PPT-TROPOSPHERE

The troposphere is the lowest layer of Earths atmosphere The troposphere starts at Earths surface and goes up to a height of 7 to 20 km 4 to 12 miles or 23000 to 65000 feet above sea level Most of the mass about 7580 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 .

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.
