        Walk outside on an early Sunday morning. snatch up some time to admire the sunset, feel the wet dew down the stairs your feet, and then take a deep breath. Feel the solacement flow of air rushing into your lungs in an essential single-valued run low of life, known as the breathing cycle. Such a of import aspect of life would not be possible without the presence of the Earths just about precious resource, the Atmosphere. Unfortunately, people have begun to abuse this deliberate and pollution is on the rise, a new enemy for the old protector of the Earth.                  4.6 billion years ago, Earth was nothing often than a steaming ball of molten rock, an inhospitable get until somewhat 3 billion years ago when plants began to get wind up with their appearance and create vast amounts of oxygen. Over time, the strain create a complex structure consisting of several opposite works extending to an top of about three hundred miles. The troposphere is the closest layer at an elevated of about 10 miles. Nearly 80 share of atmospherical mass is found at this layer. Next is the stratosphere, a genuinely stable layer, at a pinnacle of about 10 to 30 miles above the surface. A lack of peeing desiccation at this height inhibits the formations of clouds and is the ideal height for most commercial message flights.

The mesosphere is 30 to 50 miles high and is the coldest sphere of the atmosphere ambit a chilly 198.64 degrees Kelvin. It is basically smooth of the same particles as the other two layers. Above the mesosphere is a zone which consists of jus! t now one-billionth of the total atmosphere. This layer is known as the thermosphere and is the largest layer, stretchiness from 50 miles from the ground to 300 miles. Finally, the exosphere is the last layer at a staggering height of 300 miles. It consists of light molecules of hydrogen and is extremely thin. These five layers...
