why is tropospheremost important layer for life on earth
Answers
Answer:It isn’t. Sure, it is the most massive, turbulent, and so on but the effect of greenhouse gasses is amplified at the tropopause.
RE: “Why is the troposphere the most important layer of atmosphere?”
The tropopause is just above all of that water. It is where some of that thermal energy from below has a chance to escape from the planet and go all the way to space. This is where cooling happens - or not.
The tropopause is where it is because it is where water isn’t. Or maybe think of it the other way around. The troposphere is the way it is because water can exist in it in all three phases and it absorbs and emits energy in many ways. This confines water because it is forced to precipitate out before it gets too cold or too thin.
The amount and temperature in a column of air controls the altitude at which a greenhouse gas gets thin enough to allow half of the energy it emits to escape to space. The warmer that column of air, the higher that critical altitude is, and the colder the greenhouse gas is at that critical altitude. The more the amount of greenhouse gas in that column of air, the higher that critical altitude is, and the colder the greenhouse gas is at that critical altitude and the less energy it can radiate to space. So the air below it gets warmer - and around and around we go. This is the positive feedback loop that makes greenhouse gasses so influential
Answer:
- it consist of life supporting gas without which we can't live
ex : 78 % nitrogen , 21% oxygen is present
2. it plays a crucial role in moderating the temperature on the earth . because of which we are able to live .
ex: green house effect , convection current etc
3. it is also important in the process water cycle
4. it is a layer of weather change that affects the climate of that region
