(1) Where is the troposphere and stratosphere? What are they made up of?
The troposphere and the stratosphere are layers within the atmosphere closest to the Earth. The closest, the troposphere, is from the surface to 5-10 miles (8-16 km) up (at the tropopause), and is home to elements and compounds that cycle through the ecosphere, as well as to weather - clouds, water vapor, and air currents. Because of the mixing of the air, pollutants can be washed back to the earth through rain. The stratosphere is the next atmospheric layer, reaching about 40 miles (64 km) upwards, and contains ozone (03). Without vertical mixing or precipitation, pollutants can stay indefinitely.
