Troposphere
The lowest layer of the atmosphere and contains about 95 percent of the mass of air in the Earth's atmosphere. The troposphere extends from the Earth's surface up to about 10 to 15 kilometers. All weather processes take place in the troposphere. Ozone that is formed in the troposphere plays a significant role in both the greenhouse gas effect and urban smog. See ozone precursors, stratosphere, atmosphere. (source: EPA) Background from Wikipedia View of Earth's troposphere from an airplane. The Troposphere is the lowermost portion of Earth's atmosphere. It is the densest layer of the atmosphere and contains approximately 75% of the mass of the atmosphere and almost all the water vapor and aerosol. The troposphere extends from the Earth's surface up to the tropopause where the stratosphere begins. The depth of the troposphere is greatest in the tropics (about 16km) and smallest at the poles (about 8km). The word troposphere stems from the Greek "tropos" for "turning" or "mixing". The troposphere is the most turbulent part of the atmosphere and is the part of the atmosphere in which most weather phenomena are seen. Generally, jet aircraft fly just above the troposphere to avoid turbulence.
