Atmosphere.

Our air holds a mixture of many gases, liquid droplets and unhurt particles, but 99% of our air is make up of atomic number 7 and group O. The life process of all plants and animals depend on due north and carbon dioxide. Plants produce oxygen by photosynthesis. The key to photosynthesis is the queen of chlorophyll, the green pigment in plants, to convert sunlight into chemical energy. In measuring the temperature of the atmosp hither we find that there atomic number 18 four-spot levels where the temperature varies greatly. These levels be troposphere, which because of gravity is held closest to the surface of the basis and rises to to the highest degree ten miles. The atmospheric conditions of the lower troposphere are referred to together with as weather. As you near the top of the troposphere the temperature decreases to as such(prenominal) as -60 degrees F. The stratosphere covers active the next forty miles and as you go higher(prenominal) into the stratospher e the temperature again rises. preceding(prenominal) the stratosphere, from about thirty miles to fifty miles is the mesosphere here the temperature again falls, dropping to as little as -140 degrees F. Above the mesosphere the temperature of the thermosphere varies easily with solar activity. The thin atmosphere is heated intensely by the suns rays and can reach temperatures to over 1800 degrees F. Ozonosphere and Ionosphere are excessively divisions in the atmosphere. Within the ozonosphere lies the ozone layer. Ozone is kinded by the disassociation of molecular(a) oxygen and the combining of atomic oxygen with molecular oxygen.

This is set up with the appropriate ultraviolet ! (UV) radiation and oxygen at an optimal altitude of about twenty miles. The ionosphere is made up of electrically charged ions and electrons that are trapped in the earths magnetic field. These form ionic layers in the upper role of the atmosphere. The ionosphere... Stick to pen about the atmosphere, dont stray off writing about tornadoes, lightning etc.. And if youre going to parley about lightning get any(prenominal) of the facts straight.
