PPT-ALL ABOUT OZONE TROPOSPHERE

A layer of the atmosphere that is closest to the Earths surface Almost all weather occurs here Temperature decreases as altitude increases STRATOSPHERE Layer above the troposphere Extends from 1850 km. Lesson Objectives. Describe how the temperature of the atmosphere changes with altitude.. Outline the properties of the troposphere.. Explain the role of the ozone layer in the stratosphere.. Describe conditions in the mesosphere.. The . troposphere. is the lowest layer of Earth's atmosphere. The troposphere starts at Earth's surface and goes up to a height of 7 to 20 km (4 to 12 miles, or 23,000 to 65,000 feet) above sea level. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Almost all weather occurs within this layer. Air is warmest at the bottom of the troposphere near ground level. Higher up it gets colder. Air pressure and the density of the air are also less at high altitudes. Nearly all of the water vapor and dust particles in the atmosphere are in the troposphere. That is why most clouds are found in this lowest layer, too. The troposphere is heated from below. The warm air, heated by the sun, tends to rise. That keeps the air in the troposphere "stirred up". The top of the troposphere is quite cold. Air also gets 'thinner' as you go higher up. . the Upper Troposphere - Lower Stratosphere. K. . Wargan, . S. . Pawson. , . M. . Olsen, . J. . Witte, . A. .

Ozone is a major pollutant. It does billions of dollars worth of damage to agricultural crops each year and is the principal culprit in photochemical smog. Ozone, however, exists throughout the troposphere and, as a major OH source and a greenhouse gas, plays a central role in many biogeochemical cycles.
