather that mixes up the gases in this part of our atmosphere.   Depending on where you are on Earth, the troposphere is between 5 and 9 miles (8 and 14 kilometers) thick. The North and South Poles have the thinnest ice. The air we breathe and the clouds in the sky are found in this layer. In this layer, the air is the densest. Indeed, the troposphere accounts for three-quarters of the total mass of the atmosphere. There is 78% nitrogen and 21% oxygen in the air here. Argon, water vapor, and carbon dioxide make up the remaining 1%.   The troposphere is what you experience when you feel the wind on your face, see clouds in the sky, or watch a bird flap its wings in flight. It's a nice layer to live in.

  What exactly is the stratosphere? The stratosphere is an atmospheric layer on Earth. The stratosphere is located above the troposphere and below the mesosphere. The layer is composed of layers The stratosphere is located above the troposphere and below the mesosphere. "Strat" stands for layer. Our atmosphere's layer has its own set of layers. Because there are no storms or turbulence to mix the air here, cold, heavy air is at the bottom and warm, light air is at the top. That is the inverse of how the layers function in the troposphere, where we live. If you were to climb a mountain in the stratosphere, you would have to remove your warm clothes as you got closer to the top, rather than putting them on as we normally do. However, there are no mountains high enough to reach the stratosphere, so you don't have to be concerned. This layer has a thickness of 22 miles (35 kilometers). The ozone layer, which is extremely important, is found in the stratosphere. ...
