how much does the troposphere extend to
Water vapor and particles of dust can also be found in the earth's air. Clouds float only in the troposphere, or the lowest part of the atmosphere. It is also here that all of the earth's wind, storms and other features of weather take place. The troposphere extends upward to a height of about 10 miles. Air gets thinner the farther it gets from earth. The stratosphere extends from the troposphere to about 30 miles above the earth. It is in this air that many jet airplanes fly.
